4.3 DEFAULT SETTING PARAMETER REGISTRATION
The
set up value that specifies the destination of the product distribution, is stored
in
the
EEPROM
on the main board (C106 MAIN). Therefore, this set up value must be written in
EEPROM
when the
main board or the
EEPROM
chip is replaced.

4.4 PAPER GAP ADJUSTMENT
When the
printer mechanism is disassembled to remove and/or replace the carnage unit, the
distance between the
printhead
and a paper surface (Paper gap) should be adjusted to 1.0 mm, to
ensure the print quality.
[Step 1] Attach thepapergap
(PG)
gauge
attheleftside
adjust position shown in figure below, as
the top edge of gauge contacts a support plate of FRAME ASSEMBLY, BASE.
[Step2]
Move the carriage to the position where the PG gauge is attached, while lifting up the
front edge of the carriage as to widen the gap between the
printhead
and the mechanism.
[Step3]
Carefully put the carriage on the
PG
gauge and verify that there is a gap between the
front edge of the carriage unit and the front frame.

bush 1 step in reverse direction.
Remove the PG gauge and attach it at the right side adjust position.
Repeat the step from [Step 2] to [Step 4], and adjust the gap with BUSH, PARALLEL,
