ADJUSTMENTS

4. Adjustment of Colour Ribbon Holder (Colour Type only)
This adjustment requires use of the carriage unit to fix the position of the color ribbon holder on older parts (see drawings
no. 1-24 and 1-25, chapter 7, part 3-3-2). However, newer parts (nos. 1-30 and 1-31) do not require use of the carriage
unit.
Adjustment of the colour ribbon holder properly positions the ink ribbon cartridge vertical to the print head when the
cartridge is installed on the colour ribbon holder. (Refer to Fig. 3-10.) Failure to perform this adjustment may cause some
kinds of defective printing such as printing in “YELLOW” ink when printing should be done in “RED” ink.
The following is the adjustment procedure.
(1) Execute Self Printing [1].
(2) Judging from the print sample printed just now, decide if the ink ribbon cartridge should be moved upward or
downward of the print head.
(3) Remove the printer cover and ink ribbon cartridge [1] .
(4) Turn the adjusting screws A [2] and B [3] (brass parts)
counter-clockwise to move the ribbon cartridge upward.
clockwise to move the ribbon cartridge downward.
(5) Install the ink ribbon cartridge and printer cover.
(6) Execute self printing.
(7) Check the printing condition on the print sample.
If additional adjustment is required, repeat the procedure from (2) to (7).
