Solve printer problems TIP: You can visit the HP online support website at www.hp.com/support for information and utilities that can help you correct many common printer problems.
Chapter 5 Check the HP software installation If the printer is turned off when printing, an alert message should appear on your computer screen; otherwise, the HP software provided with the printer might not be installed correctly. To resolve this, uninstall the HP software completely, and then reinstall the HP software. For more information, see Uninstall and reinstall the HP software. Check the cable connections • Make sure both ends of the USB cable or Ethernet cable are secure.
NOTE: The printer can operate with one or more depleted cartridges. However, printing with depleted cartridges slows the printer and affects the quality of printed documents. If the black cartridge is depleted, blacks are not as dark. If a color cartridge is depleted, output is in grayscale. When possible, replace the depleted cartridge. Do not remove the depleted cartridge until you have a new ink cartridge available. For information about how to install new cartridges, see Replace the ink cartridges.
Chapter 5 Blank or partial page printed Clean the printhead Complete the printhead cleaning procedure. For more information, see Clean the printhead. The printhead may need to be cleaned if the printer was turned off incorrectly. NOTE: Incorrectly turning off the printer can cause print quality problems like blank or partial pages. Printhead cleaning can solve these problems, but turning off the printer correctly can prevent them in the first place.
Placement of the text or graphics is wrong Check how the media is loaded Make sure the media width and length guides fit snugly against the edges of the stack of media, and make sure the tray is not overloaded. For more information, see Load paper. Check the media size • Content on a page might be cut off if the document size is larger than the media that you are using. • Make sure the media size selected in the printer driver match the size of media loaded in the tray.
Chapter 5 Solution 1: Make sure you are using genuine HP ink cartridges Solution: Check to see if your ink cartridges are genuine HP ink cartridges. HP recommends that you use genuine HP ink cartridges. Genuine HP ink cartridges are designed and tested with HP printers to help you easily produce great results, time after time. NOTE: HP cannot guarantee the quality or reliability of non-HP supplies. Printer service or repairs required as a result of using a non-HP supply are not covered under warranty.
Solution 3: Check the paper loaded in the input tray Solution: Make sure the paper is loaded correctly and that it is not wrinkled or too thick. • Load paper with the print side facing down. For example, if you are loading glossy photo paper, load the paper with the glossy side down. • Make sure the paper lays flat in the input tray and is not wrinkled. If the paper is too close to the printhead during printing, the ink might be smeared.
Chapter 5 Solution 5: Check the print settings Solution: Check the print settings. • Check the print settings to see if the color settings are incorrect. For example, check to see if the document is set to print in grayscale. Or, check to see if advanced color settings such as saturation, brightness, or color tone, are set to modify the appearance of colors. • Check the print quality setting and make sure it matches the type of paper loaded in the printer.
If defects are seen on the Print Quality Diagnostic report, follow the steps below: 1. If the Print Quality Diagnostic report shows faded, partial, streaked, or missing color bars or patterns, check for depleted ink cartridges, and replace the ink cartridge that corresponds to the defective color bar or color pattern. If there is no depleted ink cartridge, remove and reinstall all ink cartridges to make sure they are properly installed.

E 136 How do I? • Get started • • Print Work with ink cartridges • Solve a problem How do I?
F Errors (Windows) Printer disconnected The computer cannot communicate with the printer because one of the following events has occurred: • The printer has been turned off. • The cable connecting the printer, such as a USB cable or a network (Ethernet) cable, has been disconnected. • If the printer is connected to a wireless network, the wireless connection has been broken.
Appendix F To solve this problem, try the following solutions. Solutions are listed in order, with the most likely solution first. If the first solution does not solve the problem, continue trying the remaining solutions until the issue is resolved. • Solution 1: Turn the printer off and on. • Solution 2: Install the ink cartridges correctly. • • Solution 3: Clean the electrical contacts. Solution 4: Replace the ink cartridge.
The cartridge cradle cannot move Something is blocking the ink cartridge cradle (the part of the printer that holds the ink cartridges). To clear the obstruction, press (Power button) to turn off the printer, and then check the printer for jams. For more information, see Clear jams. Paper Jam Paper has become jammed in the printer. Before you try to clear the jam, check the following: • Make sure that you have loaded paper that meets specifications and is not wrinkled, folded, or damaged.
Appendix F Ink cartridge failure The cartridges listed in the message are damaged or have failed. See Replace the ink cartridges. Printer supply upgrade problem The supply upgrade was not successful. The cartridges listed in the message can still be used in this printer. Replace the Supply Upgrade cartridge. For more information, see Replace the ink cartridges. Counterfeit Cartridge Advisory The installed cartridge is not a new, genuine HP cartridge. Contact the store where this cartridge was purchased.
Solution: Click OK to continue printing or replace the cartridge. For information about how to install new cartridges, see Replace the ink cartridges. Problem with printer preparation The printer clock has failed and ink preparation may not be complete. The estimated Ink Level gauge might be inaccurate.
