Handling Paper
3-10
Postcards
Fan the stack of postcards and align the edges before loading them in the
MP tray. Make sure the postcards you are going to set are not curled.
Feeding curled postcards may cause paper jams.
Some postcards have rough edges on the back (those are created when
the paper is cut). In this case, put the postcards on a flat place and rub
the edges with, for example, a ruler to smooth them.
Envelopes
Envelopes should always be fed from the MP tray, with the print-side up.
Envelopes must be fed from the MP tray or optional paper feeder PF-530.
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. Refer to Paper
Grain on page 3-6. 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.
• 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.
• If jams occur, try setting a lesser number of envelopes on the MP tray.
• To avoid jams caused by curled envelopes, stack no more than 10
printed envelopes on the top tray.
