Re: Ricoh c305

Got it. I'm pissed that the manual doesn't even mention the fuser replacement for this code, just the bicu.

Re: Ricoh c305

Thanks for the pic.

How much did the BICU cost or did you fit a used one?

A lot more that a 1p fuse!

Fortunately I had a spare used one. Wonder if we can use standard Pico fuses (aka the green ones used on komi machines)

Re: Ricoh c305

i made a small kit with a old connector from a thermister and an old small door switch with about 6 feet of thin alarm wire.
I connect this to where that pico fuse wld go and turn on copier and go into service mode and
Enter SP mode and goto SP5810-002.Before you tap execute push and hold the switch in. hit execute and release..
it took me a few tries to get the timing right..
I only did this after mt machine refused to blow that danm pico fuse with a new fuser sleeve...........

Radial lead fuse such as TR5 of the correct amperage should work. Might have to trim lead.

TR5 Fuses - Littelfuse

Re: Ricoh c305

Sorry to dig out the old thread....
I have a similar issue.
My device is Ricoh MPC305SPF.
It has an error of SC544-00. I have replaced a "USED" fusing unit. But the error still displaying. And I have tried the 5810 reset.
But the error still here.

May I know what should I do? I see the previous thread is taking about reset fuse. But I cannot find a reset fuse to purchase....

Re: Ricoh c305

Start a new thread.

OR maybe spend some time reading this one...
the answer is there if you are a tech but i think you might not be..

Re: Ricoh c305

If the sleeve is not damaged just replace SC554 Fuse M0264371

This part seems to be for Ricoh c306. wonder if this part would be suitable for Ricoh c305 as well?

thanks.... have re-study the thread again..
but your way seems to be very technical...

wonder if the fuse can be purchased somewhere instead of DIY one?

Re: Ricoh c305

Does someone have the part number for this fuse? I don't want to try to rig another device into the connector, I just want to have a spare fuse on hand. Thanks.
