1. Load plain white paper in the tray.

Very low ink levels, using non-HP cartridges, and rough handling can cause print quality issues.

1. Replace any non-HP or refilled cartridges with genuine HP cartridges. HP supplies are available from the HP Store and local retailers.

   HP cannot guarantee the quality or reliability of non-HP or refilled cartridges. Go to HP Anti Counterfeiting and Fraud Program for more information.

2. Check the ink levels and replace any low or empty cartridges.

   Note:

   The printer features a 'backup mode' that enables printing with one cartridge. Remove the low or empty cartridge to continue printing if a replacement is not available. Depending on the cartridge removed, blacks will not be as dark and color prints will be in grayscale.

   

3. Rough handling of cartridges during transport or installation can cause print quality problems. Wait a few hours for the automatic servicing routine to complete, and then try to print again.

   If you have a defective HP cartridge, it might be under warranty. Go to About Original HP Cartridges for page yield and HP limited warranty information.

Make sure your print job is set up for optimal print quality results.

1. Check the paper type and condition: Make sure the paper is appropriate for the print job and in good condition.

   • Some paper might not absorb ink as well as others, causing faded or smeared prints. Plain paper with ColorLok technology works well for text and documents with graphics. For photos, use HP Advanced Photo Paper for best results.

   • Use clean, wrinkle-free paper. Wrinkled or curled paper can cause dark, horizontal defects.

2. Load paper according to the print side: Typically, the smoother or glossy side is the print side.

   • For inkjet printers with a rear load tray, load the print side facing up.

   • For inkjet printers with a front load tray, load the print side facing down.

3. Check the print job settings: From the application you are printing from, click File > Print, and then click Options, Printer Setup, or Preferences, or open the Paper Type/Quality or Media & Quality menu.

   Make sure the color, paper type, paper size, and quality settings are correct for your print job.

4. Check the quality of the photo or document: Use editing tools to improve colors, brightness, contrast, and any other appearance settings. Higher resolution photographs and graphics result in clearer prints with more accurate colors.

Align the printheads or cartridges in your printer when you replace them, to improve print quality, or to clear an alignment error.

1. Load plain white paper in the input tray.

2. Open the HP Smart app, and then click the picture of your printer to open the settings and management tools.

3. In Print Quality Tools or in Advanced Settings > Tools > Utilities > Print Quality Toolbox, select Align or Align Printheads to start the alignment.

Remove any debris or buildup from the contacts on the cartridges and in the carriage.

1. Lift the cartridge access lid using the recessed areas on the sides of the printer.

   

2. Open the cartridge latch, and then pull the cartridge up and out of the slot.

   

3. Holding the cartridge by the sides, remove any protective tape that still might be on the contacts.

   CAUTION:

   Do not touch the ink nozzles or the copper-colored electrical strip. Touching or trying to remove these parts can result in clogs, ink failure, and bad electrical connections.

   

4. Lightly dampen a lint-free cloth with distilled water, and then wipe the copper-colored contacts on the cartridge.

   

5. Lightly dampen a lint-free cloth or swab with distilled water, and then clean the electrical contacts in the carriage.

   

6. Wait 10 minutes for the contacts to dry, and then reinsert the cartridge into its color-coded slot.

7. Repeat these steps for the other cartridge if it was indicated in the error message.

8. Close the lid to the cartridge access area.

   If the error persists, clean the cartridge and carriage contacts a second time.
