Troubleshooting for abnormal colors of ClearProof Film (CPF)
Symptom Occurrence condition
Scratches or traces occur and
ink is transferred to the part in
contact with the media
because the print surface is
touched immediately after
printing.
Scratches, ink transfer when
piled
When printing using the
basket for Epson Special Film,
roll paper (CPF) with a strong
curl curls up when stacked,
and scratches are caused
because the printed side
touches the paper eject
section.
TROUBLE SHOOTING
Cause
Scratches or traces may easily occur and ink may be transferred to the
part in contact with the media because ink on the print surface is not
dry immediately after printing. Especially at the end of the printed side,
ink is very easily transferred because the printed side is wet, for ink
there has just been printed.
The basket for Epson Special Film is designed so that the CPF can
stack it without curling up; however, when printing on media from
other suppliers with a strong curl, scratches may be caused because the
media curls up.

Remedies for Print Quality Troubles
Remedy/Points to be checked
• Always use the basket for Epson Special Film when
printing on CPF. (If the basket for normal paper is used,
scratches are caused when the print surface touches the
basket cloth.)

• Remove the printed sheet every time it is printed and
make sure not to let them stack up.
• The guaranteed media length that can be stacked on the
basket for Epson Special Film is from 420 to 914.4 mm.
• In the case of roll paper with a strong curl, do not use the
basket, but print in the setting [Roll Auto Cut Off], and
carry out [Manual cut]. See "Cutting of Roll Paper" on
page -43.
• The CPF's curl is reduced by the adoption of roll cores
with wide diameter. The maximum curl value guideline is
an average of 36 mm in height (at the 6 points given
below) for a 15 cm cut length placed with the concave
side up.
