Re: Rollers are leaving black smudges on my checks

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.

    1. Unplug the power cord from the printer, and then allow the printer to cool.
      Figure 1: Power cord location
    2. Open the door and remove the print cartridge.
      Figure 2: Opening the door and removing the print cartridge
    3. Locate the pickup roller inside the printer. It is the large gray roller in the center, behind where the print cartridge was before it was removed.
      Figure 3: Locating the pickup roller
        WARNING: Avoid touching the transfer roller while removing and replacing the pickup roller. The transfer roller is the black, sponge rubber roller that is under the print cartridge area. A sheet of paper may be used to cover the transfer roller while removing or replacing the pickup roller.

    4. Rotate the bottom of the pickup roller towards the front of the printer.
      Figure 4: Rotating the bottom of the pickup roller
    5. Gently pull the pickup roller straight out.
      Figure 5: Pulling the pickup roller straight out
    6. Dab a lint-free cloth in isopropyl alcohol, and then scrub the roller.
      Figure 6: Dampening a lint-free cloth with isopropyl alcohol
        WARNING: Alcohol is flammable. Keep the alcohol and cloth away from open flame. Allow alcohol to dry completely before closing the printer and plugging in the power cord.

    7. Using a dry, lint-free cloth, wipe the pickup roller to remove loosened dirt.
      Figure 7: Wiping the roller to remove dirt and debris
    8. Allow the pickup roller to completely dry before reinstalling it in the printer.
      Figure 8: Allowing the roller to dry completely before reinstalling
    9. Position the top of the pickup roller in the slots.
        NOTE: The top of the pickup roller has round tabs. The bottom of the pickup roller has rectangular tabs. The flat side of the pickup roller goes to the back of the printer.

      Figure 9: Positioning the roller in the slots
    10. Rotate the bottom of the pickup roller towards the back of the printer. The roller will “snap” into place when properly seated.
      Figure 10: Rotating the bottom of the new pickup roller
    11. Reinstall the print cartridge and close the printer door.

    12. Reconnect the power cord of the printer in to turn the printer back on.

Black spots on each page

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!

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.

Smudges on items printed

Take the cartridge out and shake it, when you do this thought make sure you cover where the toner goes out of or you'll make a mess! I had this same issue with my laser printer and this resolved it.

If that doesn't fixya then you may want to clean the rollers you can buy sheets to run in them.
