Vertical Registration Adjustment; One-Sided Thin Original Mode - Ricoh A172 Service Manual

15.18 VERTICAL REGISTRATION ADJUSTMENT

15.18.1 One-sided Thin Original Mode

Perform this adjustment for machines having problems using the Thick
Original Mode as well.
The original stopping position in thick original mode depends on the setting
of this adjustment. (For details, refer to Detailed Descriptions.)
NOTE: 1) After replacing the DJF main board, always perform the
adjustment using VR101 on the DJF main board.
2) At other times, adjust with either the base copier SP mode or
VR101. Both procedures will move the original stopping position.
3) After finishing the adjustment, be sure to turn off the dip switches.
