SC681

Error SC681-xx

I've run into this a few times on the '03 and '04 midsize color machines. I know there is a bulletin regarding the bottle lock spring but I've also found another cause for this error. Each chip on the toner bottle touches a board (PCB:TCB) at the back of the machine. I've found that when this error occurs the PCB:TCB is usually covered in toner. Specifically, the solder joints on the back of the harness connector face towards the bottle. I suspect the toner might be shorting out the connector. Usually, after I clean the board I will seal it with hot glue. I've not had any return for this error after the repair was made. I've attached photos of the PCB:TCB and the steps taken.

Re: SC681

I have usually found that one or both of the contacts on the post is damaged.

Thanks for this one. I am going to try the hot glue thing, as I have intermittent 681's on my equipment too. How involved is removing the little PCB from the machine for the mod?

It's not that difficult. Once you swing the controller box out of the way the toner bottle motor and PCB:TCB are right there. 2 screws for the motor, 2 screws for the board, and loosening the harnesses to get the motors out of the way.

Re: SC681

Ricoh states that outside RF interference is also a cause for this code. I bet that covering those solder joints with glue will also help out with that.

Just had this problem. Damn good info. Thanks for the help.

Thanks for sharing!

Re: SC681

I tried the hot glue mod on a C4503 that was coding for all colors. It fixed all codes but the one for magenta, so it does work.

Grazie, if it happens to me, I'll try

Re: SC681

One thing I failed to mention in the original post is that I don't carry a hot glue gun. I found that a cigarette lighter and a glue stick work really well. It's compact and doesn't take any time to heat the end of the glue stick for use.

For those non smokers, a soldering iron also works. It also allows you to tack weld broken plastic parts to hold them in place while applying the hot glue.

Re: SC681

very good tip, I'm suffering with these codes here in Brazil!
