You could try and reset in service mode yourself.. try this press the yellow clear button above the number pad then enter 107 then hold down the stop button for about 5 secs .. the screen will change then turn off the machine and wait 5 secs turn back on.. Im not sure why you are getting teh code 305 as this machine doesnt have a corona wire cleaner.. is the code correct?.. good luck

    Sorry missed the link back if its the 1224 then the connection on the charge grid down at bottm left of the pcu is either disconnected or faulty it looks like a lj 45 phone connector and the port is to the top right under the handle for pcu.. you coulld also take the coroner unit out and clean the grid with some soft brush there is a screw which holds ot down in place its usualy plastic on theese so dont loose it th wire can be cleaned with a bit of scotch bright but do this gently you might see a build up of toner on there as its under the cleaning unit for the drum cleaner and the devs drop toner on it as well.. once you have cleaned it make sure it sits back in proerly and if you need to reset the code do the clear 107 then hold the stop till sp mode show and you need to go to mode.5 then 810 for sc reset.. goood luck A

How to solve this problem sc 302

I managed to find a list of Ricoh error codes with brief explanations of their causes here:
Ricoh copiers error code messages

This clearly identifies the problem as a laser motor problem - OR
Charge roller, HVT, or fuse FU5 (AFICIO 340, 350 series, 355, 450 series, and 455) - OR
SC-302-01, 02, 03, 04 Charge corona assembly Aficio 550/650
SC-303 Charge corona wire cleaner, disconnected or time out for printer.
All of these sound rather like an engineer requirement but you may be able to something with appropriate spares

Error code E000069-0000

Error code E000069-0000: "corona transfer error"
This is an error regarding a problem with the transfer corona, it seems you had a high voltage spike on your machine, causing this error.
There are different causes for these errors, one of the most common is the dirt on the transfer corona to become operational will provoke "jumper" between the contacts.
What you can do is to spray air above the corona to remove the toner accumulatedand if the fault still need to clean more thoroughly.

Note: The corona tends at times to fail randomly.
