Kevbo37 Posted November 30, 2010 Report Share Posted November 30, 2010 It is difficult to tell but it looks as though it might be a crease or a fold in the paper. Is this line smooth to the touch or can you feel a ridge? If it is smooth and not a crease then the fineness and sharpness of the line indictes it is a blockage near the paper. The jagged nature of the line indicates it is something moving around as the print is being exposed. I have seen similar problems when a hair or fiber of some sort is trapped in the exposure section and is being moved by air currents as the print is being exposed.

ghn5ue Posted November 30, 2010 Report Share Posted November 30, 2010 Remove the laser unit and look carefully around the area where the paper passes under the laser. I had this problem once, turned out to be a small clear thread in the exposure area, had to use a flashlight to see it! Quote Link to comment Share on other sites More sharing options...
Christina Rose Posted December 1, 2010 Report Share Posted December 1, 2010 it could be a moving dust stick on the rollers ( Exposure) . take out laser unit and check the rollers. especially rotate the roller and check entire area. you must need a table to see from the top. cheers.

Christina Rose Posted December 1, 2010 Report Share Posted December 1, 2010 may be a hair or tiny part of a twain could stick on rollers. so it wont come all the prints. Quote Link to comment Share on other sites More sharing options...
