  13.XX PAPER JAM  Media is jammed at the specified location (and possibly at other locations). If
                           the message persists after all jams have been cleared, a sensor or sensor lever might be stuck or broken. For all jam messages,
                           do the following: 1. Remove jammed print media from the specified location. Check the entire paper path for other pieces of
                           media in the path. 2. Open and close the top cover to clear the message. 3. Check sensors and flags in the paper path for
                           proper operation.   
  13.0 PAPER JAM A
                           non-specific paper jam occurred. 1. Remove jammed media from the specified location. 2. Verify the paper tray is fully closed.
                           3. Inspect and/or replace the feed and separation rollers. 4. Ensure there is no obstruction in the path, such as a torn piece
                           of paper. 5. Open and close the top cover to clear the message. 6. Check sensors and flags for proper operation. 
                            
  13.1 PAPER JAM OPEN INPUT TRAYS  Paper-delay
                           jam at paper feed area. 1. Ensure that paper trays are loaded and adjusted properly so media can feed from the tray. It might
                           be necessary to reduce the stack height of media in the tray. 2. Check the input area for obstructions such as media in the
                           path. Also check to see if the registration assembly damaged or unseated. 3. Replace any defective sensors or flags. 4. Verify
                           the media meets the specifications. 5. Check the pickup feed and separation rollers for unusual wear. Replace as needed. 6.
                           Rotate the media in the input tray by 180° and/or turn it over On NX engines this is most likely the fuser flag or the
                           ACPM. The ACPM has a photo-sensor hard-wired to the back of it.  
  13.10 PAPER JAM CHECK DUPLEXER  Jam at duplexer. 1. Check the duplexer and the rear area of the printer for obstructions or
                           damage. 2. Check the duplexer for proper operation. Replace the duplexer if a sensor is defective. On a 5si, 8000, or 8100
                           series laserjet a Duplex Jam can be caused by a tray 2 and 3 feed assembly failure.  13.14 For Laserjet 5si. This error is caused by a defective paper control PCA Replace paper control PCA. 
                            
  13.2 PAPER JAM OPEN INPUT TRAYS  Paper-stopped
                           jam at paper-feed area. 1. Check the input area for obstructions such as paper in the path. Also check to see if the registration
                           assembly is damaged or if the transfer roller is out of place. 2. Replace any defective sensors or flags. 3. Ensure the media
                           does not exceed the maximum length. 4. If multiple sheets are feeding, it might be necessary to fan the media and reduce the
                           stack height. Also, replace separation pad. 5. Verify that the fuser is properly installed. On NX engines this is an input
                           jam.  
  13.20 PAPER JAM CHECK REAR DOOR  Media stopped in the
                           paper path during power on or when the top door was closed. 1. Remove all media in the paper path, and then open and close
                           the top cover. 2. If the message persists after all media is removed: Check if media is jammed in the pre-feed area. Replace
                           any defective sensors or flags   
                         
                        
                        
                        
                        
                        13.21 DOOR OPEN JAM  The top cover was open while printing. 1. Clear the jam and close the top door.
                           2. If the message persists, check the top door switch for proper operation.   
  13.5 PAPER JAM CHECK REAR
                           DOOR  Paper-delay jam at fuser. 1. Check the transfer roller
                           and small media belt to ensure they are operating and can feed print media. 2. Check the paper path for obstructions at the
                           transfer roller, toner cartridge, paper feed assembly, and fuser. 3. Replace any defective sensors or flags. 4. Turn the media
                           stack over and/ or rotate it by 180° in the input tray. If still persists - replace fuser, then DC controller.  
  13.6
                           PAPER JAM CHECK REAR DOOR  Paper-stopped jam at fuser. 1. Check
                           the paper path for obstructions at the fuser and output/delivery area. 3. Replace any defective sensors or flags. 
                            
