REP 3.16 FOLD PRESSURE, TOP FOLD ROLLERS
Purpose
There are two springs on each side of the top Fold rollers, one is stiff and the oth-
er is softer. When running two to five sheets the Fold rollers will only use the soft
springs, when running up to twenty sheets all of the springs will be compressed.
Switch off the main power switch and disconnect the power cord.
Remove Front and Rear cover, according to CRI 2.1.
Check that there is a 35 +/- 0.5 mm space between the fold bracket and the
fold roller arm at the upper spring.
Check that there is 35.5 +/- 0.5 mm space between the fold bracket and the
fold roller arm at the lower spring.
