PRINCIPLES OF OPERATION
Printing Area
The printing area is defined as starting 23 phase-switching times following the home position.
Acceleration Area
NOTE:
pps = pulses per second
dpi = dots per inch
Abnormal Carriage Operation
This unit does not employ a print timing signal (PTS) sensor and cannot detect abnormal carriage operation.
Therefore, no error occurs even if carriage movement is prevented by external forces. An error occurs if
the HOME signal is received in the printing area, in which case the carriage stops.
