Potentiometers
The CPU board is fitted with three potentiometers with the follow-
ing functions:
• Display contrast adjustment
• Label stop sensor (LSS) or Black mark sensor (BMS) adjustment
• Label-taken sensor (LTS) adjustment
All three potentiometers are easily accessible after a cover plate on
the printer's rear plate has been removed:
❑
Display contrast adjustment
Using a narrow-tipped screwdriver, turn the screw in either
direction until the text in the LCD display on the printer's front
becomes clearly visible in the prevailing light conditions when
viewed from a normal working position.
❑
LSS/BMS adjustment
This potentiometer is used in connection with the printer's Setup
Mode for adjusting the sensitivity of the Label Stop Sensor or
optional Black Mark Sensor. In most cases, it will be sufficient
to use the adjustment method offered by the Setup Mode and the
Testfeed facility.
❑
LTS adjustment
The label-taken sensor (optional) detects if a label has not been
removed from the outfeed area. Thereby, the printer can be
programmed not to print any more copies before the last copy
has been removed. The operation of this sensor depends to a
large extent on the reflectivity of the labels (e.g. glossiness,
colour etc.). Thus, it may sometimes require adjustment when
switching between different types of labels.
Before changing the setting of a potentiometer, always make
sure that the corresponding sensor is clean and free from
obstructions (e.g. pieces of labels or adhesive residue).
