Shifting of Printing and Cutting Position within +/-0.5mm
or within +/-0.3% of distance traveled is in tolerance.
Media will expand or shrink depending on the
temperature and humidity. Therefore, if the elasticity
differs when printing and when cutting, Printing and
Cutting Positions will be shifted. By accustoming the
media to the environment before printing, it could make
the difference of elasticity minimum.
Carry out [ENV. MATCH] in User's menu. Cutting
position in the carriage moving direction is detected by
the Motor ENCODER while the printing position is
detected by the ENCODER SCALE. The ENCODER
SCALE expands and contracts depending on the
environment (temperature & humidity), and it causes the
Print/Cut shifting problem in the carriage moving
direction. (The shifting amount becomes bigger as it is
far from the carriage standby position.) This function
adjusts the machine to optimize its state to the
environment where it is used. This function is the same
adjustment as [LINEAR CALIB.] in Service menu.
When you are performing printing and cutting, use a
value of "0" the menu of [CALIBRATION] -- [CUTTING
ADJ.]. This setting is using the machine for cutting only.
Print / Cut Position Adjustment is to calibrate the error in
the relative positions of Head and Tool Carriage due to
the manufacturing tolerance and correct an error in
Position
printing and cutting positions. Therefore, if this
adjustment is not performed correctly, printing and
cutting positions will be shifted.
Media Feeding amount is slightly different in each media
because of the difference in its thickness. When the
feeding amount changes, landing position of the dots will
be changed and results in banding.
Print / Cut Offset Adjustment can not be done correctly
when the Crop Mark Sensor is dirty. When Crop Mark
Sensor is dirty, relative positions of Printing and Cutting
can not be corrected and cause printing and cutting
positions to be shifted.
When the sensitivity of Crop Mark Sensor is low, relative
Sensor positions of Printing and Cutting can not be corrected
and cause printing and cutting positions to be shifted.
Tool / Crop Mark Sensor Position Adjustment is to
calibrate the error in the relative positions of Tool and
Crop Mark Sensor. Therefore, printing and cutting
positions will be shifted when the relative position of Tool
and Crop Mark Sensor is shifted from the correct
Position
position. And also, the Print / Cut Offset Adjustment is
supposed to be done based on this adjustment.
Therefore, the printing and cutting position will shift even
if not Crop Marks are not used.
