Before we send out a service tech lets check a few things:

1. Does the line appear when you lay the page to be copied on the  platen (flat glass)?

a.  Yes – Then I suggest that you take a soft cloth and carefully clean the glass. You can use glass cleaner.

b.  No – Simple things such as dust particles or white out can cause the line. Since it does happen when you copy on the platen then we must look further

2.  Does the line only appear when you run the page to copy through the automatic document feeder?

a.  Yes – Then you need to look to the left of the platen and clean the thin strip of glass.  We have produced a video on precisely this problem, please look in our video section.

b.  No – Then you have an internal problem and will probably need a service technician to go over your machine.
