Tips on using transparencies
From the printer control panel, set the paper size, type, texture, and weight in the Paper menu to match the
transparencies loaded in the tray.
Print a test page on the transparencies being considered for use before buying large quantities.
Use transparencies designed
specifically
for laser printers.
Avoid getting fingerprints on the transparencies to prevent print quality problems.
Before loading transparencies, flex and fan the sheets to prevent them from sticking together.
When printing on large volumes of transparencies, make sure to print by batches of only up to 20 with an
interval of at least three minutes between batches, to prevent the transparencies from sticking together in
the bin. You can also remove transparencies from the bin by batches of 20.
Paper guidelines
Paper characteristics
The following paper characteristics aect print quality and reliability. Consider these factors before printing on
them:
Weight
The printer trays and multipurpose feeder can automatically feed paper weights between 60–176 g/m
2
(16–
47lb) grain long paper. The 2100sheet tray can automatically feed paper weights up to 60–135 g/m
2
(16–36lb)
grain long paper. Paper lighter than 60 g/m
2
(16 lb) might not be
sti
enough to feed properly, and may cause
jams.
Note: Twosided printing is supported for 60–176 g/m
2
(16–47lb) paper.
Curl
Curl is the tendency for paper to curl at its edges. Excessive curl can cause paper feeding problems. Curl can
occur after the paper passes through the printer, where it is exposed to high temperatures. Storing paper
unwrapped in hot, humid, cold, or dry conditions, even in the trays, can contribute to paper curling prior to
printing and can cause feeding problems.
Smoothness
Paper smoothness directly aects print quality. If paper is too rough, toner cannot fuse to it properly. If paper
is too smooth, it can cause paper feeding or print quality issues. Always use paper between 100 and 300
Sheeld points; smoothness between 150 and 250 Sheeld points produces the best print quality.
Moisture content
The amount of moisture in paper aects both print quality and the ability of the printer to feed the paper correctly.
Leave paper in its original wrapper until it is time to use it. This limits the exposure of paper to moisture changes
that can degrade its performance.
Store paper in its original wrapper in the same environment as the printer for 24 to 48 hours before printing.
Extend the time several days if the storage or transportation environment is very dierent from the printer
environment. Thick paper may also require a longer conditioning period.
