Drum blade pressure release screw ?

[sbillis]

Hello there.

can anyone tell me please what the 2 screws do at drum du-102 blade pressure release?

Yesterday I forgot to remove 1 of them (front) on a new installed drum at km6500!
I power on the engine and I 've did initial drum rotation, Toner Density SensorInit, Blade setting mode, Auto gamma adjustment and Color Registration Adj.
After these steps I made a test colour copy with no errors.

I can sleep now... Monday morning will be first thing to do !
What can cause this terrible mistake ?
Can destroy the drum? Or can be produce dirty printouts?

Thanks and sorry for my mistake !

They keep the blade off of the drum during shipping. You may get 1-2K copies before noticing copy quality issues.

The old image will not be cleaned off very effectively, and you will get ghost print. You have to go back and remove the screws - the red ones
