Not printing Hi I am working on a Lexmark C510 printer. ITs not printing black and yellow. Its prints blue and red bars on the paper thats all, with the self test. I changed the engine borad, io board, formatter board, scanner, clutches, still not change. What could the problem be? Its like its not transfer the toner on the photodev cart.

YOU CAN GO TO THE PRINTER PRINT PREFERENCES AND CHECK THE BOX FOR GREYSCALE ONLY.

For 34 Short Paper error, reseat the tray guides and make sure it is set properly. Also, set the correct settings in the computer. For blank pages, always double-check the paper settings and again the settings in the computer. For not printing black, print the Print Quality page and see what color is not printed or not showing. If Print Quality shows black, try printing any document from any application in the computer. Check if you still have the problem. If problem is not resolved, leave a comment so I can get back to this.

Try the old one again. If this works you have a defective new catridge. This sometimes happens.

it is the problem your copier drum unite

your copier scaner mirror is dust over clean it then solve it

replace all ink cartridges.

The Z715 needs a #50 black ink cartridge and a working color cartridge to print. To check if there ios ink coming out of your black or color cartridge touch the bottom of it to a paper towel and if you see a solid black blob or 3 blobs of Yellow, blue and red for the color then your problem is else where. If U are printing stuff from the internet sometimes the printer will try to use the color cartridge to print this so even though the black is working it comes out blank if the color is dry

Seriously, buy a new printer. Companies sell toner, not printers! The printer is basically a "freebie" and is a marketing vehicle to sell toner. I tossed my C510 into the dumpster. It had four new toner cartridges. System diagnostics said that everything was at 95% or better. The printer had about 1600 prints on it. The first set of toner cartridges (full at purchase!) printed great. Then, I got dotted lines on clean prints. Or, I would get washed out, yellow tinted print and often, there was no black print. I called a printer repair shop and they laughed and told me to chuck the printer - they were suprised it lasted through the first set of cartridges. Lexmark literally "ignored me to death."

I will NEVER buy another Lexmark. The Brother and HP color lazers are probably the best bet. I have two HP B&W's that are paper pumps - an old 4V and a 6MP. The sad part is that I paid a bit more for the Lexmark than the competing HP. You live and then you learn!

goto menu "1" -- find black and white lock and set to off. I almost threw out a printer that was given to me because of a menu setting.

Thank you Krissy! I had the same problem with the horrible grinding noise.

I took out all of the toners and the photo developer and noticed that my Blue toner was leaking all over. After reading your post, I tried replacing the toner. It worked!!! No more noise - and no more mess!
