When you replace developer, make sure to clean the waste toner path on the PCU. Waste toner in combination with new developer causes trouble. After replacement of the developer use a piece of paper to block waste toner from falling into the DV-Unit. Then run SP2-801 and do process control.
Then make 100 copies and after that remove the piece of paper. A Ricoh tech told me that the amount of toner in the developer can be very high, so he always made 100 copies before removing the piece of paper. I'm doing this for a long time and I never had trouble with SC's related to TD-sensor.

You need to replace the HDD. It is very simple. Then format it in SP Mode. Reboot. Ready to use.

The machine will automatically reset the maintenance message when the fuser is replaced.
There is a looped wire on the fusing unit connector containing a thermo fuse (a thin wire that quicly melts, and then short the cirquit).

If you don't want to replace the fuser yet, you can probably set the machine to meter charge, SP mode 5930, and then reset the maintenance counter with SP mode 7804.

You can of course take out the fuser, and replace it with a dirt cheap thermo fuse bought from Ebay. Then set the fuser back into the printer, and it will clear the maintenance message automatically.

Either way should work fine, at least it used to do that on the previous model - and it is almost identical.
