Notes on slip paper
Slip paper should be flat, without curls, wrinkles, or camber,
especially at the paper edges. Otherwise, the paper may
become ink stained.
When using multiply-ply carbon copy paper, it should be flat
and the glue area should be as small as possible.
Glue area should be located at the top or left edge of the slip
paper.
Since TOF and BOF sensors are optical sensors, paper having
holes at the sensor positions or translucent paper should not be
used normallly. When using these papers, be sure to disable the
paper sensors by ESC c 4.
When using slip paper of 80 mm (3.15") long or less, load the
paper so that it is fed straight.
Use thinner paper (N30 or equivalent) between the top and
bottom sheets of multi-ply paper. If thick paper is used, the
copy capability is lowered.
4-4 Reference Information
Copying capability is influenced by
the ambient temperature. Printing
must be performed under the
conditions, described in a Table
below:
Ambient temperature (print mode)
