Image defects, no matter the cause, can often be resolved using the same steps. Use the following
steps as a starting point for solving image defect issues.
1. Reprint the document. Print quality defects can be intermittent in nature or can go away
completely with continued printing.
2. Check the condition of the cartridge or cartridges. If a cartridge is in a Very Low state (it has
passed the rated life), replace the cartridge.
3. Make sure that the driver and tray print mode settings match the media that is loaded in the tray.
Try using a different ream of media or a different tray. Try using a different print mode.
4. Make sure the printer is within the supported operating temperature/humidity range.
5. Make sure that the paper type, size, and weight are supported by the printer. See the printer
support page at support.hp.com for a list of the supported paper sizes and types for the printer.
NOTE: The term "fusing" refers to the part of the printing process where toner is affixed to paper.
The following examples depict letter-size paper that has passed through the printer with the short edge
first.

Sample Description Possible solutions
Dark or light lines which repeat down
the length of the page, and are wide-
pitch and/or impulse bands. They might
be sharp or soft in nature. The defect
displays only in areas of fill, not in text or
sections with no printed content.
1. Reprint the document.
2. Try printing from another tray.
3. Replace the cartridge.
4. Use a different paper type.
5. Enterprise models only: From the
Home screen on the printer control
panel, go to the Adjust Paper Types
menu, and then choose a print
mode that is designed for a slightly
heavier media than what you are
using. This slows the print speed
and might improve the print quality.
6. If the issue persists, go to
support.hp.com.
