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. See Troubleshooting. If the problem persists, contact HP. See Support and warranty.
Printer is not responding (nothing prints)
Check printer setup See General troubleshooting tips. Check the printhead initialization When new printheads are installed, the printer automatically prints two alignment pages to align the printheads. This process takes about eight minutes. Once the process starts you cannot print until the automatic alignment pages have been printed. When printheads are removed and then reinserted in the printer, the alignment pages do not print automatically. See To align the printheads. Check the printer software installation If the printer is turned off when printing, an alert message should appear on your computer screen; otherwise, the printer software might not be installed correctly. To resolve this, uninstall the software completely, and then reinstall the printer software. See Uninstalling the printer software. Check cable connections Make sure both ends of the cable (USB, parallel, or network) are secure. If the printer is connected to a network, check the following: Verify that the Link light on the back of the printer is on. Make sure you are not using a phone cord to connect the printer. The network hub, switch, or router is on and working properly.
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. However, the firewall might block communication between the computer and the printer. If there is a problem communicating with the printer, try temporarily disabling the firewall. If the problem persists, the firewall is not the source of the communication problem. Re-enable the firewall. If disabling the firewall allows you to communicate with the printer, you might want to assign the printer a static IP address and re-enable the firewall. See Configure network options.

Colors are printing as black and white
Make sure Print in Grayscale is not selected in the printer driver.
Wrong colors are printing
Check print settings Make sure Print in Grayscale is not selected in the printer driver. Check the printheads Whenever print quality noticeably decreases, you might need to clean the printheads. See Maintaining the printheads.
Printout shows bleeding colors
Check print settings Some media type settings (such as Transparency Films and Photo Papers) and print quality settings (such as Best) require more ink than others. When you choose different print settings in the printer driver, make sure you select the correct media type. See Changing print settings.
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. However, you might notice improvement in the print quality by performing the alignment procedure yourself. See Maintaining the printheads. Check graphics placement Use the zoom or print preview feature of your software to check for gaps in the placement of graphics on the page.
Lines or dots are missing from text or graphics
The printheads or printhead contact pads might need cleaning. See Maintaining the printheads.
Resolving paper-feed problems
For information on resolving jams, see Clearing jams.
Media is not supported for the printer or tray
Use only media that is supported for the printer and the tray being used. See Understanding specifications for supported media.
Media is not picked up from the tray
Make sure the paper guides are set to the correct markings in the tray for the media size you are loading. Also make sure the guides are snug, but not tight, against the stack. Make sure media in the tray is not curled. Uncurl paper by bending it in the opposite direction of the curl. Also, check the ink saturation. To increase the ink drying time and reduce the ink saturation, use an ink slider in conjunction with drying time under Advanced Printing Features (Windows) or Ink Features (Mac OS) in the printer software. However, note that decreasing ink saturation might give printouts a "washed-out" quality.
Media is not coming out correctly
Make sure the output tray extension is extended, otherwise, printed pages might fall off the printer. Remove excess media from the output tray. There is a limit to the number of sheets the tray can hold.
