Getting blue horizontal lines through all docs and photos. Just replaced both black and color cartridges.

Sounds like the print heads need cleaned, sometimes the software clean mode will not clean them good and you have to physically go in and clean them.

Vertical black lines:Check with another cartridge..Check Teflon sleeve.Vertical white lines:Replace cartridge.. replace transfer roller..Clean laser scanner unit( technical skills required) Horizontal Black lines:Replace cartridge..

First your white horizontal lines are due to you not printing in the best quality. Go into the printing preferences and change the quality to best/quality.

The dots printed vertically are possibly due to ink getting onto the star wheels on the doc exit rollers. Also its possible that the printing media is a bit on the thin side and may need to be supported when exiting the machine.

Those should solve your problem. A new printhead wont make any difference.

Good luck

22.6mm marks indicate a bad cartridge. Try a different cartridge if you have one.

Yes correct.The photo cartridge has to be inserted, where you install black cartridge.The photo cartridge gives finishing touch to the photos which you print.The actual photo comes from the color cartridge only, but for lightness and darkness, the color(ink) from photo cartridge gets used.In photo cartridge there are three color ink, that are light pink, light blue and grayish black.In color cartridge there are three color ink, that are pink(magenta), yellow and cyan( blue).------------- This are the details.Thank you for using fixya.

replace the both ink (black, colored)

In the past when I have seen this on my old printers, it is the color cartridge. Eithe the haed is cloged or it needs to be replaced. You could try to take the color cartridge and set the print head(copper colored end) on a damp towel for a little while and see if it will release the clog. (HP uses mostly water base inks and they dry out sometimes) Then wipe the head on a dry cloth. Reinstall and try again. You should also have software for HP to prime the head and clean it. Try that and if you still have problem, replace color cartridge.

Hi George,

It sound's like an ink-feed issue:

1) Dirty heads, even after cleaning
2) No-ink or poor quality ink
3) Damaged head: some are part of the cartridge, some are not
4) Air bubbles in ink

The test page is typically not as hi-res nor as saturated as a
photo print. The hi-res photo puts the greatest demand on the print head.

The color lines you see are actually lines of missing color,
where the head has failed to deposit ink, so one or two primary
colors are missing from the complete picture.

For example missing yellow will make a blue line.
Missing magenta will make a green line
Missing cyan will make a red line.... etc..

Clean the heads again and again, print again and again,
hoping to flush the system.

BUT, keep in mind that cleaning wastes huge amounts of
ink and tiny little cartridges of ink cost more than many new printers.

Replace the print head, and all should be just fine.

Hello we have had customers with this problem and this model printer We came upon this type of problem also exhibited the same lining when you did a nozzle check independant of the computer (not attached to computer and just using the internal head check print) This was a cartridge problem and after replacing the cartridge the problem stopped.
