Adjustment To Make The Bp Unit - Riso ComColor X1 series Technical Manual

3-3. Adjustment to Make the BP Unit and Registration Roller Parallel
<Adjustment Overview>
If the BP unit and registration roller are not parallel, when the registration roller transfers a sheet aligned on its
leading edge to the BP unit, it will be transferred crooked, causing misalignment of lines in portrait orientation as
CYMK inks are applied in a sequence with the ink drop position off. This adjustment is designed to correct this kind
of problem. It is a required adjustment after replacement of the BP unit, transfer belt, or suction fan.
<Adjustment Instructions>
For adjustment instructions, refer to Chapter 11A on the subject of "Transfer Unit Position Adjustment" and
"Registration Roller Position Adjustment*.
