Canon BJC-250 - Manual (Page 28)

Paper Guidelines
When selecting or loading paper, please remember the following:
Attempting to print on damp, curled, wrinkled, or torn paper can cause paper jams
and poor print quality.
Use cut-sheet paper only. You can use multipart paper.
When using graph paper, the lines may not match because the 1/6 inch line spacing
of the printer is slightly less than that of graph paper.
If the print density of your page is very high , light paper stock may curl slightly due
to the large amount if ink. If you need to print dense graphics, try printing on
heavier stock.
Do not use thicker paper than meets the specifications for this printer. Printing with
a paper that is thick enough to come in contact with the print head nozzles may
damage the BJ Cartridge.
