OK Thanks for the tip. However, discovered and fixed the problem. While refitting glass, discovered wobble, arising from twisted chassis, arising from sagging corner of countertop on which the machine was standing. Once the machine was placed on level surface and corner propped to over-compensate, copies were fixed.

2-the scanner adjust the scanner - turn off machine remove glass and adjust
3-if making from feeder the glass itself may be too dry, spray WD40 and wipe leaving a smooth surface.

Black lines across copy when using Document Feeder.

Many people ask this same question over and over again. "I get black thin line (s) when using document feeder. If my original is on the platen glass copy is OK."

Well, in most copiers, be it Xerox or Canon or Sharp there is same principle in use. When document is moving it is exposured (copied) by a steady non-moving exposure lamp. If there is any dirt or even a dust particle on the narrow platen glass it will print out as a line.

Most people don't understand this principle and they say "I 've cleaned the platen glass".OK, they have cleaned the BIG glass, but the glass is the narrow one next to the big one. Very often there is glue or white correction lacquer on the platen which of course adheres more dirt.

You may use even the strongest solvents to get dirt off the glass. Remember, it is made of glass and won't get hurt even if you use thinner or nail polish remover.

This tip applies also on fax machines. The receiving end may call back and say "your fax has a lot of lines across the copy".

How do I get rid of the lines when I make copies. It dose not happen if I print a scan

If you are using the ADF ( automatic document feed ) for your copies, raise the scanner cover and clean the strip window to the left of the main platen. If you are using the platen for copies and getting lines where scans are clean - you have a physical issue and it should be checked out by a technician.

Photocopier producing skewed finished copies. What can be the problem?

If the image is skewed on your paper, you have a registration bushing broken.

If the image is OK on the paper, look for a piece of paper or a little thing in the way of copy

When I fax it copies a black line is on the page. And when I copy from the top part it copies a black line. How can I fix that?

are you getting black lined copies while you are trying to send a fax or black lined images are obtained at the receiving end. Is there any problems while copying from platen glass. if it's ok, then check if there is any thing on the stream reading glass (the small sized glass plate meant for ADF) & clean it.

The screen says the Paten glass needs to be cleaned. What is the paten glass? Also when copies are made a black line is showing up on the edge of the copy.

platen glass means that you need to clean the copy glass - glass where you put the originals for copying.
If you have an auto document cleaner there is also small glass on left side of "platen glass" wich is seen when you open the copy machine cover or dadf.

The black line is probably from dirt on copy glass, I pressume because courectour liquid ( most common ). use some stronger detergent or wd-40 to disolve the dirt and clean with glass detergent and dry it.

If you still have the black line try to print something from machine.If you do not have it on print its the copy glass problem - clean it - again.
