2923 Execute Cleaning Blade Replace Mode
Always do this SP after replacing the OPC or cleaning blade.
This SP applies a small amount of toner to the drum and blade to reduce
friction between the new drum and/or new blade. This prevents scratching the
drum or bending the blade.

2 Enable
If the upper unit remains open for a long time, external light can sometimes
temporarily fatigue the drum and cause horizontal banding in prints. To solve
this problem, set this SP to "1" so as soon as the upper unit is closed, the
charge corona can apply a charge to the drum to correct the problem.
