Thick Paper
Before loading thick paper in the MP tray, fan it and align the edges.
Some thick paper may still have rough edges caused by a paper cutter
on the back side. Remove any such rough edges just as with Postcards
by placing the paper on a flat surface and rubbing the edges gently a few
times with a ruler. Copying onto paper with rough edges may cause
jams.
Note If the paper is not supplied correctly even after it is
smoothed, load the paper in the MP tray with the leading edge
raised a few millimeters as shown in the figure.
Colored Paper
Colored paper must conform to the specifications listed on the page 6-2.
In addition, the pigments in the paper must be able to withstand the heat
of copying (up to 200 °C or 392 °F).
Preprinted Paper
Preprinted paper must conform to the specifications listed on the page 6-
2. The colored ink must be able to withstand the heat of copying. It must
be resistant to silicone oil as well. Do not use paper with a treated
surface such as glossy paper used for calendars.
Recycled Paper
Recycled paper must conform to the specifications listed on the page 6-
2; however, its whiteness may be considered separately.
Note Before purchasing recycled paper in volume, try testing a
sample to ensure that the copy quality is satisfactory.
