8-4 Mounting 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 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) It is necessary to adjust the friction spring position according to the paper roll material. Contact
us for details on fine adjustments.
8-4-1 Using the Spring Base
Fig. 8.4.1 shows the reference marked on the spring holder. Adjust or mount the friction spring 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.
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.
(1) Handling 111.5 mm/82 mm Paper Widths
To handle 111.5 ±0.5 mm or 82 ±0.5 mm paper widths, position the friction spring notch for each on the
references a and a' or b and b' shown in Fig. 8.4.1 A. At that time, fasten so that the central position of
the notch and the central position of the reference do not shift out of position.
Fig. 8.4.1 B shows the position of the friction spring to handle a paper width of 111.5 ±0.5 mm. To
handle a paper width of 111.5 ±0.5 mm, use screw holes A and B and A' and B' to fasten the friction
spring with M3 screws. To handle a paper width of 82 ±0.5 mm, use screw holes B and C and B' and C'
to fasten the friction spring with M3 screws.

to fasten the friction spring with M3 screws.
(2) Handling 79.5 mm Paper Width
To handle a paper width of 79.5 ±0.5 mm, touch and fasten the left and right side friction spring edges
to the boss in the center of Fig. 8.4.1 A. See Fig. 8.4.1 C to make adjustments. Fasten the friction
spring using M3 screws at screw holes B and C and B' and C'.

Note 1) Fit the friction spring between the top and bottom guide rail on the spring base to fasten the
friction spring. At this time, be careful that the friction spring is not riding up on the guide rail
when fastened.
when fastened.
8-4-2 When Not Using the Spring Base
When not using the spring base, (when arranging the apparatus in a vertical layout), it is necessary to fasten
the friction spring to the frame on the user side. Fig. 8.4.2 A to Fig. 8.4.2 C show the recommended layout
position of the high volume paper roll supply (RHU-T900) mounting position and the friction spring. See the
figure to fasten the friction spring.
