6) Thermistor Cable at Controller PCA

> One M3x6mm YZD hex washerhead screw at the left rear.

> NOTE the different-coloured torsion springs; the brass-coloured spring is at the left.
12) Torsion Spring Ends
> Unhook them to relax their tension somewhat.
13) Charge Roller Pivot Retainers
> One claw at each. Pull them off.
14) Charge Roller Assembly
> It's now possible to free the left side pivot arm, and then the entire assembly.
> Note the pre-tensioned installation of the torsion springs.
15) Fuser Heater Wires
