Print quality is poor.

Solution

●

You may be printing in Ink-backup Printing Mode. The printer enters Ink-
backup Printing Mode when one of the print cartridges is missing. Replace
the missing print cartridge with a new one.

●

One of the print cartridges may be running out of ink. Check to see if the print
cartridge status indicator appears on the printer screen. If a print cartridge
is running low on ink, replace it. For more information, see

●

Use photo paper designed for the printer. For best results, use HP paper.

●

You may be printing on the wrong side of the paper. Make sure the paper is
loaded with the side to be printed facing down.

●

You may have selected a low-resolution setting on the digital camera.
Reduce the size of the image and try printing again. For better results in the
future, set the digital camera to a higher photo resolution.
