Print Quality Problems - Canon MultiPASS C755 User Manual

The MultiPASS suspends printing after each line.
The BJ cartridge print head may have become too hot. If this happens, the
MultiPASS may be slowing its printing speed at the end of each line to protect
the BJ cartridge print head.
• Stop your print operation and wait several minutes to allow the MultiPASS to cool.
Then start your operation again.
Print jobs vanish or you are printing garbage.
For the following, 1 MultiPASS Suite User's Guide :
– Another Windows
printer port the MultiPASS Server is using. This conflict can result in strange
printing behaviour.
– The MultiPASS Service (MPService) may not be loaded properly.
The printout curls.
Your page may include a large amount of ink.
• Leave the page in the output tray for 30 to 60 seconds to allow the ink to dry. Then
remove the page being careful not to touch the document tray (if it is open). Allow the
page to dry further, then roll it in the opposite direction of the curl. (Should you dirty
the document tray when removing the page, wipe it clean with a clean, soft, lint-free
cloth moistened with water or diluted dishwashing detergent solution.)
• The paper you are using may be too thin. Printing dense graphics on light paper stock
may cause the paper to curl. Try using heavier stock.
Your PC indicates a device time-out.
A device time-out occurs when the PC sends data to the MultiPASS, but the unit
does not respond. The MultiPASS may be unplugged, not connected to the PC, or
have a paper jam.
• Make sure the MultiPASS is plugged in (1 p. 2-8), and that the printer cable is
securely connected to the unit and PC (1 p. 2-7). Clear any paper jams (1 p. 13-4),
and make sure paper is loaded properly in the multi-purpose tray. (1 p. 2-17)

Print Quality Problems

The print quality is not what you expect; print is not clear, is
splashed, has missing dots or white streaks.
The print media you are using may not be supported by the MultiPASS.
• Make sure you are using the recommended print media. (1 p. 5-2)
You may be printing on the wrong side of the paper.
• Some papers have a "right" side for printing. If the print quality is not as clear as you
would like it to be, try turning the paper over and printing on the other side.
