(1) Set the paper thickness lever to the right and place the gap gauge at position B.
(3) Set the paper thickness lever to the left.
(4) Loosen screw A until the carriage guide frame moves forward under the carriage's
own weight with screw B as a pivot.
(5) Lightly push the screw A end of the carriage guide frame once or twice and check
that the carriage guide frame moves around screw B as shown by the arrows.
If it does not return to the original position, screw B is too tight. And if it moves on
the screw B end as well, screw B is too loose. Refasten the carriage guide frame
lightly again and repeat the procedure from C- 1)
(7) Put the paper thickness lever to the right and move the carriage to position A. Then
place the gap gauge at position C.
