POINT
During reassembly, be sure to route the PF motor cable
through the right cable hook and the right cable holder, as
seen from the rear (see

of the gears.
Gear 67.2 cannot be pulled off its shaft without
deforming it very slightly. If you reinstall the same
gear, its deformation will cause poor print quality in
Microweave mode. Therefore, always replace gear

damage.
