C912 horizontal lines in print

try to replace magenta , Yellow , CYAN

clean the print heads and align them

Hello,
you have to replace toner cartridges (unfortunately).
Same problems can be occured whit CP 1025 too
the problem is - cartridge image drum failed
Good luck!

Either the ink you are using is not going to give the color you want, or you have print heads that are blocked.

the problem is not with the printer but it is with the ink that might be damaged, this is located inside the printer

try to clean the noozle of you catridge..... then try again...... or try to shake it

Most probably you have to do the Color Registration Settings and the Color Calibration.
The Color Registration will fix the fuzzy printing and the Color Calibration the way how the colors looks. The Color Calibration it is done automatically after each batch of 40 or 80 pages and if you need you can do a manual Color Calibration BUT THE COLOR REGISTRATION must be done manually.

Go to Menu->Others->Service->Color Registration and print a test chart. Will print a page and you have to read the alignment of some lines Cyan Magenta Yellow Black with some numbers. Check the Advanced user guide for details. Basically you have to read the number / letters of each color where 2 lines are matching. Then you can enter those numbers into the printer for each color.

If the Cyan only is off then will be easy ...

Without knowing what printer you have or what things you have tried I can only guess here. It sounds like you need a new cartridge. A color ink cartridge will have 3 colors of ink for most printers...cyan (blue), magenta (purplish-maroon), and yellow. Depending on what you print it is very possible that you could run out of one of the inks before the others. Printing green can be an indication that you are out of magenta ink. The cyan and yellow inks will combine and look green.

You can remove the cartridge and run a tissue over the printhead and see if you see all 3 colors as a quick test. If you only see cyan and yellow, then the magenta is probably empty or dried up. If you see all 3 colors I would reinsert the cartridge and try printing again. It is possible that the magenta was just clogged and you cleaned it with the tissue. If it still doesn't print all colors your best bet is probably to just get a new ink 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.
