Replacing the Ink Cartridges for Deskjet 6940 and 6980 Printer Series

This document is for the HP Deskjet 6940, 6943, 6980, 6983, and 6988 printers
Follow the steps below to remove, replace, or maintain the print cartridges.
Step 1: Open the printer
If the HP Deskjet printer is turned off when the print-cartridge access door is lifted to access the print cartridges, the printer will not release the cartridges for changing. Damage may occur to the HP Deskjet printer if the print cartridges are not docked safely on the right side when you try to remove them. Push the scraper bar gently with your finger if it is blocking the cartridges, then press the Power button.
  1. Turn on the printer. Press the Power button if it is not lit.
  2. Open the printer cover, then wait until the print cartridge cradle moves to the right side of the printer and is idle and silent.

Print cartridge maintenance
After removing the print cartridges from the printer, it is necessary to follow basic care and maintenance guidelines to keep them from drying out. The following guidelines will help maintain HP inkjet print cartridges and ensure consistent print quality.
  • Do not reattach the plastic tape that covered the ink nozzles since this can damage the nozzles.
  • Store the print cartridge(s) in a print cartridge protector or airtight plastic container. If the cartridge is stored in an airtight plastic container, make sure the nozzles face down and are not in contact with the container. Do not use plastic bags: this may damage the print cartridges.
  • Placing a moist paper towel in the airtight container may help to keep the cartridges from drying out.
  • A print cartridge protector is provided with the photo print cartridge.
    • To insert the cartridge into this protector, slide the cartridge at a slight angle into the protector and snap it securely in place.
    • To remove the cartridge, press down and back on the top of the protector to release the cartridge. Slide the cartridge out of the protector.
  • Do not drop the print cartridge since it could be damaged.
