5.1 Print mechanism
Major adjustment of the printing mechanism beyond format-based
settings is only required if the printhead assembly has been removed
or parts in this area have been replaced. Excluded from this is the
replacement of the printhead, after which readjustment is generally
not required.
The following print quality imperfections may indicate maladjustment
of the printing mechanism:
•
Print image too light
•
Print image is spotty
•
Print image lighter on one side
•
Horizontal lines not parallel to the horizontal label edges
•
Clear lateral drift of the transfer ribbon
Print image errors can also arise from wrinkling of the
transfer ribbon. This is why the transfer ribbon feed path
and the head locking system should be checked before
making adjustments to the printing mechanism (see
'operating manual'
).
Adjustment of the printing mechanism encompasses the following
procedures in the order specified:
1. Adjust position of printhead (see chapter 5.2, page 28).
2. Adjust the ribbon feed path (see chapter 5.4, page 32).
3. Adjust the ribbon rewinder/unwinder (see chapter 5.5, page 33).
4. Adjust the printhead photocell (see chapter 5.6, page 34).
