Hot Roller Cleaning
The cleaning web is saturated with silicone oil.
Inside the web cleaning unit, the web take-up roller [A] pulls the web from the web supply roller [B] past
the cleaning roller [C]. The cleaning roller is pressed against the hot roller.
Web Drive
The web motor drives the web supply roller [A] and web take-up roller [B]. The web motor switches on for
0.8 to 2.8 s at 15 s intervals during copying.
Web Near-end
The machine monitors how much of the roll has been fed since it was installed. The setting of SP1902-004
(Fusing Web Motor Control) determines the amount of web remaining on the web roll when the near end
alert is issued. (The default setting is after 80% of the web has been used, which is about 266K A4 LEF.)
Web End
A light-tension spring holds the feeler [C] against the top of the feed roll. When the roll runs out, the actuator
on the end of the feeler [D] enters the web end sensor [E].
