Selecting print media The printer is designed to work well with most types of office paper. It is best to test a variety of print media types before buying large quantities. Use HP media for optimum print quality. See HP supplies and accessories. For more information about HP media, see www.hp.com. Tips for selecting and using print media For the best results, observe the following guidelines. ● Always use media that conforms to the printer specifications.
Transparencies ● Insert transparencies with the rough side down and the adhesive strip pointing towards the back of the printer. ● Use the Best mode to print transparencies. This mode provides longer drying time and ensures that the ink dries completely before the next page is delivered to the output tray. Allowing wet media to stack up might cause smearing. Custom-size media ● Use only custom-size media supported by the printer.

Wait about 10 seconds, and then reconnect the power cord. 4. Press (Power button) to turn on the printer.
● If the printer is connected directly to a computer, it is set up to point to the correct port. ● If the printer is connected to a network, the correct IP address is used. Resolving printing problems Printer shuts down unexpectedly Check power and power connections. Make sure the printer is connected firmly to a functioning alternating current (AC) power outlet. See Printer specifications for voltage requirements. All printer lights are blinking A non-recoverable error has occurred. Reset the printer.
Check printer setup for network environment Ensure the correct printer software and printer software port are being used. For more information about network connections, see Configuring the printer (Windows), Configuring the printer (Mac OS), or the documentation provided by your network vendors. Check any personal firewall software installed on the computer The personal software firewall is a security program that protects a computer from intrusion.
Check media settings Make sure the page settings in the printer software matches the width and length of media loaded in the tray. See Changing print settings. Check the parallel port on your computer If you are using a parallel cable, make sure the printer is connected directly to the parallel port. Avoid sharing the port with other devices, such as a Zip drive or other printers.
Poor print quality and unexpected printouts Check the printheads and ink cartridges Replace any clogged or worn printheads or low ink cartridges (see Maintaining the printheads), and try to print again. Check the paper quality The paper might be too moist or too rough. Make sure the media used meets HP specifications (see Selecting print media), and try to print again. Check the type of media loaded in the printer ● Make sure the tray supports the type of media you have loaded.
Check print settings ● When you print documents that use a large quantity of ink, allow more time to dry before handling the printouts. This is especially true for transparencies. In the printer software, select the Best print quality. Also increase the ink drying time and reduce the ink saturation using an ink slider in conjunction with drying time under Advanced Printing Features (Windows) or Ink Features (Mac OS) in the printer software.
Clean the print zone of the printer After extensive printing, ink might be deposited on the print zone of the printer, causing ink to smear on the non-printed side of the media or the edge of a stack of printed media. To remove the deposited ink, use a lint free cloth to clean the print zone, including the plastic ridges.
Ink is not filling the text or graphics completely Check the ink cartridges Ink cartridges might have run out of ink. Replace any empty cartridge. Or try removing and reinstalling the cartridges, make sure they snap firmly into place. See Replacing the ink cartridges. Check the media type Some media types are not suitable for use with the printer. See Selecting print media. Output is faded or dull colored Check the print mode The Fast Normal printer mode allows you to print at a faster rate.
Check ink cartridges Make sure ink cartridges have not been tampered with. Refilling processes and the use of incompatible inks can disrupt the intricate printing system and result in reduced print quality and damage to the printer. HP does not guarantee or support refilled ink cartridges. For ordering information, see HP supplies and accessories. Colors do not line up properly Check printheads The printheads are not automatically aligned when a printhead is replaced.
Pages are skewing ● Make sure the paper guides in the tray are adjusted snugly against the media, but do not crinkle or bend it. ● Avoid loading media of different types or sizes in the tray. ● Make sure media in the tray is not curled. Uncurl paper by bending it in the opposite direction of the curl. ● Run a media skew test in the Toolbox. See Testing media skew.
Troubleshooting installation issues Problems printing alignment page When new printheads are installed, the printer automatically prints two alignment pages to align the printheads. This process takes about eight minutes. Do not open any covers or push any buttons until the alignment pages have printed. The alignment pages may be discarded after they are printed. If the printer does not print the pages, then see General troubleshooting tips or align the printheads manually (see To align the printheads).
