The most common errors, resulting in the excessively rapid wear of the print head are:

* The printing ribbon width is smaller than the printed material width (with liner) – and the part of the label and liner extruding from under the printing ribbon scratch the print head. Saving on the cost of the printing ribbon often causes the mechanical destruction of the head. The printing ribbon should be slightly wider than the label (by 5-10 mm), as the smooth polyester ribbon surface protects the print head from abrasive wear.
*Use of unsuitable labels, not prepared for thermal transfer printing – which increases the print head temperature and results in quicker wear. Thermal transfer printing materials have a smooth, prepared surface allowing the dye to be transferred from the thermal transfer ribbon to the label in an easy way.
* The use of low quality thermal transfer materials
*If the thermal transfer ribbon dye is of low quality, dye dusts deposit on the print head during printing. The same may occur with a good quality ribbon, if it is inappropriately stored after opening and becomes dry.
* If the labels are not carefully cut out by the manufacturer, dust and paper remain on their surfaces and deposit on the head during printing.
* If the labels are too tightly wound onto the roller by the manufacturer, glue escaping from the labels contaminates the print head.
* If the label rollers are stored in unsuitable conditions (e.g. on the floor without packaging), they become contaminated with dust and sand, which cause mechanical scratches on the print head during printing. Such print head damage is irreversible and is not subject to warranty.
* The print head should be systematically cleaned from the contamination deposited during printing, and from dust with use of isopropanol.
