My lexmark C540n is printing with large yellow lines. Can you please advise?

SOURCE: LEXMARK PRINTER X84-X85 MODEL4403 K11

Try to clean the cartridges/nozzle using the utility of the printer installed on your computer..

Hope that helps..........

SOURCE: Will not recognize new yellow ink cartridge

I junked it!

SOURCE: black ink cartridge is leaking and black line is running down back of page

YOU CAN TRY PULLING THE CARTRIDGE OUT AND WITH A CLEAN , VERY SOFT CLOTH , CLEAN THE HEAD GENTLY ....SOME CARTRIDGES ARE JUST FAULTY ....HAVE YOU TRIED RETURNING IT OR GOING TO CANON SITE AND TROUBLESHOOTING ?

SOURCE: The cartridsge printe red and blue fine. No yellow

The print head for the yellow color may be clogged. Check the manual to see how to turn on your print head's cleaning system. Run it until the yellow starts to print properly. If after running the cycle 4 or 5 times you still can't get any yellow to print you will probably have to take the printer to your local repair depot to have them diagnose the problem.

Try this :

Take out the power cable from the back of the printer keep on tapping the power button for 30 secs ; then plug it back.
Take out the catridges clean them with a Lint free cloth (copper contacts); also clean the catridge slot of the printer; put in back the catridges ;
Unplug the power cable from the back of the printer; press and hol down the (#) and the (6) button simultaneously with one hand and with the other hand put in back the power cable; and then release the (#) and (6) button;
It will perform a reset on the printer
IF still then it doesn't work then the catridge slot's copper contacts has gone bad and need to replace
