Ir 7105 shuts down

[Kopyrtek]

Upgraded 7105 to V2 b/c of E733 codes.Now it shuts down in the middle of a run.Has anybody seen this before?All firmware is up to date now and this problem only showed up after upgrade.TIA

Whats up kopyrtec.
The machine shuts down on its own. What about the thermoswitch for now?

SCREWTAPE....How are you doing? Fixing rebuilt less than 20k ago.And yes, it will shut down on it own and show no error codes.Have looked for the obvious problems including drawer connectors and fixing connectors.Now looking to DCon and possibly PS.

Those areas are a good way to start.

I had a 7086 that started getting 733 and 732 codes and I upgraded to V2. Seemed to work then one week later started shutting down after about 1500/2000 pages. The machine just went dead and only the green power light was lit on the display. You would have to shut down the machine and let it sit for a while to get it back up. Replaced the dc controller, and main controller didn't fix it. It turned out to be the harness for the fuser. One of the wires that went to a sensor below the fuser had been dragging on a shaft. Part number for that harness is: FM2-5098-000

Thanks mtech.I will look at that too.Have a ticket with Canon.Will post what i find.

Replaced Dc controller and deck 1.No change until change deck one.Now all seems to be ok.Will post back with any changes.Thanks all for your replies

Fuser recently rebuilt? Make sure the plastic collars/bushings are not installed backwards on the upper fuser roll...if the one is reversed the bearing rubs on the end...you will see aluminun shavings. I've had the cleaning blade vibration motors cause this problem also. If other stuff doesn't fix it unplug the motors

[Kopyrtek]

Well all was well for one day.Looks like it may be a all day power supply or as Canuck said vibration motor in the AP kit.Let you know when they come in.
Thanks for the replies.

We also had this caused by the vibration motor wires being pinched. 733 was first then total shut down with only the green light. After clearing the pinch we had to unplug the machine again to reset it.

[Canuck]

Take a good look at the upper fuser roll collars also. Crack the fuser open and make sure they are not reversed...the reason i say this is because you said fuser recently rebuilt..fuser bias can short from bearing rubbing and chewing aluminum from upper fuser roll.

Had to replace deck 1 with a new one and it seems to have done the trick.Will check the harnesses to see if there is a pinched wire but for now the macnine is up and running.Thanks for all the help guys!
