G060R823.WMF
NOTE: To minimize the amount of color shift, the position of the drive gears is
controlled at the factory, to stabilize the rotation of the gears. Before
installing the transfer unit, adjust the position of the gears according to the
procdure below.
1) Rotate the transfer unit cleaning drive gear [A] counterclockwise until
the mark [B] on the transfer unit drive gear aligns horizontally with the
gear shaft [C]. After adjusting the gear position, check the position of the
mark, keeping your eyes at the same height as the mark. Rotate the
cleaning drive gear [A] either clockwise or counterclockwise for fine
position adjustment.
2) Rotate the transfer belt drive gear [D] on the transfer unit clockwise until
the mark [E] on the gear and the centers of the shafts are on a line [F]
which is parallel to the lower edge of the left bracket [G].
After replacing the transfer unit:
• Perform forced line position adjustment (SP5-993-002 or 'Maintenance menu –
Color Registration - Auto Adjust' in User Program mode),
• Print the 1-dot grid pattern on A3/11"x17" paper and check the color shift level
( 4.4.3 Color Shift After Transfer Unit Replacement).