  13.99 PAPER JAM [LOCATION]  A non-specific paper jam occurred. 1. Remove jammed media from the specified
                           location. 2. Verify the paper tray is fully closed. 3. Inspect and/or replace the feed and separation rollers. 4. Ensure there
                           is no obstruction in the path, such as a torn piece of paper. 5. Open and close the top cover to clear the message. 6. Check
                           sensors and flags for proper operation 
  20 INSUFFICIENT MEMORY  The printer received more data than can fit in available memory. You might have tried to transfer too many macros, soft
                           fonts, or complex graphics. Press GO to print the transferred data (some data might be lost). Advise the customer to simplify
                           the print job or install additional memory   
  21 PAGE TOO COMPLEX  The data (dense text, rules, raster or vector graphics) sent to the printer is too complex Press GO
                           to print the transferred data. (Some data might be lost.) Advise the customer to simplify the print job. More memory might
                           help.  
  40 EIO x BAD TRANSMISSION  The connection has been broken between the printer and the EIO card in the specified
                           slot. (Data loss might occur in this situation.) 1. Press GO to clear the error message and continue printing. 2. Reseat the
                           EIO card in slot [X].  
  41.3 UNEXPECTED PAPER SIZE  The printer detected a media size different from what it was expecting. This is typically caused if two or more sheets
                           stick together in the printer or if the tray is not properly adjusted. 1. Reload the tray with the correct print media size.
                           2. Ensure that media in the tray is loaded under the front and back tabs. 3. If you are printing from tray 1, verify that
                           the correct paper size is selected in the control panel. 4. If you are printing from tray 2, 3, or 4, verify that the three
                           paper-size adjustments (length guide, width guide, size-selector switch) on the paper tray have been made correctly. Make
                           sure the media is under the corner tabs. 5. After performing the actions above, press GO. The page containing the error will
                           automatically be reprinted if jam recovery is enabled. (Or, you might want to press CANCEL JOB to clear the job from the printer’s
                           memory.) For the 4000, 4050, and 4100 series the paper feed assembly could be bad. Also the paper feed/registration sensors
                           could be knocked out of place. On EX engine printers this error is caused by a bad PIU (paper input unit).  
  41.5 PRINTER ERROR  The media reached the PS102 or PS103 sensor too early. 1. This
                           error usually occurs with smooth media, such as transparencies or labels. If the problem persists when using tray 1, load
                           media one sheet at a time. If the problem persists when using trays 3 and 4, replace the feed and separation rollers. 2. Check
                           sensors PS102 and PS103 for proper operation For the 4000, 4050, and 4100 series the paper feed assembly could be bad. Also
                           the paper feed/registration sensors could be knocked out of place. On EX engine printers this error is caused by a bad PIU
                           (paper input unit). 
                         
                        
                        41.x PRINTER ERROR
                            A temporary printing error has occurred. The page containing the error will automatically be reprinted. If the error
                           persists: 1. Reseat the connections to the laser scanner and then to the engine controller board. 2. Replace the laser scanner.
                           3. Replace the engine controller board  
  49.XX PRINTER ERROR A

                           turn the printer on. 3. Try printing a job from a different software application. If the job prints, go back to the first
                           application and try printing a different file. (If the message only appears with a certain software application or print job,
                           contact the software vendor for assistance.) 4. If the message persists with different software applications and print jobs,
                           disconnect all cables to the printer that connect it to the network or printer. 5. Turn the printer off. 6. Remove all memory
                           DIMMs or third-party DIMMs from the printer. (Do not remove the firmware DIMM in the lowest DIMM slot.) 7. Remove all EIO
                           devices from the printer. 8. Turn the printer on. 9. If the error no longer exists, install each DIMM and EIO device one at
                           a time, making sure to turn the printer off and back on as you install each device. 10. Replace a DIMM or EIO device if you
                           determine that it causes the error. 11. Remember to reconnect all cables that connect the printer to the network or computer.
                           12. If the error persists, replace the firmware DIMM. 13. Replace the formatter. This error is usually caused by a bad formatter
                           board. 
  50.4 PRINTER ERROR  A problem exists with the customer’s
                           line voltage. 1. Remove the printer from any UPS supplies, additional power supplies, or power strips. 2. Plug the printer
                           into a wall outlet and see if this resolves the problem. 3. If the printer is already plugged into a wall outlet, try another
                           power source in the building that is independent of the one currently being used. 4. The line voltage and current source at
                           the printer location might need to be inspected to ensure that it meets the printer’s electrical specifications. 
                            
