Press the Resume button to continue printing. For jams in the cartridge access area, turn off the printer, open the access door, move the carriage to the right, remove the jammed paper, and restart.
Cartridge or Ink Detection Errorexpand_more
Check that the plastic protective tape has been completely removed from each cartridge. Verify cartridges are inserted in the correct color-matched slots and fully clicked into place. If the Ink Alert light remains on, remove the cartridge, clean the electrical contacts with a dry lint-free cloth, and reinstall. Replace cartridges if contacts are damaged or if the error persists.
Printer Not Printing or Respondingexpand_more
Verify the printer is powered on and paper is loaded in the input tray. Disconnect and reconnect the USB cable if using wired connection, or confirm wireless connection status using the Wireless button and control panel display. Check that the printer is not paused or offline in Windows Devices and Printers. Verify the printer is set as the default printer. Restart the print spooler service and clear the print queue if necessary. The HP Print and Scan Doctor utility can automatically diagnose and resolve most issues.
Poor Print Quality or Faded Outputexpand_more
Use original HP cartridges and verify they have sufficient ink levels using the control panel display or printer software. Check that you've selected the correct paper type and quality settings in the printer software. Ensure paper is flat and of high quality—HP recommends papers with ColorLok certification. Align the cartridges by accessing the printer software's maintenance tools. Print a diagnostic page to check for streaks or missing color sections, then clean the cartridges if needed.
Wireless Connection Issuesexpand_more
Press the Wireless button and Information button simultaneously to print the wireless network test report. Verify your wireless router is powered on and the printer is within range. Check the Wireless light status—if blinking with attention icon, move the printer closer to the router. If the light blinks and then turns off, wireless capabilities are disabled; access the embedded web server to adjust wireless settings. Update your network password or reconnect if the network credentials have changed. Use the HP Print and Scan Doctor for automatic diagnosis.
