Canon's High Resolution Paper - Canon MP-C635 User Manual

Do not leave any type of film in the sheet feeder for long periods of
time. Dust and dirt may accumulate on the film resulting in spotty
printing.
To avoid smudging caused by fingerprints, use a pair of thin cloth
gloves while loading and handling the film.
To avoid fading, do not expose the printed film to prolonged
sunlight.
Store unused papers and films flat. Do not remove papers from their
protective packaging until you are ready to use them.
Store unused film at temperatures between 59°F to 86°F (15°C to
30°C). The relative humidity should be between 10% and 70%.

Canon's High Resolution Paper

When printing on High Resolution Paper, you need to lift the paper
output guides on both sides of the output tray. These guides help
support the document as it exits the MultiPASS. The guides keep the
sheet from sagging as it exits the unit, which can lead to poor print
quality.
Using the Paper Output Guides
Lift both paper output guides until they are vertical. Always lift both
output guides.
