Descriptions
Because the cleaning roller is metal, it can collect adhering matter better than the pressure
roller, which is coated with Teflon.
6.13.6 HOT ROLLER CLEANING
Overview
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 [B] and web take-up roller [A]. The web motor
switches on for 0.3 to 10 s at 8.4 s intervals during printing.
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 90% (EU) or 92%
(Asia/NA) of the web has been used, which is about 144 K: EU, 147 K: NA/ASIA (A4 LEF).
