2. Printing Defects and Countermeasures

The printing result has hori-
zontal lines (pulling wrin-
kles).
1) When large areas have
been printed with high
density.
2) When the back tension
is strong.
1) When large areas are to be printed, set "Default LUT" of
maintenance in the service mode to "Standrd" or "Low".
2) Check for smooth turning of the spring of the ink cas-
sette. Disassembly and clean if the spring does not turn
smoothly.
3) Check for smooth turning of the bobbin on the supply side.
Exchange the cassette if the bobbin is not turning
smoothly.
4) Check for a heavy load of mechanism, motor, etc. on the
ink supply side.

No transfer to the left or the
right side of the card.
1) Retransfer position is
wrong.
2) Card stop position is
wrong.
1) Confirm if the operation of the card edge sensor and the
film sensor is normal, and if these sensors are firmly se-
cured.
2) When sensors are replaced, setting “Offset Trf X” for the
film sensor and/or setting “Offset Card X” for the card edge
sensor shall be adjusted.
Large card bend

(in case of double-sided printing)
Heat deformation occurs
easily especially with PVC
cards.
1) The environmental temperature to use is adjusted to the
temperature range of specification. If this is still not suffi-
cient, additionally lower the temperature setting for the
retransfer roller to reduce deformation by heat.
2) Adjust the temperature setting and the cooling time set-
ting for the bend remedial roller.
3) When double-sided printing is done with the temperature
setting for the bend remedial roller set to a high value, the
cards will become deformed.
When the card is deformed with a convex face and a
concave reverse-side, make the reverse retransfer speed
higher or change the setting of the bend remedy mode.
