Try to check if the Developer is sticking on the drum if so, Check the bias of the DV or test other DV unit. If you have HV try to test it also.

Yes there is a slice of dev on the drum (inboard),regarding
Hv unit is it hard to replace?

Hope this will help if it is hard to remove?! No pain no gain...

It's not as hard as some of the newer series machines power supplies. But it's behind another board as the illustration shows.

Good luck.
