[hknwbec]

I want to ask whish type of ricoh developer suitable for ricoh aficio 1027 copy machine.

[nqk]

type 28
type 26
both are use in 1027.1022.220.270 etc

I would replace the whole PCU, if the devs gone, the drum, charge roller etc will need replacing as well, its far quicker, and cheaper in the long run to replace the whole unit.

[hknwbec]

Thanks for your reply, Could you tell me which is the best type,

[daveyball]

The UK edp code is 412271 PCU TYPE 1027. I'm not sure if the same where you are

Thanks all of you, I use type 28 and change the orginal drum & blade, the copy is OK, may I know what is sp mode for drum replacement or only using developer calibration is enough.

The DV calibration is all you have to do. If you replace the whole PCU as a supply unit, the machine will automatically detect it and run the calibration.
