How do I enter Service Mode on a Ricoh C900 printer? I'm showing SC241, but can't find it in the service manual... does anyone know what problem that is referencing? Can it be cleared in Service Mode

I have tried Clear Modes / 1 / 0 / 7 / Clear / Stop, but I think that's out of sequence. I can't find the solution in any of the Tech Manuals I have. When we reconnected the unit to show a potential buyer, we had two wires reversed on the box on the back, where the rip is located. The LCD screen was black until we switched the wires (The IKON tech had these marked 41b and 41c, but it's actually 416 and 415). When we flopped the wires, the screen worked, but it threw this code. Any ideas, please? Thanks!!

SOURCE: Unable to enter program mode for Sharp AR-C260M Copier / Printer

Solved the problem by switch on press #P Then * then C then *  then 14  This will then ask if to execute the action to clear the service code H5-01.
Will need to ensure that the fuser unit is not causing a blockage on the feed out path as this code is caused by 5 errors / misfeeds in the Fuser unit.

My spare Ricoh AP3800c has decided to show a SC541 warning, I understand that has to be reset in 'Service Mode' is it possible/safe to do this myself? if so can anyone give me an idiots guide to doing it?...


Power off the printer, wait a while and power on back, while the printer is loading, unplug the printer from the AC power source and wait for some minutes before you plug in back and power on. This should reset your Ricoh AP3800c printer. if problem persist, follow the below procedure.

Hold down the two arrow keys and count to 5, hit the enter key, the machine should be in service mode if nor repeat. use arrow key and scroll to machine press enter scroll to data log press enter scroll to pm counter reset press enter, scroll to fuser oil press enter and execute this mod Please. DO NOT GO INTO ANY THING ELSE or you could do serious damage to your machine!! If your machine has a Copy feature expander you must press Clear mode, Press 1-0-7 and then hold down the stop cancel key 4sec. go into copy mode press 7-804-809 press execute button again Please DO NOT GO ANY WHERE ELSE as damage can be done to your machine.

Take care.
