8-3 Adjusting the Paper roll Holder Unit

It is necessary to adjust the paper roll holder for the width of the paper you use.
If the setting position is incorrect, the paper roll will be supplied improperly to the mechanism which in turn
causes paper transport problems. Thus, it is should be properly adjusted.
Note 1) The unit is assembled for 1 inch paper cores when shipped from the factory. Also, it is set for a
paper width of 111.5 ±0.5 (take-up width of 112 +0.5/-1) when the printer is shipped from the
factory.
Fig. 8.3 A is a reference for the paper roll holder unit paper roll shaft position. Adjust or mount the paper roll
holder unit for the core diameter and width of the paper you intend to use.
Also, the reference pitch is 2 mm. Therefore, to handle any type of paper, position the paper roll holder
according to this reference.
The following table shows the paper roll holder and paper core inner diameter range.
