When the black mark photo-sensor is enabled, the behaviour of the printer will change in the
following way:
–
When pressing the paper feed button the printer will feed paper to the next cutting line
according to the ticket length parameter set with the
GS ( G
command (See
SECTION –
CONTROL COMMANDS
) and then it will cut the paper.
–
When sending any cut command to the printer will do the same as above.
–
When sending a
GS FF
command to the printer it will feed paper to the next cutting line.
–
If the printer detects that paper has been fed for a distance larger that the ticket length without
having cut the paper, it will pop a black mark error.
–
The first ticket should be discarded since the printer cannot estimate the distance to the next
cutting line until it has detect at least one black mark.
