HP printer error codes

Every code below opens a full page: what HP documents the code to mean, what to check before acting on it, what to do if it returns, and a link to the HP document it was verified against.

29 of 29 catalogued HP codes published. The rest stay unpublished until their documentation has been read.

• 0x610000f6Carriage Jam — the print carriage has stalled or is physically obstructed, most often by a paper jam or a cartridge that isn't seated correctly. Not a firmware/communication fault.
• 13.xxPaper jam; sub-code identifies location in the paper path
• 33.05.0XSureStart error range covering boot-code corruption (33.05.00-03, auto-recovered, no action needed) and firmware that failed cryptographic BIOS validation (33.05.04-07, requires downloading firmware via the preboot menu) plus invalid boot/downgrade attempts (33.05.08-09).
• 33.05.1XWhitelisting error: a firmware file's digital signature failed validation, indicating tampering or a certificate problem. HP's fix: perform a Partial Clean, then if the device doesn't reboot to Ready, download firmware via the preboot menu.
• 33.05.2XIntrusion Detection error range: 33.05.21 flags a potential memory-corruption intrusion (possible malware injection); 33.05.22-24 indicate the intrusion-detection process couldn't scan or failed to initialize. HP's fix: power cycle the device (selecting Continue from the preboot menu will not clear it).
• 49Firmware / communication error; often clears on power cycle
• 59Internal motor error (drum motor startup/rotation fault). Variants indicate which motor/color: 59.05.60 (black), 59.06.60 (cyan), 59.07.60 (magenta), 59.08.60 (yellow); 59.C0 indicates a developer-disengagement motor rotation error.
• 79An internal firmware error, not specifically a network print server error. Power cycling often clears it; persistent cases point to firmware, incompatible DIMMs, or network services (e.g. IPv6/WS-Discovery) as contributing causes.
• 99.00.32Occurs when attempting to downgrade a SureStart-capable printer to non-SureStart firmware from a fully running state (EWS or Web Jetadmin) instead of via the preboot menu. HP's fix: the firmware was not actually downloaded — redo the downgrade using the preboot menu with physical access to the device.
• Er/01The printer's input tray is empty. HP's fix: load paper into the tray.
• Er/02A door on the printer is open. HP's fix: verify the top cover is fully closed.
• Er/03The printer failed to pick a sheet of paper for a print job. HP's fix: press Start Copy/Resume to retry the pickup.
• Er/04Paper is jammed in the input tray. HP's fix: open the print-cartridge door, remove the print cartridge, then pull the jammed sheet straight out (never at an angle) and reinstall.
• Er/05Paper is jammed in the toner-cartridge area inside the printer. HP's fix: remove the cartridge (keep it out of direct light), extract the jammed sheet, and reinstall.
• Er/06Paper is jammed in the output-bin area. HP's fix: open the cartridge door, then with both hands pull the jammed sheet free without sharp tools.
• Er/07The toner supply (cartridge) is missing or incorrectly installed. HP's fix: install or reinstall the cartridge.
• Er/08The toner cartridge has reached a Very Low level and the printer is configured to stop printing. HP's fix: replace the cartridge, or change the cartridge setting to Continue in the printer's Embedded Web Server.
• Er/11There is a problem with the toner cartridge itself. HP's fix: confirm the shipping tape/seal has been fully removed and that the cartridge is compatible and undamaged.
• Er/14The installed toner cartridge is HP-cartridge-protection locked to a different printer and is not authorized for use in this one. HP's fix: replace with an authorized cartridge.
• Er/17A non-genuine (non-HP) toner cartridge is installed; the printer's Cartridge Policy setting only allows Original HP cartridges. HP's fix: replace with a genuine HP cartridge.
• Er/25The paper loaded doesn't match the size requested by the print job. HP's fix: load the correct size, or press Start Copy/Resume to continue with the currently loaded paper.
• Er/26The printer experienced a general print-engine error. HP's fix: press Start Copy/Resume to continue; if it recurs, power the printer off for 30 seconds and back on.
• Er/30There is a problem with the flatbed scanner. HP's fix: disconnect power for 30 seconds, reconnect, and let the printer reinitialize; contact HP support if it persists.
• Er/50There is a problem with the print engine (also shown as Er/51, Er/52, Er/54, Er/55, Er/58, Er/59). HP's fix: power cycle the printer; contact HP support if the error persists.
• Er/61A wireless WPS connection attempt failed. HP's fix: press Cancel and retry the WPS pairing, or connect instead via the HP Smart app.
• Er/66There is a problem with the printer's wireless hardware. HP's fix: press Start Copy/Resume to continue without wireless; if it repeats, power cycle the printer.
• Er/74The printer hit a fatal, unrecoverable error (also shown as Er/76, Er/77). HP's fix: power cycle the printer; contact HP support if it persists.
• Er/75The printer is not connected to the internet, so it cannot validate the installed supply. HP's fix: reconnect the printer to the internet.
• Er/81Incorrect firmware was loaded onto the printer. HP's fix: press Start Copy/Resume to continue, then load the correct firmware.
