Ricoh 240 w error code 300-1

[Rick]

This machine occassionally spits out a 300-1 error code I cant seem to pin it down . Any ideas anyone .

It's a charge error and can be related to the corona itself shorting, the power pack or the toner door switch...and possibly the NVRAM. Hope that helps.

Replace your main charge wire , and clean and or replace grid wires also ( 4 grid wires )
