8.3. Fastening the Friction Spring

It is necessary to adjust the friction spring position for the width of the paper you intend to use. If the setting posi-
tion is incorrect, the roll paper will be supplied improperly to the mechanism which in turn causes paper transport
problems. Thus, it is should be properly adjusted.
Notes:
1. After adjusting the position, slowly turn the roll paper to check that it turns smoothly.
2. It is necessary to make fine adjustments to the friction spring position according to the
roll paper material.
