Hi, I have a problem with print quality. I have installed a new cartridge, aligned it, and cleaned the nozzles several times along with the roller and glass panel. Still the print quality is patchy. Please help??!!
I'm not familiar with this unit. Make sure you are using the original cartridges and not "compatibles." They claim to be the same but they are not. There are some that are fine but their consistency changes all the time. If you are using the right cartridges then it may be the head that's clogged. The head in your unit may or may not be replaceable. If it's a bad clog, the cleaning process will not help. Manually cleaning these nozzles is not recommended because they can be damaged easily.

generally speaking this is a cartridge problem - some nozzles are clogged - U need to find tools in the printer menu then find clean printhead and run the process and print the test page or print quality page. and keep doing it 2 or 3 times untill the quality is OK - If still no good after all of this U can try soaking the printhead in 1/4" of warm water for 15 minutes and try again - if you are using original HP cartridges you are pretty much done at this point - if you are using refilled or aftermarket cartridges try replacing the black cartridge (I am assuming this is giving you the problem described) with a new HP (buy the small one just in case it still doesnt work) oif you have a cartridge refill place nearby U cant check and see if they can physically clean the printhead for you but results are not always good
Gently clean the contacts in the carriage, and on the cartridges with a paper towel or coffee filter moistened with water.
For the poor print quality or missing print:
Perform the Blot Test
Remove cartridge from machine, fold a paper towel back over a couple of times so it is about 4 layers thick, shake cartridge up and down hard, shake it over a sink unless you want to clean ink off the floor.
Now blot the nozzles of the cartridge on the paper towel, for a black cartridge you should see two black stripes, for a color cartridge you should see three colored stripes, if you don't have all stripes the cartridge is clogged or bad.
Have you checked the expiration date on the cartridges you are using?
Are you installing new HP cartridges, or refills? You may be able to recover a clogged cartridge by swishing the tip in a saucer with a very small amount of warm water, then gently wiping it on a wet paper towel, be gentle the nozzles are delicate. And do not trust the ink gauge on the PC, cartridges can dry up from the machine just sitting, the cartridges are vented, venting is necessary to let air in so that a vacuum won't develop in the cartridge.
New cartridge wouldnt print but sounded like it was printing. You can check ink levels clean or align cartridge by pushing menu then tools. I cleaned contact points w qtip and alcohol. What seemed to work is putting alcohol on cartridge where ink is released and putting back into machine wet did this three times first time little dots of ink then a faint print and now it is printing must have been dried ink further then I could access.
There is a Fax in memory. Either, the machine has a paper jam, is out of paper, or needs the ink cartridge replaced. Fix the above and the fax will print and the machine should work in Fax mode again.
For a unit with paper and no paper jam, try adjusting the paper stack and check if the unit picks up the paper properly. If you have ink in the cartridge, try cleaning the print nozzles and contacts. If a nozzle cleaning from the unit doesn't work, do it manually. Use a damp cloth (lint-free) and wipe in one direction only. Dampen the cloth with bottled or distilled water for best results. See your manual for pictures.
Are the problem prints all from the same source? If so the problem could be on the transmission end. Can you connect to your fax and print to it from a local workstation? If so print several images with dark solid patterns and see if it is actually the printhead. Try printing in cyan, magenta, yellow, and black colors to to rule out each individual printhead.
