Reinstallation
After you replace the drum:
! Do SP2923 (Cleaning Blade Replace Mode). This applies toner to the drum and blade
to decrease friction between the drum and the cleaning blade. If you do this, scratches
on the drum or a bent cleaning blade are less possible to occur.
! Do SP3001-2 to initialize the ID sensor.
! Be sure to tighten the hexagonal lock screws in the drum gear.
