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 and Declaration of Conformity for voltage requirements.
Check printer vents
The printer vents are located on the sides of the  printer. If the vents are covered and the printer
overheats, the printer automatically turns off. Make sure the  vents are not covered and the printer is
in a cool, dry location. See 
Printer specifications and Declaration of Conformity  for the required
operating environment for the printer.
All printer lights are blinking
A non-recoverable error has occurred.
Reset the printer. See To reset the printer .

Customer support and warranty .
Printer is not responding (nothing prints)
Check printer setup
See Troubleshooting tips and resources .
Check the print cartridge initialization
When print cartridges are installed or replaced, the printer automatically prints an alignment page to
align the print cartridges. This process takes about  seven minutes. Until this process is complete,
only the automatic alignment page can be printed.
Check the printer software installation
Make sure the printer is connected firmly to a functioning alternating current (AC) power outlet and is
turned on. See 
Printer specifications and Declaration of Conformity  for voltage requirements.
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:
■ 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 driver and printer driver 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 
Connecting to a network .
Printer does not accept a print cartridge
Print cartridge does not fit the printer
Verify that the print cartridge is in the correct  print cartridge cradle. The symbol on the print cartridge
and the print cartridge latch should match.
Printer does not recognize the print cartridge
Verify that the nozzle protective tape has been removed from the cartrid\
ge and that the cartridge is
properly installed with the latch closed. See 
Installing or replacing the print cartridges .
Clean the print cartridge contacts
Complete the print cartridge cleaning procedure. See Cleaning the print cartridges.
Remove the print cartridge and ensure the print cartridge  latch is closed. Turn off the printer without
the print cartridge installed. Restart the printer and reinsert the print cartridge (see 
Installing or
replacing the print cartridges ).

Check the print location and length of USB cable
High electromagnetic fields (such as those generated by USB cables) can sometimes slightly distort
printouts. Move the printer away from the source of the electromagnetic fields. Also, it is
recommended that you use a USB cable that is less than 3 meters (9.8 feet) long to minimize the
effects of these electromagnetic fields.
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. See 
Loading media in the input tray .
Check the media size
■ Content on a page might be cut off if the document  size is larger than the media that you are
