Intermec EasyCoder PC41—Service Manual
The peel-off mechanism is hinged to the base frame moulding. It has a
spring-loaded idle roller that is pressed against the platen roller, when the
peel-off (self-strip) mechanism is closed so the liner is pulled down over the
peel-off bar, which causes the labels to be separated from the liner.
The peel-off mechanism is fitted with a label taken sensor, which is used to
halt the printing until a printed label has been removed.
The label taken sensor consists of an LED and a photoelectric sensor with
an on/off switch. The light from the LED is reflected back to the sensor by
the back side of any label or similar that remains to be removed from the
outfeed area. The sensor triggers at 4V, which must drop to 1V before the
sensor changes its state. The same circuit board is also used as for ribbon
detection.
The peel-off mechanism comes as a complete unit including the label taken
sensor.
• Disconnect the label taken sensor cable from J10 on the main board.
• Disengage the hinges from the inner walls of the base frame moulding
and pull out the peel-off mechanism.
• Install a replacement unit in reverse order.
