Detection block: Position sensor (HP-131 board)
Contents:
A thermal head does not reach the home position, tray position, media transport posi-
tion, or print position during head motor rotation.
Possible cause 1: Defective head position motor, SU-114 board, or position sensor (HP-131 board)
Possible cause 2: Defective connector (CN403) on MEC-33 board and defective connector (CN1) on
HP-131 board, or defective harness connecting these connectors
Detection block: Cutter position right/left detection switch (cutter unit)
Contents:
A cutter cannot be moved to the initial position (the left) during initialization of a
cutter position in mechanical reset.
Possible cause 1: Defective motor or switch of cutter unit
Possible cause 2: Defective harness connecting the connectors (CN203 and CN402) on the MEC-33
board and a cutter unit
Possible cause 3: The movement of a cutter was disturbed due to the internally remaining print paper.
