Length detection 2
Length Detection 1
When the cleaning belt length detecting flag comes into contact with the cut-off (300 mm from
the end of the cleaning belt), the cleaning belt length warning sensor (PS8) detects the flag,
causing the message "Web Running Out" on the control panel. (Copying may continue.)
If copying continues after detection by
PS8, the flag moves farther down,
causing error code E005 upon
detection by the cleaning belt length
sensor (PS7).
Reference:
After the message
“Cleaning Belt Run-
ning Out” has ap-
peared, about 15,00
copies (A4) may be
made. (In the case of
A3, about 7,500 cop-
ies.)
