Monitoring functions

While in dispensing mode, an electronic control
monitors the following functions:

Missing labels

A label missing from the label roll does not normally
affect the dispensing operation, because the label feed
continues until a label’s edge passes under the label
sensor.

Nonetheless, it can be important that missing labels are
reported. By configuring the function

LABEL SETUP

>Missing Labels,

you can specify whether an error

message is triggered after one or several missing
labels.

Recognising the end of the label roll in
advance

If the end of the label roll is to be recognised prior to the
last label being dispensed, it is recommended that a
sensor is used to check the outer diameter of the roll.

This sensor, which is available as an extra, is mounted
on the unit in such a way as to trigger an error message
as soon as the roll’s diameter falls short of a specified
value. This diameter can be configured.
