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 fs 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.
