Canon MB5450 Series Online Manual page 1227

When the paper is jammed while layout printing, 2 on 1 copying, or 4 on 1 copying is in
progress, it is possible that some pages are not printed if you resume printing after clearing the
paper jam error. In this case, cancel printing and reprint from the beginning.
• If you turned off the printer while taking the appropriate action of the paper jam error:
All jobs in the print queue are canceled. Redo the printing.
Note
• When reloading the paper, make sure you are using suitable paper and loading it correctly.
Align the paper guides with the both edges of the paper when you load paper.
• If the message about paper jam is displayed on the touch screen of the printer or on the
computer screen when you resume printing after removing all the jammed paper, a piece of
paper may remain inside the printer. In this case, make sure no piece of paper remains inside
the printer.
• We recommend using paper sizes other than A5/A6 to print documents with photos or graphics.
A5/A6 paper may curl and jam as it leaves the printer.
If the measures above do not solve the problem, contact your nearest Canon service center to request a
repair.
