iR5065 / iR 5055 / iR5075 / / /
The machine removes toner remaining on the fixing roller by means of cleaning web (impregnated with silicone oil) to prevent fixing offset.
The cleaning web is taken up by the takeup roller when the drive from the fixing web solenoid (SL9) reaches the web takeup roller drive gear by way of a one-way
clutch.

The length of takeup is determined by the size of the paper used and the number of prints (within a single job).
*1: A4/A4R/B5/B5R/A5R/LTR/LTRR
*2: A3/B4/LGR/LGL
If paper exits in the fixing assembly because of a jam or error, the machine turns on the web solenoid 5 times at time of recovery (so as to prevent wrapping of the
cleaning web around the fixing roller).
