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. Power-off the printer.
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.