  50.X FUSER ERROR  A fuser error has occurred.
                           1. Turn the printer off, wait 10 minutes, and then turn the printer on. 2. If the message persists, reseat the fuser. If that
                           does not work, replace the fuser. To check the fuser, turn the printer off and remove the fuser. Measure the resistance between
                           the fuser connectors. If it is not within the proper range, replace the fuser. If there is not continuity between the fuser
                           connectors neutral and hot with the fuser removed, replace the fuser. If the problem is not related to the fuser, replace
                           the engine controller board.

                           then turn the printer on. 2. Reseat the duplexer. 3. Replace the duplexer   
  79 SERVICE [XXXX]  The printer detected an error. 1. Press CANCEL JOB to clear the print job from
                           the printer memory. 2. Turn the printer off, and then turn the printer on. 3. Try printing a job from a different software
                           application. If the job prints, go back to the first application and try printing a different file. (If the message only appears
                           with a certain software application or print job, contact the software vendor for assistance.) 4. If the message persists
                           with different software applications and print jobs, disconnect all cables to the printer that connect it to the network or
                           printer. 5. Turn the printer off. 6. Remove all memory DIMMs or third-party DIMMs from the printer. (Do not remove the firmware
                           DIMM in the lowest DIMM slot.) 7. Remove all EIO devices from the printer. 8. Turn the printer on. 9. If the error no longer
                           exists, install each DIMM and EIO device one at a time, making sure to turn the printer off and back on as you install each
                           device. 10. Replace a DIMM or EIO device if you determine that it causes the error. 11. Remember to reconnect all cables that
                           connect the printer to the network or computer. 12. If the error persists, replace the firmware DIMM. 13. Replace the formatter. 
                             
  79 & 80 errors  For trouble shooting 79 and 80 errors you want to determine if external I/O devices are the cause
                           or if it is the formatter. Remove all external I/O devices (JetDirect, memory, etc.) and see if problem persists. If not,
                           replace the formatter.

 ACCESS DENIED
                           MENUS LOCKED The control panel function you are trying to use
                           has been locked by the network administrator to prevent unauthorized access. Ask the network administrator to unlock the function.
                           Perform a cold reset. This will reset the printer to factory defaults. If a JetDirect network card is installed it will also
                           reset the IP address and other settings so you might want to remove the JetDirect before performing the cold reset. 
  BAD DUPLEXER CONNECTION  The duplexer is not correctly installed. 1. Ensure that the right-angle power cord that shipped with the printer is
                           being used. 2. Turn the printer off. 3. Remove and reinstall the duplexer. 4. Turn the printer off and back on. 5. If the
                           message persists, make sure the duplexer is connected and the connector is not damaged. 6. Replace the duplexer. Not all printers
                           will require a right angle power cord but it is ESSENTIAL for those that need it. On printers like the 4000, 4050, and 4100
                           the duplexer will not install correctly with a standard power cord.

                           paper-handling menu.
  ENVELOPE FEEDER TYPE = [xxxxx]  The printer has received a job under the following conditions: The envelope type the job requested is not available in the
                           printer. Envelopes have been placed in the envelope feeder (thus triggering the paper sensor). You can take either of the
                           following actions: 1. Press SELECT to accept the paper type and then press GO. 2. Press +VALUE- to change the type, press
                           SELECT to accept the new type, and then press GO to continue.
  FILE SYSTEM IS FULL  The disk file system is full. 1. Delete
                           all unnecessary files from the EIO disk and then try again. Use HP Resource Manager to download or delete files and fonts.
                           (See the software help for more information.) 2. Advise the customer to increase the permanent storage (use a larger EIO disk
                           or add a RAM DIMM).
  FLASH DEVICE FAILURE  The flash DIMM had a critical or fatal failure. 1. Reseat the flash DIMM and ensure
                           it is locked into place. 2. Remove the flash DIMM and replace it with a new one. The formatter could also be bad. 
  FLASH FILE OPERATION FAILED  The requested operation could not be performed
                           (for example, attempting to download a file to a nonexistent directory). 1. Check the file name and the directory name. 2.
                           Reseat the flash DIMM. 3. Retry the operation.
  FLASH FILE
                           SYSTEM IS FULL  The flash file system is full. Delete unnecessary files from the flash DIMM and try again. Use HP Resource
                           Manager to download or delete files and fonts. (See the software help for more information.)
  FLASH IS WRITE PROTECTED  The
                           flash DIMM is protected and no new files can be written to it. Disable the write protection through HP Resource Manager.
  HP TONER DETECTED alternates with PRESS GO TO CONTINUE  The printer has detected that the toner cartridge is not a genuine
                           HP toner cartridge because it does not see or recognize the toner cartridge’s identification (model, manufacturing date,
                           and serial number). 1. Make sure the toner cartridge is a genuine HP toner cartridge. A non-HP toner cartridge will produce
                           this error. Any printer repair required as a result of using non-HP toner is not covered under the printer warranty. 2. If
                           the HP toner cartridge is new, the Elabel (cartridge memory) is missing or has been tampered with. 3. If the HP toner cartridge
                           is used, the printer will not recognize the cartridge until 20 pages have been printed. After 20 pages have been printed,
                           the error message disappears. 4. If the HP toner cartridge is used, and the error message remains after 20 pages have been
                           printed, the cartridge has previously run out of toner. Replace the toner cartridge.
  INPUT DEVICE CONDITION [XX.YY] An
                           input paper-handling device has a condition that needs attention before printing can resume. 1st X = Device number in chain

