Replacement Procedures
Laminator Sensor PCBA
Functional Test of the Sensors
Step 1. From each of the laminators, upper and lower, remove the transfer guide and the
laminate patch, if any, beneath it.The laminate sensor should read high, around 250.
Step 2. Replace the guide, and the laminate sensor should read no lower than 180. If lower
than 180, move the sensor board away from the transfer rollers, to the left; see
diagram below.
Step 3. Complete the test by running laminate onto the rollers (press the
LAMINATE
button). The laminate sensor should read below 20. Adjust sensor board to correct.
Note • The sensor board must be symmetrically positioned relative to the transfer rollers,
with its attachment screws central in their slots. It is possible to get a false “good” reading if
the sensors are too close to the feed rollers.
