IMPORTANT
Mount the PW sensor assembly onto the ribbon
mask holder groove, aligning the bottom line of
the micro photo sensor with the bottom line of
the groove.
Whenever you remove the PW sensor assembly,
clean the surface of the sensor by wiping it with
a soft cloth. If the PW sensor is not clean, the
printer may operate incorrectly. For example, it
may print on the platen surface.
The tightening torque for the CB screw is 0.08 -
0.12 Nm (0.8 - 0.12 Kgf-cm).
