7.5 Wiping Position Adjustment
Wiping position adjustment consists of two operations: wiping unit adjustment and single color
adjustment.
During wiping unit adjustment, you will align the carriage standard position and the wiper unit
position. Then you will enter an adjustment value to adjust the wiping position for all print heads.
During single color adjustment, the wiping position of only the selected print head is checked and
adjusted. To adjust the wiping position, always perform the wiping unit adjustment before the
single color adjustment. The wiping position may shift if the adjustment order is reversed.
Note
Wiping position adjustment is required after the following operation.
(1) Wiping unit replacement or printer relocation
Perform the wiping unit adjustment only.
(2) Print head inclination adjustment
Perform the wiping unit adjustment and the single color adjustment.
* If these adjustments are not performed, the wiping operation will not be executed properly
which may cause print defects.
