Copy function problem

The color of copied material is very light, almost hard to read. But the printout works fine, because it is new cartridge. Is there ant internal lamp or other stuff may damaged? The contrast is set up to high, and the quality is set to be photo.

HP Officejet 5610 All-In-One. cartridge error: refer to device documentation to troubleshoot ... I was in the process of of printing a series of documents. does not print prpoperly

Will it color copy- stand alone? Try making a copy on the printer by itself. If the copy is still printing in blue, then go to the service section in the menus, and clean the print head, if that does not work then try the recalibrate function. -If the copy comes out fine when you try it stand alone, try deleting the printer and reinstalling the printer.

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): (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. (HP 60 - Deskjet F2400/F4400/F4500 models) (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.

Either you purchased a a bad quality remanufactured toner cartridge or your fuser film is damaged.

If there is some kind of debris in black color that is on printouts, your fuser film might be damaged. Have a printer technician replace it.

If there is no debris, only bad quality printouts, it's the toner cartridge that needs replacement.

When I change the black ink cartridge, the alignment page and instruction page are printing out fine. When I place the alignment page on the glass as instructed and press 'ENTER', the printer gives a...

I just had the same issue (align page not detected).

We had just re-installed the empty color cartridge back into the printer (long story but basically we knew we could only print B/W).

The align page printout had a lot of empty spaces around the black lines. This is apparently where the color lines are supposed to print.

Without those color lines, the printer would not detect the align page as color is part of the alignment being done.

Since we only wanted black printouts, I pressed 'cancel' to stop the alignment process, and now we just hit the Black copy button and ignore the alignment prompt on the printer window.

The HP site (enter psc750 in product window) has some helpful ideas as to what the problem might also be. It could be the shipping tape is still on the new cartridge (and preventing the black or color from printing on the align sheets) etc.

Light in color and won't copy dark. It come out light purple

you may try
1) color ink cartridge--- no enough ink or the cartridge ink channel dryer and constipated, refill ink and put down the cartridge bottom surface to water a little for 1 hr, then set back. or change a new cartridge if not fixed go next
2) print head--- the ink channel dryer and constipated, take out print head clean it's ink channel using cleaner or steep in water (do not touch circuit pin area with water) 20 minutes or longer. then set back and test (you can do more times), still not fixed, your print head have to change.

Copies are very dark; almost grey.

Is this a color copier? If so are you using the color copier setting? If you are it is coping the color of the paper and it is comming out gray. Not sure but I have had this happen before.

the message of low ink cartrige always appears after refilling the cartridge or installing the recycled cartridge.only if u install orignal cartridge it will go.but let it show low ink you will get proper printouts till the end of the cartridge as this message does not effect on copy quality or number of printouts.the printer will work.just cancel that message or will not effect your printer.
