Ricoh B230 Service Manual page 182

This belt must be installed the correct way around. When you reinstall the image
transfer belt unit, install it with the painted number [D] on the belt at the rear side of the
unit.
Put "Lubricant Powder" (B132 9700) on the surface of the image transfer belt [A], while
you turn the drive gear [B] at a constant speed, as shown. (The straight arrow in the
picture shows belt movement direction.) Lubricant powder prevents the image transfer
cleaning blade from turning up.
Do not put the lubricant powder at the right side of the image transfer belt unit
(the above picture is taken from the rear). Otherwise, lubricant powder may
damage the encoder sensor.
