2.4 Special Paper
2-11
Envelopes
Envelopes must be fed manually.
Since the composition of an envelope is more complex than
that of ordinary paper, it is not always possible to ensure
consistent printing quality over the entire envelope surface.
Normally, envelopes have a diagonal grain direction. See
section
Grain on page 2-5 . This direction can easily cause
wrinkles and creases when envelopes pass through the
printer. Before purchasing envelopes, make a test print to
check whether the printer accepts the envelope.
Other handling cautions follow:
• Do not use envelopes that have an encapsulated liquid
adhesive.
• Avoid a long printing session for envelopes only.
Extended envelope printing can cause premature printer
wear.
• To avoid jams caused by curled envelopes, stack the
printed envelopes no higher than 10 on the output tray.
Colored paper
Colored paper should have the same specifications as the
white bond paper listed. In addition, the pigments in the
paper must be able to withstand the heat of fusing during the
printing process (up to 200
°
C or 392
°
F).
Pre-printed paper
Pre-printed paper should basically be bond paper. The inks
on the paper must be able to withstand the heat of fusing
during the printing process and must not be adversely
affected by silicon oil. Do not use paper with any kind of
coating, such as calendar stock.
Recycled paper
Select recycled paper that has the same specifications as
white bond paper. See
Table 2-1 on page 2-2 . Recycled
paper, however, does not have to be as white as white bond
paper.
Note
Before purchasing recycled paper, make a test
using the printer and check whether the print
quality is satisfactory.
