HP printers show error codes on the display, in HP Smart, or as Windows hex codes like 0x6100004a. This guide explains the most common codes on HP LaserJet, OfficeJet, DeskJet, and Envy printers — and what to try first.
Paper path and jam codes
- 0x6100004a / Jam: Paper stuck or sensor triggered — open all doors, clear path, see paper jam fix
- Tray empty or open: Reload paper, close tray firmly, match paper size in driver
Ink and toner codes
- 0x83c0000e: Cartridge problem — reseat, clean contacts, see cartridge not recognized
- Low ink / toner: Replace or shake toner on LaserJet; run printhead clean on inkjet
Communication and offline
- 49.xx.xx (LaserJet): Job or driver sent bad data — clear queue, update driver, firmware
- 79 (LaserJet): Firmware or accessory fault — power cycle, disconnect USB extras, update firmware
- Printer offline: Network or spooler — offline guide, spooler fix
HP Smart and Windows hex codes
Windows may show long codes in the print queue. Search the code on HP Support with your exact model number — fixes are often model-specific. Always note whether the code appears during printing, scanning, or at startup.
General recovery steps
- Power off, unplug 60 seconds, power on
- Update HP firmware via HP Smart (when available)
- Clear print queue and reinstall driver
- Print a configuration page — if that fails, focus on hardware; if it works, focus on PC software
Persistent or repeating codes
Same code after a full power cycle may need part replacement (fuser, formatter). Call before ordering parts — many codes are fixable remotely. Call (888) 423-7757 — available 24/7.
