    [Error Code] MP4000/5000 SC324 Errors

    Hello!

    We've had ongoing problems with the dev units seizing on these bags of poo, throwing up SC324 errors. This isn't so much of an issue whilst the machines are under warranty (other than the inconvenience to the customers of course) but, once they are 12 months old, we begrudge paying through the nose for new units when there is obviously an inherent flaw in the design of these things.

    Does anybody have any idea why this fault occurs and whether there are any preventative measures which can be taken to stop this?

    Ta very much!

      SC324 is a problem with the Development Drive. I had this twice - in each case the DV unit was broken. It seemed that toner/dev spilled into the (front side) area housing and blocked the gears - probably a bad bushing-seal. All in all this is more a rare phenomen compared to the ongoing tonder/mag roller issues.

      PM me if you need a service manual.

        The MP4000/5000 isn't the best machine Ricoh ever built but I've never seen an SC324 error on these machines. There are some issues with development units, but these result in dirty background on prints. I can't find any RTB's on this issue. Are you using the original toner?

          Yeeeees. Or, more accurately, no. To have never seen an SC324 is good going, we've had loads of them and we don't have too many machines out there thanks to the MPc range.

          As far as the gears in the front of the dev unit go, none of the machines which I have been to have displayed a leaking of toner into this area, although TonerMunkeh did suggest this to me in the past. And so the mystery continues.

          Regarding the quality issues, I've been using the B079 dev, toner and toner motor thing as per the suggestions here with good results thus far.

            I've seen this last week, I've got two machines at a hospital, both MP5000's that get absolutely caned. One showed SC324 within 400k, followed by either 220 or 222 (can't remember the exact one). The 22x SC was caused by the laster unit being drowned in toner, from the from of the dev unit leaking. The only fix, unfortunately, is replacing the entire dev unit. The only thing I can think of that would possibly help is completely cleaning the dev unit out, vac'ing and blowing out with air on every dev change. The modified dev units with the extra filters seem to help a little too.
            It's 106 miles to Chicago. We've got a full tank of gas, half a pack of cigarettes, it's dark and we're wearing sunglasses.

            Hit it.

                Thank you, however I know what the code is and how to fix it. I was after a way to prevent it from happening again.

                I don't mean to sound ungrateful, by the way!

                  I think you can't du more than swapping the entire dev unit. We have ~60 - 75 MP4000/5000 in the field and asfar as I recall this issue occure twice. Both machines didn't had a lot on the counter so I guess this is more a lack of quality-control during the production.

                    Thank you all. Sc 324 for me today. Problem due to the bearing of the development group. Obviously not included in the parts catalog.

                      I cleaned dev bearings with brakes cleaner and lube it with silicone grease. Works like a champ.

                          I am having this issue. I removed the corroded seal and used silicon grease and cleaned with a q-tip. works great....... for a few months..... The degraded seal is what is causing the lock and once the seal is out completely, it will work for a short while but then it will get packed with toner. I just got a call back for this MP 4001 and it has a DV unit lock again. My customer is a small business so they can't afford a whole new DV unit. I have decided that I am going to go in with a thin piece of rubber and an exact-o knife and grease to recreate the seal. I will let everyone know how this works tomorrow.

                            I have had seized dev unit before and although the part for the bearing is not in the manual it can be obtained. (From a bearing supplier)

                            There us another thread on these bearings and gives the part number.

                            If I find one of our spare bearings I will repost with bearing details.

                            Good day.

                              The bearing number is: 6901-2RS-C3

                              You can get 10 for about 15 quid.