                           device for assistance.   
  INSTALL DUPLEXER  The
                           printer is unable to print the current job because the duplexer is not installed or not inserted correctly. 1. Turn the printer
                           power off. Install or reinsert the duplexer and ensure it is fully seated. 2. Ensure the right-angle power cord is used for
                           the printer.   
  INSTALL TONER CARTRIDGE  The toner cartridge
                           has been removed and must be reinstalled for printing to continue. Reinstall the toner cartridge and ensure it is fully seated.
                           The high voltage power supply might also cause this error.  
  INSTALL TRAY [X]  The printer is unable to print the current job because the specified tray [X] is open or not inserted correctly
                           1. Reinsert the specified tray. 2. Check for damaged tabs on the right side of the tray. 3. Check for damaged tray sensor
                           switches in the printer. 4. Replace the PCA controller in the feeder.
  LOADING PROGRAM [NUMBER] alternates with DO NOT POWER OFF  Programs and fonts can be stored on the printer’s file system. At startup time, these entities are loaded into
                           RAM. (These entities can take a long time to load into RAM depending on the size and number of entities being loaded.) The
                           <NUMBER> specifies a sequence number indicating the current program being loaded. Wait for the program to load.
  MANUALLY FEED [TYPE] [SIZE]  A manual feed was requested.-There is no media in tray 1.- The wrong size of media is loaded. - The control
                           panel is not set for the size and type of media loaded. 1. Load the requested paper into tray 1. 2. Press GO (or READY on
                           older printers) if the desired paper is already loaded in tray 1. 3. Press -VALUE+ to scroll through other available types
                           and sizes. 4. Press SELECT to accept the alternate type or size. If manual feed was not what you were expecting, check your
                           software settings.
  MEMORY FULL STORED DATA LOST  There is no available memory in the printer. The current job might not print correctly
                           and some resources (such as downloaded fonts or macros) might have been deleted. Press GO to continue. Add more memory to
                           the printer or to simplify the print job.
  MEMORY SETTINGS
                           CHANGED  The printer changed its memory settings because it
                           did not have enough memory to use the previous settings for I/O buffering and resource saving. This usually occurs after removing
                           memory from the printer, adding a duplexer, or adding a printer language. Press GO to continue. Add more memory to the printer
                           or to simplify the print job.
  MEMORY SHORTAGE JOB CLEARED
                            The printer did not have enough free memory to print the entire
                           job. The remainder of the job will not print and will be cleared from memory. Press GO to continue. Add more memory to the
                           printer or to simplify the print job
  OFFLINE  The printer is offline Press GO or READY or ONLINE to place the printer online.
  OUTPUT BIN FULL alternates with CLEAR PAPER FROM [BINNAME]
                            The output bin is full and needs to be emptied. Remove the
                           sheets from the output bin. Also, the output sensor could be out of alignment, or the photo-sensor for the output bin could
                           be bad.  
  PAPER WRAPPED AROUND FUSER  Print media is
                           wrapped around the fuser. 1. Turn the printer off to keep the media from wrapping more firmly around the fuser. 2. Open the
                           top cover and remove the toner cartridge. 3. Remove all the visible media. 4. Leave the printer turned off and remove the
                           fuser to remove any remaining print media.   
  PERFORM PRINTER MAINTENANCE  To ensure optimum print quality, the printer prompts the customer to have routine maintenance installed.
                           Install the printer maintenance kit. You must reset the maintenance page count after performing printer maintenance. Note
                           The printer maintenance kit is a consumable item and is not covered under warranty, OIS provides 6 months warranty or 50k
                           prints  
  PROCESSING CLEANING PAGE  The printer is conducting
                           the manual cleaning-page process. Wait for the job to finish. This can take up to 2.5 minutes.   
