CHAPTER 5. SECOND PAPER FEED SECTION
Adjustment
1. Gap Between Timing Roller and Guide Roller
Check and adjustment procedure
(1) Rotate the paper drum until the cam on the guide roller gear is positioned as shown in the
diagram.
(2) Check that the gap between the guide roller and the timing roller is 1.0 mm ± 0.25 mm.
(3) If the gap size falls outside these specified values, loosen the guide lever ass’y lock screw and
adjust.
(One graduation on the section marked “
A ” on the sketch below corresponds to a gap variation
of 1 mm.)
* If the gap is too largely off from above value, it is recommended that the graduation scale, pointed
out as “ A ” on sketch below, is adjusted to the center line. This will bring the gap close to 1 mm.
* Make sure to readjust the “Gap between paper pass guide and lower paper guide” (given on next
page) after adjusting the gap between the timing roller and guide roller.
