Error Code OXC4EB8274 Printer Cartridge Jammed

HP OfficeJet 4630
Microsoft Windows 10 (64-bit)

Error Code OXC4EB8274 Printer Cartridge Jammed. I've tried unplugging and restarting several times, the cartridge is stuck on the right side. It does not move freely. I've had this printer for 4 years, prior to this error I was having problems with the alignment page printing. Any ideas how to fix this?

Error Code OXC4EB8274 Printer Cartridge Jammed



Welcome to HP Forums,

Let's get straight to it!


In some cases, removing the ink cartridges and resetting the printer can clear the error message.

  1. Turn on the printer.

  2. Wait until the printer is idle and silent before you continue.

  3. Disconnect the USB cable from the rear of the printer. If your printer has a network or wireless connection, leave it connected.

  4. Remove the ink cartridges from the printer.

  5. With the printer turned on, disconnect the power cord from the rear of the printer and from the wall outlet or power strip.

  6. Wait at least 60 seconds.

  7. Plug the power cord back into the wall outlet.


    HP recommends connecting the printer power cord directly to a wall outlet.

  8. Reconnect the power cord to the rear of the printer.

  9. Turn on the printer, if it does not automatically turn on.

    The printer might go through a warm-up period. The printer lights might flash, and the carriage might move.

  10. Wait until the warm-up period finishes and your printer is idle and silent before you proceed.

  11. Reinsert the ink cartridges, and then close the ink cartridge access door.

  12. If you receive a prompt to print a calibration page, do so.

  13. If you disconnected the USB cable, reconnect it to the rear of the printer.

  14. Try to print.

If the issue persists, please upgrade the printer firmware: click here for instructions.
