PRINCIPLES OF OPERATION
Printing Area
The printing area is defined as starting 22 phase switching times after the home position.
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 will only occur
if the HOME signal is received in the printing area, in which case the carriage will stop.
