TROUBLE SHOOTING
Cause
A pressure mark is left due to the pressure of the roller because the CPF
absorbs moisture from the print surface and become soft in a high-
humidity environment.
• Moisture or oil of your skin will stick on the non-print area of the
CPF and make its coat swell and cause scattering. Fingerprints can
be seen in such a case.
• Moisture or oil of your skin attached on the print area of white ink
lowers the ink's scattering performance and the area becomes
translucent. Fingerprints can be seen in such a case.
Remedies for Print Quality Troubles
Remedy/Points to be checked
If the CPF is not used for a while, remove the roll from the
printer, wrap it in its individual bag and then store it in its
individual box.
Select [BACK POSITION] for [FRONT EDGE STAND
BY] when using transparent film. (The nipping position is
set 5 mm from the edge of paper so as not to affect the print
area.)
After panel feeding, the front edge stand by position is set
normally if a panel cut is made.
• When handling the CPF, hold it by the edges.
• Because the oil and moisture of hands affect print quality,
handle the CPF wearing cotton gloves.
• The fingerprints attached on the non-print area can
become difficult to see if wiped off with a cotton cloth
and such.
