UBI EasyCoder 401 Linerless – Technical Manual
The remaining three potentiometers are situated along the top edge
of the CPU board and can only be accessed after the left-hand cover
plate has been removed. Normally, they do not require any adjust-
ment.
❑
Label Stop Sensor Adjustment:
This potentiometer is used in connection with the printer's Setup
Mode for adjusting the sensitivity of the label stop sensor. In
most cases, it will be sufficient to use the adjustment method
offered in the Setup Mode and the Testfeed facility.
❑
Label-Taken Sensor Adjustment
The label-taken sensor is either fitted inside the paper cutter
(standard in EasyCoder 401 LLC) or above the paper outfeed
slot (option in EasyCoder 401 LLT) and 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.
In case of an LTS optionally fitted to the front of an EasyCoder
401 LLT, the light intensity of the emitter can be changed
between two values by means of fitting or removing a strap on
P-607 (strap fitted = increased intensity). No such strap must be
fitted on an EasyCoder 401 LLC.
❑
Ribbon End Sensor Adjustment:
Obviously, this sensor is omitted since the printer is not fitted
with any transfer ribbon mechanism.
Before changing the setting of a potentiometer, always make
sure that the corresponding sensor is clean, free from obstruc-
tions (e.g. pieces of labels or adhesive residue), and properly
aligned.

Caution!
If some adjustment nevertheless
must be performed, it has to be
done with utmost care. Since the
power must be on during the ad-
justment procedure, precautions
must be taken to avoid any risk of
electrical shock or short-circuits!
Use non-conductive tools and keep
fingers away from the CPU board,
especially the area behind it, where
the mains inlet and mains switch
are situated.
