Swing back the lower pressure roller and return it to its
position pressing against the feed roller unit. The pres-
sure roller clicks neatly into its operating position.

– The product pulls the label off of the base material.
Synchronise the labelling speed and product speed
(VELO function).

Manually adjust the sensitivity of the label stop
sensor (CONT).
Check the label stop position (STOD).
Check the label distance setting (LPIT).
Check to see whether the feed motor behind the
dispenser head is running.
Refer to E__1 and E__2; First check the loop formation.
