Sensor Replacement

98
Before deciding to replace the sensor, check that the sensor is free from
dust, and other objects that can block the light.
Replace the sensor as follows:
• Switch off the power, remove the power cord, and remove the front/
left-hand cover.
• Raise the printhead.
• Disconnect the sensor's cable from the CPU board.
• Pull the sensor straight out using a pair of pliers. The sensor has a
barbed shaft inserted into a hole in the center section moulding and
requires some force to come out.
• Make sure the hole is clear from any remnants of the old sensor.
• Reassemble in reverse order. The sensor's cable should be connected to
J58 (marked "HEADLIFT") on the CPU board.
• In Fingerprint, check that the sensor works properly using a PRSTAT
statement, see Intermec Fingerprint v8.xx, Programmer's Reference
Manual.
• In IPL, check that the sensor works properly using the Label Path
Open Sensor Value (<STX>L<ETX>), see IPL Programming, Reference
Manual.
