To clear this problem you will have to run a deep cleaning of the nozzles using new OEM cartridges. If you have been using aftermarket or refilled (AM/R) cartridges, they have most likely gummed up the nozzles. The inks used in these AM/R cartridges vary in their quality and generally are marginal in meeting the manufacturer's specifications.
It will take a number of passes (at least 3 times) with the cleaning utility using OEM cartridges to clear the problem. You can get by for a while using AM/R cartridges, but you should keep the OEM cartridges around to clear clogged nozzles.
Let me know if this clears the problem.
Please rate this solution. Thanks.

Hp 4480 how do you unpause it


The HP F4480 likely has a malfunctioning ink cartridge which is causing the printer hang (i.e. internal micro-electronics damage inside the HP 60 color or black ink cartridge). You can verify the electrical condition of both HP 60 ink cartridges by activating the Tap 41 diagnostic test report (see video here for complete instructions):

http://inkjet411.com/?page_id=440 (HP 60 - Deskjet F2400/F4400/F4500 models)
    1.While holding the Power button, press Cancel (X) button 4 times, then press the Color Copy button once.
    2.Release the Power button.
    3.The 'Tap 41' diagnostic test print should print.

    Providing the color cartridge is partially functioning the Tap 41 diagnostic test print will be printed (this is a forced service print test which is mainly used for the evaluation of ink cartridge electrical health). A good HP 60/60XL color cartridge should display 1248 good nozzles, while a good HP 60/60XL black ink cartridge should show 336 good nozzles. If the results yield anything different then the ink cartridge is likely damaged and will need to be replaced. Refer to 2nd video on how to read the printout.
    http://inkjet411.com/?page_id=440 (HP 60 - Deskjet F2400/F4400/F4500 models)
    http://inkjet411.com/?page_id=444 (HP 60 - Deskjet F4200 model)

    If the printer attempts to print the diagnostic test pattern (1 page) then the printer is generally considered operational and functional, if nothing is printed, but the printer attempts to print the pattern, then the tri-color ink cartridge is either empty, clogged or severely electrically damaged (black ink cartridge is not used). You can remove the tri-color cartridge, reactivate the tap 41 test and the printer will print the diagnostic test print in black ink.

Cannot make the printer work after I changed the ink cartridges?


You can validate the HP60 ink cartridge's electrical health by running the 'Tap 41' diagnostics test (this procedure is specific to the F2480 model). Refer to DIAGNOSTIC TAP 41 video procedure at the following link on how to activate and read the service test: http://inkjet411.com/?page_id=440

1. While holding the Power button, press Cancel (X) button 4 times, then press the Color Copy button once.
2. Release the Power button.
3. The 'Tap 41' diagnostic test print should print.

Standard black printing has faded to grey.


Could just be a faulty cartridge?

My hp printer developed a similar fault, and despite all my attempts to clean, realign, whatever, the problem wasn't solved till I fitted a new ink cartridge. It's worth a try.

Print faded after replacing black cartridge Brother 240C


The print heads don't appreciate being out of ink so the Brother printer has sensors to prevent that but the tape defeated that prevention. Maybe more cleanings or maybe a cartridge with printhead cleaning solution will help. Otherwise, I fear a new printer.
