3.4 Paper Thickness Detection Sensitivity Adjustment and Media Thickness Detection
Value Check
Outline:
The sensitivity of a micro displacement sensor used for detecting media thickness varies from
one to another. Therefore, to ascertain the sensitivity in advance, check the output value of
the sensor by passing media of known thickness through the printer equipped with the sensor.
The sensitivity is fixed based on the output value.
Adjustments must be made when the paper thickness sensor, the registration roller and the
PU board are replaced.
By passing, from the multipurpose tray, four sheets of paper whose thickness has been
measured with a micrometer (MDQ-30M, MDQ-30), the correction value for media thickness
sensitivity is automatically set with the first three sheets. Check the media thickness detection
value with the fourth sheet.