  PROCESSING
                           JOB  The printer is processing a job. Wait for the job to finish.
                           This can take several minutes for a complex print job. If the printer "hangs up" on processing a job then it could
                           be a bad formatter board.  RAM DISK DEVICE  FAILURE  The RAM
                           disk had a critical or fatal failure. 1. Reseat the RAM disk. 2. Replace the RAM disk.   
  RAM DISK FILE OPERATION
                           FAILED  The requested operation could not be performed (for
                           example, attempting to download a file to a nonexistent directory). 1. Check the filename and directory name. 2. Reseat the
                           RAM disk. 3. Retry the operation.  
  RAM
                           DISK FILE SYSTEM IS FULL  The RAM disk file system is full.
                           1. Delete unnecessary files and then try again, or turn the printer off, and then turn the printer on to delete all files
                           on the device. (Delete files using HP Resource Manager or another software utility. See the software online help for more
                           information.) 2. If the message persists, increase the size of the RAM disk. Change the RAM disk size from the configuration
                           menu on the printer control panel. HP Resource Manager can also be used to increase or decrease the RAM disk size. 
  SHORTAGE
                           PAGE SIMPLIFIED  The printer had to compress the job to fit
                           it in available memory. Some data loss might have occurred. 1. Press GO to continue. (The print quality of these pages might
                           not be acceptable.) Add more memory to the printer or to simplify the print job.   
  RAM DISK IS WRITE PROTECTED
                            RAM disk is protected, and no new files can be written to it.
                           Disable the write protection through HP JetAdmin.     
  TONER LOW  The message first appears when about 15 percent of the toner is remaining in the toner cartridge (about 1,500 pages
                           remaining for the 10,000-page cartridge and about 900 pages remaining for the 6,000- page cartridge at five percent coverage).
                           Depending on how the printer has been configured in the configuration menu, it will either continue to print or stop. If the
                           printer has stopped, you can resume printing by pressing GO for each job. The high voltage power supply could also cause this
                           error. 
  TONER OUT  The toner cartridge has run out of toner. Depending
                           on how the printer has been configured, it will either continue to print or stop. Due to the resolution of the toner level
                           sensor, it is possible that a small amount of toner (less than one percent) might still be present in the cartridge. If the
                           printer has stopped, you can resume printing by pressing GO for each job. Replace toner cartridge. The high voltage power
                           supply could also cause this error.  
  TRAY [X] EMPTY [TYPE] [SIZE]  The specified tray is empty, but the current job does not need this tray in order to print correctly. If this message
                           appears and the tray contains print media, a sensor could be damaged. 1. Load the empty tray (x) to clear the message. If
                           you do not load the specified tray, the printer will continue printing from the next available tray, and the message remains.
                           2. If the message remains after the specified tray is loaded, check sensor arm flags for damage and be sure they move freely.
                           4. Replace defective paper out sensors.   
  TRAY [x] LOAD [TYPE] [SIZE] where x is tray 2, 3, or 4  This message occurs for the following reasons: Tray 2, 3, or 4

  TRAY 1 LOAD [TYPE] [SIZE]  The print job has
                           requested a size and/or type of media that is not loaded. Load the requested print media into tray 1 (or any other desired
                           tray). - Ensure that the trays are correctly adjusted for size. - The tray type settings (and size for tray 1) must be set
                           from the paper-handling menu. If this message appears and the correct media is loaded: - Ensure that all paper size adjustments
                           have been properly performed (see page 220). - Ensure the tray type setting is correct in the paper-handling menu. - Check
                           the size tabs on the right side of the tray. - Check the size switches and paper sensors. - Ensure the tray is fully seated.
