							cartridge available to avoid possible printing delays. You do not need to replace the 
print cartridges until print quality becomes unacceptable. 
If you have installed a refilled or remanufactured cartridge, or a cartridge that has 
been used in another product, the ink level indicator may be inaccurate or unavailable. 
For HP product return and recycl ing information, visit us at: www.hp.com/recycle. 
Cause: The indicated print cartridges were estimated to be low on ink and might 
need to be replaced soon.
Printing in ink-backup mode 
Solution: If you receive the ink-backup mode message and two print cartridges are 
installed in the product, verify that the protective piece of plastic tape has been 
removed from each print cartridge. When plastic tape covers the print cartridge
contacts, the product cannot detect that the print cartridge is installed.
1Copper-colored contacts
2Plastic tape with pink pull tab (must be removed before installing)
3Ink nozzles under tape
For more information, see  “Use ink-backup mode” on page 72. 
Cause: When the product detected that only one print cartridge is installed, ink- 
backup mode is initiated. This printing mode lets you print with a single print cartridge, 
but it slows the product and affects the quality of printouts.

Try the following solutions to resolve the issue. 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.

Troubleshooting
 
						

							Solution 1: Print a self-test report 
Solution: Print a self-test report to see if the product can print. 
To print a self-test report 
1. Load letter or A4 unused plain white paper into the input tray.

complete. 
• If more than a few lines in a pattern are broken, this might indicate a problem 
with the nozzles. You might need to clean the print cartridges. 
• If the black line is missing, faded, streaked, or shows lines, this might indicate 
a problem with the black print cartridge in the right slot. 
• If any of the color lines are missing, faded, streaked, or show lines, this might 
indicate a problem with the tri-color print cartridge in the left slot.
