        Cle arin g J a m sClearing Jams
When ,  or  appears on 
the display, remove jammed paper from the machine first, then from the paper cassette or 
multi-purpose tray if necessary. Check the following if you experience repeated paper jams:
Fan and tap the paper stack on a flat surface before loading it in the machine.
Check that the paper you are using meets the requirements for use. (See “Paper 
Requirements,” on p. 2-6.)
Make sure you have removed any scraps of paper from the inside of the machine.
When removing jammed documents or paper, take care not to cut your hands on the edges of the document or paper.
When removing jammed paper or when inspecting the inside of the machine, do not allow necklaces, bracelets, or other 
metal objects to touch the inside of the machine, as this may result in burns or electrical shock.
If you tear the paper, remove any torn pieces to avoid further jams.
If loose toner comes into contact with your skin or clothing, wash with cold water. Warm water will set the toner.
Do not force a jammed document or paper out of the machine. Contact Canon Customer Care Center if needed.
