• Remove printed papers from the output tray frequently.
• Ensure that paper loaded in the input tray lays flat, and the edges are not bent or torn.
• Do not combine different paper types and paper sizes in the input tray; the entire stack of paper in the input tray must be the same size and type.
• Adjust the paper-width guide in the input tray to fit snugly against all paper. Make sure the paper-width guide does not bend the paper in the input tray.
• Do not force paper too far down in the input tray.
• Do not add paper while the printer is printing. If the printer is about to run out of paper, wait until the out of paper message appears before adding paper.

What kind of problem are you having?

• Paper is not picked up from the input tray
  • Make sure paper is loaded in the input tray. For more information, see Load media on page 15.

Ink cartridge issues

Identify whether an ink cartridge has a problem

To identify whether an ink cartridge has a problem, check the status of the Ink Alert light and the corresponding Ink Level icon. For more information, see Control panel lights and display icons status on page 7.

If you get an ink cartridge problem message from the printer software that states at least one of the cartridges has a problem, do the following to identify whether a cartridge has a problem.

1. Remove the black cartridge and then close the cartridge access door.

• If the Ink Level icon for the tri-color cartridge blinks, the tri-color cartridge has a problem.
• If the Ink Level icon for the tri-color cartridge does not blink, the tri-color cartridge does not have a problem.

2. Install the black cartridge back in the printer, remove tri-color cartridge, and then close the cartridge access door.

• If the Ink Level icon for the black cartridge blinks, the black cartridge has a problem.
• If the Ink Level icon for the black cartridge does not blink, the black cartridge does not have a problem.

Fix ink cartridge problems

If an error occurs after a cartridge is installed, or if a message indicates a cartridge problem, try removing the ink cartridges, verifying the protective piece of plastic tape has been removed from each ink cartridge, and then reinserting the ink cartridges. If this does not work, clean the cartridge contacts. If the problem is still not resolved, replace the ink cartridges. For information about replacing ink cartridges, see Replace ink cartridges on page 58.

To clean cartridge contacts

CAUTION: The cleaning procedure should take only a few minutes. Make sure that the ink cartridges are reinstalled in the printer as soon as possible. It is not recommended to leave the ink cartridges outside of the printer longer than 30 minutes. This could result in damage to the printhead or the ink cartridges.

1. Check that power is on.

2. Close the output tray extender, and then rotate the output tray clockwise to stow it in the printer.

3. Open the front door of the printer.

4. Open the cartridge access door and wait for the print carriage to move to the center of the printer.

5. Remove the ink cartridge indicated in the error message.

6. Clean the cartridge contacts and printer contacts.

• Hold the ink cartridge by its sides with the bottom pointing up and locate the electrical contacts on the ink cartridge.

  The electrical contacts are the small gold-colored dots on the ink cartridge.

• Wipe only the contacts with a dry swab or lint-free cloth.

CAUTION: Be careful to wipe only the contacts, and do not smear any of the ink or other debris elsewhere on the ink cartridge.

• On the inside of the printer, locate the contacts for the cartridge.

  The printer contacts are the set of gold-colored bumps positioned to meet the contacts on the ink cartridge.

• Use a dry swab or lint-free cloth to wipe the contacts.

7. Reinstall the ink cartridge.

8. Close the cartridge access door, and then close the front door.

9. Check if the error message has gone away. If you still receive the error message, turn the printer off, and then on.

NOTE: If one ink cartridge is causing problems, you can remove it and use the single-cartridge mode to operate the printer with only one ink cartridge.

Fix ink cartridge incompatible issues

The ink cartridge is not compatible with your printer. This error can occur if you install an HP Instant Ink cartridge into a printer that has not been enrolled in the HP Instant Ink program. It can also occur if the HP Instant Ink cartridge was previously used in a different printer enrolled in the HP Instant Ink program.

Fix print quality issues

Read general instructions in the Help for resolving print quality issues

NOTE: To protect the cartridges from drying out, always turn the printer off using the Power button, and wait until the Power button light goes out.

To improve print quality (Windows)

1. Make sure you are using original HP ink cartridges.

2. Check the printer software to make sure you have selected the appropriate paper type from the Media drop-down list and print quality from the Quality Settings drop-down list.

In the printer software, click Print & Scan and then click Set Preferences to access the print properties.

3. Check the estimated ink levels to determine if the ink cartridges are low on ink.

For more information, see Check estimated ink levels on page 56. If the ink cartridges are low on ink consider replacing them.

4. Check the paper type.

For best print quality, use high quality HP paper, or papers that adhere to the ColorLok® standard. For more information, see Paper basics on page 21.

Always make sure the paper you are printing on is flat. For best results when printing images, use HP Advanced Photo Paper.

Store specialty paper in its original packaging inside a resealable plastic bag on a flat surface in a cool, dry place. When you are ready to print, remove only the paper you plan to use immediately. When you have finished printing, return any unused photo paper to the plastic bag. This prevents the photo paper from curling.

To improve print quality (OS X)

1. Make sure you are using original HP cartridges.

2. Make sure you have selected the appropriate paper type and print quality in the Print dialog.

3. Check the estimated ink levels to determine if the cartridges are low on ink.

Consider replacing the print cartridges if they are low on ink.

4. Check the paper type.

For best print quality, use high quality HP paper, or papers that adhere to the ColorLok® standard. For more information, see Paper basics on page 21.

Always make sure the paper you are printing on is flat. For best results when printing images, use HP Advanced Photo Paper.

Store specialty paper in its original packaging inside a resealable plastic bag on a flat surface in a cool, dry place. When you are ready to print, remove only the paper you plan to use immediately. When you have finished printing, return any unused photo paper to the plastic bag. This prevents the photo paper from curling.
