Did you know you should clean your ‘slit glass’? Many people do not realize this part of the copier (see the picture below). Nor do they consider cleaning it. Believe it or not this is the most common cause for lines on copies. The example below is an example of what dirt on the slit glass can do to your copies. With a simple swipe from a cleaning cloth your copies will no longer have lines.
If you are unsure if your copies have lines on them due to the slit glass, you can simply place your original document on the big pane glass and make a copy without using the document feeder. This simple test will help you determine where the problem is.
Things like gel pens, sticky notes and whiteout are the most common things that cause the slit glass to get dirty. Some gel pens are not quick drying and leave ink on the glass. If you let the gel dry on your paper it shouldn’t be a big issue. Some gel pens come in a quick dry (for left handed people) and you may want to consider these if you notice an issue. Sticky notes and sticky tags should be removed before going through the document feeder. Sticky notes once removed leave behind some of the glue and this causes the slit glass to become dirty. The same idea applies to the whiteout. While I know there are many different types of whiteout (pens, tape, and paint on) they can also cause dirt on the slit glass.
