Hey everybody. Making loud squeeking noise from drum unit area. Any ideas ?

[mabawser]

has the blade flipped?

Have you lubricated the drum with toner/powder before putting it back in?

Thanks for response. Yeas. Lubed.
With orig. drum & blade & without.
No it has never flipped. Yet. I have this with 2 Mach. On 1 I moved blade to middle of blade retreat lever till it stopped whistling. I was doing it with doors open during copying. Someone told me it must be in drub drive.

Try a different blade, some just do not work. I have had bad luck with aftermarket blades from Viet Nam.
