Tip & How-To about Office Equipment & Supplies
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".
