Canon imageFORMULA P-208II User Manual page 25

A document must meet the following criteria to be scannable:
●
When scanning multiple documents of different sizes, place
the documents so that they cover the entire span of the feed
rollers.
●
Scanning documents before the ink is dry can cause problems
with the scanner. Always make sure that the ink on a document
is dry before scanning it.
●
Scanning documents that are written in pencil or similar
material may make the rollers and scanning glass dirty, which
can lead to smudges on the scanned image and transfer the
dirt to subsequent documents. Always clean the internal parts
of the scanner after scanning such documents.
●
When scanning a two-sided document that is printed on thin
paper, the image on the opposite side of each page may show
through. In this case, adjust the scanning intensity in the
application software before scanning the document.
●
It is recommended that thin documents are fed one sheet at a
time.
Scanning the following types of documents can cause a paper jam or
malfunction. To scan such a document, make a photocopy of the
document and then scan the photocopy.
