Rollers are leaving black smudges on my checks

How do I clean the rollers?  They are leaving black smudges on my checks.

    The roller is discolored on the right side, but looks fine on the left side.  The smudges are mostly on the left side, with a few faint ones on the right side.

    The roller is green, and on the right side is a wavy lighter/bluish color, but I think both sides are outside the borders of the paper.  Could the black smudges be coming from somewhere else?

Are you positive that this is a 'roller' problem.  Black smudges usually indicate a drum problem (your toner cartridge).  If you pull it out, you'll see a flap that should move back and forth.  If you move that flap, you'll see a shiny cylendar.  That's the drum.  See if you can see any marks on it (don't touch it with your hands.) 

The problem is, it's hard to tell whether or not it's the drum just by looking.  Your best bet is to see if replacing the cartridge takes care of the problem.

A laser printer has its rollers (which I believe you said you cleaned...very important) and the cartridge you put in the printer has rollers too! Carefully check them and the wiper on the cartridge. If all of those things are clean, then you should get clean copy!

I got smudges when i print ,how can i clean this

It looks like you've managed to get some ink on the rollers. 3 Possible solutions:-

1) Check your printer maintenance menu, there may be a roller cleaning option.

2) Print a document which has printable data on almost all lines, but with empty cartridges. You'd be using a piece of paper more or less as a mop.

3) Final alternative, it getting right into your printer and cleaning it by hand. Printer ink is water soluble so damp cloths/cotton buds should be man enough for the job. The parts you need to concentrate on are the rollers and the small sponge wells underneath where the print cartridges rest.

Black vertical lines in copies

You need to clean the glass. Open up the feeder and you have a large piece of glass for scanning and to the left a smaller piece of glass that it uses to scan from the feeder. Clean this smaller piece of glass; even the slightest smudge can leave a black streak.

Cannon Pixma MP500- I get a solid black line on the reverse side of a printed page. Went through all the cleaning procedures and new cartridge, no change.

For some reason, the printer is designed to dump ink into the bottom of the tray before feeding on the paper. The paper is then dragged over the ink, leaving the black line. This is a software issue, not a hardware one. I'd advise that you update all of your print drivers, as well as your firmware.

A temporary fix is to clean the rollers and base plate of the printer for ink spills.

Check for any bits of paper or debris that may be caught in the printer. Be careful to feed in the paper perfectly straight, as this printer does not have good rollers, and it will cause paper to break off and cause problems. If any debris has caught or absorbed ink, it will cause the back of the paper to smudge, and you have black lines.
