Scanning duplex I get a line down the righthand side of all alternate pages?


With very limited information, I suspect if you observe closely on the side that has the line printing you will find a dark smudge on the glass. If this is found you should be able to use a little rubbing alcohol on a clean cloth an remove the smudge.

Smudge line on side of page


Smudges are most likely from the toner cartridge. If you can take your finger and run over the print and it smudges, then it is the fuser.

4 - black ink smudges (1/32" wide x 1/16" high) in right margin


Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps

Printer is creating a crease and smudge down center of page.


There sounds like there is somthing in the path of the printhead. Using a flash light, remove back cover of machine and look for a small piece of paper,etc. Be careful not to jam anything in to th machine. It may take running a thick piece of paper through manually with your hands to remove the object.

Smudge on left side of paper


It seems like your PCU's are dirty and are picking up extra toner. Take them out and look at the green rollers, any extra finger prints or dirt on them? Clean them with a clean paper towel.

Also, check your transfer unit below the PCU's, that may need cleaning or replacing. You can pull that out after removing both PCUs, turn the little screww and look at it. That can also be cleaned with a cleaning wipe or a damp paper towel. There's a little tab that you can turn to free the rollers (they'll still be a little tight) bu then you can turn the rollers to expose more surface area.

Good luck. Be sure to rate the post if it works for you.

Smudges down left side of paper


Maybe something attached (corrector fluid or adhesive)on drum (green cylinder - don't touch it!) or more probably the fixing film on the fusing unit is damaged (probably some paper clip left over input bin, or trying to remove a paper jam with some sharp-pointed thing) If you have some other printer like this around, try with another print cartridge, if error persist , the fuser film is damaged...
