The code is engine start up error "replace engine board, sorry...

sc363 is a yellow PCU error. Try replacing the toner cartridge and resetting the PCU. If the error comes back, you'll probably need to replace that yellow PCU.

replace the black pcu(drum unit).
the life of the pcu(s) are 15k each(blk & col) .
the machine will work but copy quality will reduce and the error will be there.
replacing the cartridge has nothing to do with this error.

The PCU is the photconductor unit. There is a black pcu and a color pcu. Did you replace these or replace the toner cartridges??

I have had a problem like this before and had to replace the black pcu.

That crosses over to the Lanier LP226cn.

Most of the time when I find this happening on a printer, not just Ricoh's it turns out to be the PCU (photo conductor unit). The color PCU is one unit and the black is a seperate unit. Hope this helps.
