HP all-in-one not printing cyan color

HP L7680 all of a sudden stopped printing cyan. Replaced cartridge even though not completely empty and still no cyan. Went through all of the diagnostics that the printer has for alignment, cleaning, calibration. Self test diagnostic says print heads are good. Only 8700 prints on this printer and heads, any ideas?

    Are you talking about the ink cartdridge or the print head. Ink cartridge is new and previous ink cartridge was not yet all used. Could it be the print head going bad? I removed the print heads and cleaned manually. Expiration date on heads is 5/10/2010. Looks like it prints fine for the first 2.5 inches then fades. By the end of the print there are noticable lines perpendicular to the sheet feed. Any further recommendations? Thanks.

Place a soft clean tissue paper over the cartridge print head and leave for about eight minutes. You can secure it with the aid of a rubber band. It should be held firm ok. If the tissue paper is not dampened by ink then the cartridge would have gone bad or the ink dried. You also know that they have expiry date and could go bad while yet in the packaging b/c it has expired. Good luck

Alignment failed when run


If Printer heads health condition is not good, alignment wont completes..
Four individual cartridges & Two print heads, each print head prints two colors.. Black& Yellow, Cyan & Magenta.. Verify which color is not printing properly(Color missing Or white bands)..
Perform 2 or 3 times print head cleaning through printer menu..Try for alignment.. If success end.. if no, replace the print head which is not printing properly.. Before replacing the printer head ensure that cartridge ink should be above 30%...

Excess cyan toner is on electrostatic transfer sheet even after wiping it. All black and white pages are printed with cyan background.I am even using original cartridges.


Since you have Cyan toner in places where it should not be then the only possible cause is a defective Cyan Toner cartridge. I worked on one just last week where the customer complained about Magenta toner on their prints. I also noticed Magenta toner on the Transfer Belt just as you see Cyan toner on the Transfer Belt. I replaced the Magenta Toner Cartridge and everything cleared up nicely. The Transfer Belt Unit can also cause similar problems but it would not be ONLY one color like Cyan. It would be a mixture of all colors. My bet is replace the Cyan toner and you will be fine. If you have an old empty one just shake it up a bit and try it as well. This might allow you to verify before buying a new cartridge.
Good Luck and Thank You for using Fixya.

Will PIXMA MP640 print with an empty cartridge


No, it will not. I have this printer and last week I ran out of cyan. Even though i only wanted to print black and white documents the printer would not print anything until I replaced the cyan cartridge.

My printer has two cartriges that are empty would that prevent it from printing ?


Yes the HP CLJ 2600n printer will stop printing when a toner cartridge registers as empty. The cartridges will have to be replaced or You could use the "overide out" option. This allows continued printing even though the supply registers as empty. Beware that diagnosing print quality problems because of toner becomes more difficult.

Overide Out
To change this go to the PRINT QUALITY menu then REPLACE SUPPLIES and change the setting from "stop at out" to "overide out".

My HP OfficeJet L7680 just stopped printing ANYTHING black. I change the black cartridge twice.I cleaned the printer heads, aligned it and still it will no longer print anyhting in black. When I do a test...


It sounds like your printer setup has changed to generating black by MIXING the color inks... if you run out of the cyan and yellow it will do red in spite of how many changes you make of the black cartridge.

Investigate the setup for the printer to make sure it is set for black from the black cartridge.

What does cyan mean on a brother 240-c all in 1 printer it says replace cyan it wont do nothing


Cyan is the "blue/green" ink cartridge which is required to print in full color. Some printers stop working when one or more ink cartridges is empty. Get a complete set for some savings and for the next cartridge that gets empty. Printers are cheap now, it's the ink that gets costly.

C7180 Print in color without all cartridges


You can usually print with an empty cartridge, even though the software will inform you that the cartridge is empty. Your print quality may be affected, however.
