6.16.6 OIL SUPPLY AND CLEANING
[B]
⇒
The oil supply and cleaning web [A] feeds the web felt soaked with silicone oil.
Springs [B] hold a roller under the web [C] against the hot roller [D].
This intermediate roller applies a light coat of silicone oil to the hot roller and
removes paper dust and toner from the hot roller.
A spring clutch inside the mechanism pulls the web to take up the slack, to prevent
it getting pulled in between the fusing rollers.
At prescribed intervals (see below), the web motor [E] switches on for 2.8 sec. to
move the oil supply and cleaning web felt.

the motor rotation time and rotation interval. SP1902 004 (Web Motor Control -
