Belt Position Adjustment - Roland VersaEXPRESS RF-640 Service Notes

4-9 BELT POSITION ADJUSTMENT

This adjustment is to prevent the belt wear which is caused by the belt contacting with the pulley Flanges exces-
sively. The belt position needs to be checked after the Belt Tension Adjustment and adjusted if it is necessary.
Revised 2
When adjusting the drive pulley side, the pressure of engagement
between the white gear of the drive pulley and the scan motor gear
is changed, and it leads to a tooth-missing of the white gear or a
failure of the scan motor. After the belt position adjustment, be sure
to loosen the screws fixing the scan motor and re-tighten them
again.
