Troubleshooting FAQ

Printer Won't Print or Is Not Respondingexpand_more
Ensure the printer is powered on and paper is loaded in the input tray. Check for error messages in the HP printer software and follow the on-screen instructions. Verify the printer is set as the default printer in your Windows or macOS settings and that the print queue is not paused or offline. Restart the print spooler service if using Windows, or disconnect and reconnect the USB cable if applicable. Restart both the printer and the computer if the issue persists.
Paper Jam — How to Clearexpand_more
Start by removing all paper from the input tray and checking for jammed paper in the paper path using a flashlight. Press Cancel to attempt an automatic jam clear. If the jam is in the cartridge access area, open the door, turn off the printer, unplug the power cord, and carefully remove the jammed paper by hand using both hands gently. For jams underneath the printer, open the cleanout door on the bottom, remove the paper, and close the door until it latches. Reload paper and press the Resume button to continue.
Poor Print Quality or Streaky Outputexpand_more
First, confirm you are using genuine HP 65 or HP 65XL cartridges and that ink levels are not critically low. Check that the correct paper type and print quality settings are selected in the printer software. Open the HP printer software, click Print and Scan, then Maintain Your Printer, and use the 'Align Cartridges' tool to run an alignment. If streaks persist, run the 'Clean Cartridges' utility from the Device Services tab. For Mac users, open HP Utility and use the 'Clean Printheads' option.
Cartridge Error or Ink Alert Light Is Onexpand_more
If the Ink Alert light is on and an Ink Level icon is blinking, a cartridge may be missing, improperly installed, or still have plastic tape on the contacts. Open the cartridge access door, remove the indicated cartridge, verify the pull-tab tape has been fully removed, and reinsert it firmly until it clicks. If the error continues, clean the gold-colored electrical contacts on both the cartridge and inside the printer using a dry lint-free cloth. Replace the cartridge if the problem persists. Use genuine HP 65 cartridges for the DeskJet 2640.
Printer Not Connecting to Wireless Networkexpand_more
Press the Wireless button and the Information button simultaneously to print a Wireless Network Test Report and Network Configuration Page. Review the report for diagnostics on signal strength and detected networks. Make sure your wireless router is powered on and within range. If the Wireless Attention icon is blinking, the printer may be having trouble connecting — press the Wireless button to restart the wireless setup process. You can also use the HP Print and Scan Doctor utility on Windows to automatically diagnose and fix connection issues.

Important Safety Instructions

  • Always turn off the HP DeskJet 2640 using the Power button and wait for the light to go out before unplugging — this prevents the HP 65 cartridge nozzles from drying out.
  • Check estimated ink levels regularly from the HP Smart app or printer software 'Estimated Levels' tab, and keep a replacement HP 65 or HP 65XL cartridge on hand to avoid printing delays.
  • Do not open or remove the plastic tape from new HP 65 cartridges until you are ready to install them, as exposure to air accelerates ink evaporation.
  • Run the cartridge alignment tool from the HP printer software after installing new cartridges to ensure the best possible print quality on your DeskJet 2640.
