    note:
    You might also find instructions in the printer's user guide. From the printer support page, click User guides, and then click the user guide to open and view it.
  • If the Network Configuration Page prints normally, but you are still experiencing print quality issues, go to the solution to check the USB connection.
  • If the Network Configuration Page contains garbled, illogical text, or is missing text or graphics, continue to the next solution.

Solution two: Check the print cartridges

  caution:
To prevent damage to a print cartridge, do not expose it to light for more than a few minutes.

Step 1: Make sure that the print cartridges are genuine HP print cartridges

Check the print cartridges to see if they have HP on them. Genuine HP print cartridges are always printed with HP, Hewlett-Packard, or the HP logo ().
note:
Hewlett-Packard Company cannot recommend the use of non-HP print cartridges, either refilled, new, or remanufactured. Any damage caused by a non-HP print cartridge is not covered under the HP warranty and service agreements. Go to HP LaserJet Print Cartridges and Imaging Drums Limited Warranty Statement (in English).
  • If all the print cartridges are genuine HP print cartridges, see the next step.
  • If one or more of the print cartridges are not genuine HP print cartridges, replace them.

Step 2: Check the print cartridges for sealing tape and any damage

  1. Open the print cartridge door completely.
  2. Pull out the print cartridge drawer completely, if your printer has one.
  3. To each print cartridge, grasp the handle, and then pull straight out to remove it.
  4. If the print cartridge seal is in place, remove it. Pull the tab on the end of the print cartridge to remove the entire length of the seal.

      • Very dry (low humidity) conditions can increase the amount of background shading.
      • Very wet (high humidity) conditions can fog up the laser scanner optics, cause drop-outs, cause uneven dark, light or fuzzy print, or leave water droplets on the printed page.
    • Move the printer from confined spaces such as a cabinet.
    • Remove anything blocking the top vents. Make sure that air flows freely around the printer, including the top.
    • Protect the printer from airborne debris, steam, grease, or other elements that can leave residue inside the printer.
