Paper roll and validation paper:
Notes on validation paper
❏
For correct validation printing, be sure that a paper roll is
loaded before you use validation paper. Also be aware that the
printing on validation paper may also be visible on the roll
paper if the roll paper is pressure-sensitive paper.
❏
Use validation paper that is flat, without curls, folds, warps, or
wrinkles, especially at the paper edge. Otherwise, the paper
may become ink stained or the ribbon may get caught in the
printer mechanism.
❏
Choose validation paper carefully when glue is on the edge,
since paper feeding and insertion are affected by gluing
conditions (e.g., glue quality, method, and length) and glue
location.
❏
Using a multi-ply copy paper with a thick middle sheet may
decrease copying capability.
❏
Printing noise may change depending on paper thickness.
Noise may increase when thick single-ply paper is used.
Copy capability
Paper roll and
validation
paper: Copy capability is greatly influenced
by the ambient temperature, so
printing must be performed under the
conditions described in the table
below.
Number of copies Ambient temperature
Or 2 copies 10° to 40°C (50° to 104°F)
Or 1 copy 5° to 50°C (41° to 122°F)
