1357ex Pro - Constant Functional Problems (SC495)

The engineer doesn't seem sure what the problem is and just and just plugs and unplugs connectors and cleans things out (his words). It then seems to be fine for a while. We've probably had 8 service calls for this problem over the time. I'd guess we get something like 70k between the issues.For example, I have a 12000 run to do. It did 8000 with no major problems but now will only print c150 copies before it errors. As far as I can tell the underlying error code is SC495 (from the data log).Does any one have any idea what the long term solution might be? I can't keep calling them out every month cause it's killing my production capacity.ThanksMichael

To understand better your problem you must know that this code is generated when the toner does not go in toner hoper.So you must start from toner bank to the toner hoper to check everything about toner transport.See the coil if it is rotating first and see the tube if it is in its place,after that you must inspect tubes and pumps one by one.

Thanks everyone, sorry for the delay posting back. Aparently it's a clutch fault. A new one was fitted yesterday but unfortunately the engineer managed to snap a circuit board in the process of fitting it so now I have to wait for that part. I'll let you know if it fixes it.

OK, changing the clutch seems to have done the job. But now there's another problem, which I will call about tomorrow but just in case anyone knows - is there a way to release the toner bottles when the push tabs aren't working? The machine is asking for toner but won't release the lower bottle to allow me to change it.

Thanks

Michael

in sp mode 5804(output checks) there is an out put that will active the toner cap motor. sorrry I don't know the exact sp off the top.

Thanks Tonerbomb. Have done that and the motors are activating, but I still can't get them to release. Will have to wait till they can come in.

If both bottles are empty, it should allow you to remove the bottle that went empty first. Once that one is replaced and in use, you should be able to remove the other.

With the lower rear cover off you can see the rear of the toner bank. You will see 2 white gears on the tonerbank, these gears drive a rack gear that removes or installs the bottle caps. then you can remove the gear and push the rack in to put the cap back in the bottle. Then you should be able to remove the bottles.

I'm Having the same issues, have change the toner pump (D059-3410) and the tube (A294-3475) and the screw that goes in the tube (A294-3477). Still having the same problems, read the someone had changed a clutch which one is it and do you have the part number.

Try the tube (B2343282) that goes from the toner cylinder to the toner pump. The Teflon coating on the inside has probably deteriorated as the tube has clogged. Try cleaning the tube out. If that clears the problem, but it comes back, replace the tube. A quick way to check if clogged tube is the problem, check if there is toner in the toner hopper on top of the development unit (it will probably not be full), clean or replace the tube, run SP 2207-002 (toner bank setup), if the tone hopper is now full the tube was the problem. I have had toner in these tubes compact and clog just by having the tube disconnected from the toner pump while replacing the pump.

Are you working on a Pro 1357ex? If the model you are working on is different, the information you need could be very different than what is listed here.
