Cause: Copying a poor-quality picture, such as a newspaper photo, causes bands,
checks, or stripes to appear on your copy. These are called moiré patterns.
Solution: To reduce moiré patterns, try placing one or more clear plastic sheet
protectors directly on the glass, and then place the original print side down on top of
the sheet protectors.
Cause: Debris might be stuck on the glass or on the back of the document lid; this
causes poor copy quality and slows down processing.
