Symptom Occurrence condition
Sticking and ink transfer • When the printed CPF is
during storing stored in a pile, the print
sides stick to the others.
• When the printed CPF is
stored in a pile, ink is
transferred and the print
side is scratched.
TROUBLE SHOOTING
Cause
• Because the ink is undried and soft soon after printing on the CPF,
scratches or ink transfer occurs if the prints are piled immediately.
• Even if dried after printing, the coat layer absorbs moisture and
becomes soft if the medium is stored in high humidity. In such a
case, printed areas stick if they are left in a pile.
• Especially in the Surface Print mode, scratches easily become
conspicuous on the area where color ink is printed on white ink.

Remedies for Print Quality Troubles
Remedy/Points to be checked
• After printing, take the film out from the basket for Epson
Special Film and place it with the printed side up on a flat
place such as a desktop to dry it well. The average drying
time is approximately 30 minutes.
• Do not touch the print surface during printing or drying.
Otherwise, ink may come off, or scratches, discoloration
or uneven color may occur.
• Dry the prints completely before peeling the Release
Film. (Be careful not to fold or bend the print surface
when peeling the Release Film.)
• When storing the prints in a pile, put sheets with water
absorbability (such as plain paper) between the prints. If
paper with no water absorbability such as the backside of
the CPF or the Release Film is piled, it may stick to the
Coated paper
print surface.
• To protect the prints from scratches, avoid holding the
printed area even with the paper for protection.
• When storing printed media, make sure to keep the usage
environment (See P.152)
