Chapter 5 - Maintenance and Adjustment
5-1. Thermal Print Head Cleaning
Unclear printouts (some parts unable to print) may be caused by dusty print head, ribbon stain, or label liner glue, therefore when printing, it’s necessary to keep the top cover closed. Also, check and prevent paper/label from being stained or dusty to ensure print quality and to prolong the print head life. Print head cleaning instructions are as follows:
1.
2.Open top cover.
3.Take out the ribbon.
4.Open the print head by pressing the locking tenons.
5.If on the print head (see yellow arrow) there’s label pieces or other stain, please use a soft cloth with industrial use alcohol to wipe away the stain.
Note:
(1)Weekly cleaning on the print head is recommended.
(2)Please clean the print head with the cleaning card that comes with the printer.
5-2. Thermal Print Head Balance Adjustment
When printing with different label materials or using different ribbon types, unbalanced print quality may occur due to the media material differences, thus it’s necessary to adjust the Thermal Print Head pressure.
1.Open top cover.
2.Take out the ribbon.
3.Turning the print head adjustment screws slightly by Philips screwdriver to increase or decrease print head pressure.
