Black Mark Layout And Operating Condition - Citizen PPU-700 User Manual

2.3.4 Black Mark Layout and Operating Condition

Black marks are selected at two places on the back and one place on the front
●
(PCS value is 0.9 or more).
* BM position is an option of factory shipment.
Though printing is available on the printing side having a black mark on the
●
back, print density may become thin depending on the type of paper; therefore,
user's notice such as printing on the place without black mark is necessary.
Distance between black mark and black mark sensor is approx. 32.5 mm. If
●
black mark is detected within this distance, next black mark is detected.
Cut position when black mark is detected by the GS+S command (black mark
●
detection command) is about 45 mm with the top of black mark used as a
reference.
Amount of automatic paper feed at the detection of black mark can be set by
●
the ESC Y n1 n2 command.
Basically cut command can be executed in any condition. If minimum distance
●
for issuing a ticket (80 mm) is not satisfied, paper feed as much as the shorted
amount is added by the printer.
* The user is requested to prepare the printing layout in consideration of the
above regulations.
