1-B MG roller main pole position adjustment
1) Put the developing unit on a flat surface.
2) Tie a needle or pin on a string.
3) Hold the string and bring the needle close to the MG roller hor-
izontally. (Do not use paper clip, which is too heavy to make a
correct adjustment.) (Put the developing unit horizontally for
this adjustment.)
4) Do not bring the needle into contact with the MG roller, but
bring it to a position 2 or 3mm apart from the MG roller. Mark
the point on the MG roller which is on the extension line from
the needle tip.
5) Measure the distance from the marking position to the top of
the doctor plate of the developing unit to insure that it is
9.1mm.
If the distance is not within the specified range, loosen the fix-
ing screw A of the main pole adjustment plate, and move the
adjustment plate in the arrow direction to adjust.
