4.4.4 Carrier and Platen Position Adjustment
Check:
There must be no missing parts of characters when printing, and
the intensity of the top and bottom halves of printed characters
must be equal.
Adjustment:
1) Enter adjustment mode. (Refer to 4.3.3 "Carrier and Platen
Position Adjustment Mode".) (Adjust the printing impression so
that characters are printed faintly on the paper (so that they can
be checked).)
2) Print vertical lines and underlines (or any characters with width
or height.)
3) Insert a flathead screwdriver into the rail slide hole (1-A) and
adjust the rail slide (2) position so that there are no missing
parts of characters and so that the top and bottom halves of the
characters are printed with even intensity.
If the top halves of characters are faint:
Move the rail slide (2) up.
If the bottom halves of characters are faint:
Move the rail slide (2) down.
4) Confirm that all characters are printed and that the intensity of
the top and bottom halves of the characters is even.
5) Turn the power switch off and leave adjustment mode.
Original version PCB (999-32300)
The printing impression is returned to the factory (initial) setting.
If the printing impression is not appropriate, change the short pin
connection for SW202 on the control PCB. The printing
impression can be changed through the software.

Note:
If the intensity of the top and bottom halves of characters can
not be made even, move the adjustment plates (3) located on
the left and right sides of the carrier box.
If the top halves of characters are faint:
Move the adjustment plates (3) down.
2nd version PCB (999-35810)
