y
Clean print roller with dust-free cloth and cleansing liquor only.
y
Rotate roller stepwise for complete cleaning.
CAUTION! - Never use knives or objects with sharp edges for cleaning.
y
The feed roller and the friction rollers are also to be cleaning from time to time. Avoiding any
type of contamination in the printing area generally increases performance of the printer and
particularly the print head.
y
In addition, neat printing results are preferable to poor ones in any case.
y
Put print head to former position and fix screw again.
Note: The screw enters a non visible gap at the axle, which ensures the correct
position of the print head. Factory adjustment is flash with the inner black plastic
bushing.
y
Before switch on the unit, check that both connectors of print head are still plugged on
correctly. Reconnect if necessary.
4.6.3 Cleaning of foil guiding parts
Adhesive residues are to be removed at regular intervals upon processing of self-adhesive
material to ensure perfect print quality. Clean parts with dust-free cloth and cleansing liquor
only. Contaminated parts affect the feed of the foil and will reduce the print quality.
4.6.4 Dispenser maintenance
720 can be easily maintained and has only a few wear parts. If you change the material, note if
any glue or waste labels are stuck on the rolls or dispensing edge. In this case you have to
clean the respective parts. The machine has to be cleaned at least once a week. Glue and
waste labels have to be removed from the rollers, the dispensing edge, the material brush, and
possibly from the applicator. All rollers have to be cleaned from any grease. We will supply a
special cleaning set for this. The material label sensor has to be cleaned from dust regularly.
The material brush should be turned around whenever the material is changed. Any glue has to
be removed from the brush. If there is a soft roller at the dispensing edge for applying the label
to the product, check if the roller is damaged or dirty. Replace it if necessary.
The unwind has to operate in such a way, that the dancer arm does not bounce to its end
position. If this is not the case, the friction mechanism has to checked.
If the backing paper is not wound up accurately, the belts have to be tightened.
CAUTION! - Check the electrical connections, especially the mains cable for
unreliable connection.
