Troubleshooting FAQ

Paper Jam in Input or Output Trayexpand_more
Press the Cancel button to attempt automatic clearing. If the jam persists, gently pull paper from the affected tray. Ensure no foreign objects remain in the paper path. For jams in the cartridge access area, turn off the printer, open the access door, and carefully remove obstructed paper. Always close the door before pressing Resume.
Low Ink or Cartridge Not Detectedexpand_more
Check the Ink Level icons on the control panel display. If an icon blinks with no segments and the Ink Alert light is on, remove the cartridge and verify the plastic protective tape has been removed. Clean the cartridge electrical contacts (gold-colored dots) with a dry, lint-free cloth. Reinsert the cartridge until it clicks, then close the access door. Replace cartridges with genuine HP 65 or 65XL when print quality becomes unacceptable.
Printer Not Printing or Offlineexpand_more
Verify the printer is powered on and paper is loaded in the input tray. Check your computer's print queue to ensure the printer is not paused or offline. If using a USB connection, disconnect and reconnect the cable. For wireless connections, confirm the Wireless light is on and showing a strong signal. Restart the print spooler service on your computer if the issue persists. Use the HP Print and Scan Doctor utility (Windows only) to diagnose connection problems automatically.
Poor Print Quality or Streaky Outputexpand_more
Verify you are using original HP cartridges and high-quality paper with the ColorLok logo. Check ink levels and replace cartridges if low. Use the printer software to align cartridges: open HP Utility (OS X) or the Printer Toolbox (Windows), then select the alignment option. Print a diagnostic page to inspect color and black output. If streaks or missing colors appear, clean the cartridges using the software maintenance options. Always allow cartridges to stay installed; removing them can cause drying.
Wireless Connection Dropping or Unavailableexpand_more
If the Wireless light is blinking with the Attention icon on, move the printer closer to your wireless router and ensure it is powered on. Press the Wireless button and Information button simultaneously to print a network test report for diagnostics. Check that your network password is correct and the printer is within range. If the light blinks fast for three seconds then turns off, wireless is disabled—contact your network administrator. For mobile devices, install a compatible HP printing app from the App Store or Google Play.

Important Safety Instructions

  • Always turn off the printer using the Power button and wait for the light to turn off completely to protect cartridges from drying out
  • Keep cartridges in their original sealed packaging until ready to install; leaving tape on cartridges reduces evaporation and extends shelf life
  • Clean cartridge electrical contacts (small gold dots) with a dry, lint-free cloth if you receive cartridge error messages; avoid touching the contact area with your fingers
  • Remove printed papers from the output tray frequently to prevent paper jams and ensure the paper-width guide sits snugly against your loaded paper
  • Check estimated ink levels regularly using the control panel display or HP Utility; keep replacement HP 65/65XL cartridges available to avoid printing delays
