Other Paper Properties
Stiffness: Paper that is too limp or too stiff may fold or bend inside the printer,
resulting in a paper jam.
Curl: Most paper has a natural tendency to curl in one direction or the other if it is
stored unwrapped. Paper will curl slightly upward when it passes through the fuser
unit. Load the paper with its natural curl downward so that it will come out flat.
Some paper also has a front and back surface. If this is indicated on the paper's
packaging, be sure to load the paper into the cassette face down.
Note
If curl is large, load the paper into the cassette in such a manner
that the paper's back surface is facing down.
Electrostatic properties: During the printing process, the paper is electrostati-
cally charged to attract the toner. The paper must be able to release this charge so
that printed sheets do not cling together in the output tray.
Quality control: Uneven sheet size, corners that are not square, ragged edges,
welded (uncut) sheets, and crushed edges and corners can cause the printer to
malfunction in various ways. Pay particular attention to these considerations if you
are choosing paper yourself.
Packaging: Select paper that is wrapped by the ream and then placed in a box.
The best wrapping is one whose inner surface is coated to protect against humidity.
Specially treated paper: We recommend that you avoid using paper listed
below which has been specially treated, even if it meets basic specifications. If you
wish to use such paper, test a sample on the printer and check that the printing
quality is satisfactory before purchasing.
• Paper with a glossy finish
• Paper with sections cut out
• Paper which is embossed
• Paper with feed holes in it
• Paper with punch holes in it
