When you load the envelopes, arrange the stack of envelopes on a firm, clean surface first, then press down firmly on the edges to make the folds crisp.
Adjust the slide guides to the width of the paper stack.
Make sure that the paper stack does not exceed the paper limit guide.
Some types of paper may not feed properly into the multi-purpose tray. For high quality copies, be sure to use the paper and transparencies recommended by Canon.
When making copies of a small document or thick paper, etc., the copy speed may be slightly slower than usual.
