GGRRRRR...
I went to a machine yesterday where the customer was complaining of a loud grinding noise.
Sure enough on arrival I could hear the sound of a motor trying to drive stationary gears..we all know THAT sound.
The machine wouldn't make the sound with the right hand door open and would boot quietly to a ready state just prompting to shut the door.
Of course..as soon as the door was shut the motor would try do drive the gear and BBBRRTTT...back comes the noise.
Now for the good part...
I tried to pull out the process unit to inspect for damage to the drums/and or ITB assy.....STUCK....absolutely going nowhere..!!!
I spent two hours on the machine with no joy.
Today I relented and called another tech to the machine coz I needed another pair of eyes/hands. and we spent 8 hours onsite..
We eventually found what caused the issue in the first place...the rubber rib that runs around the itb belt had come off(the belt was still in place and had been working up to this point)and had fallen into the yellow drum unit.
It became wedged between the drum and the blade so tightly that the drum stopped rotating..hence the drum drive motor was trying to turn a seized drum.
To free up the process unit we had to remove the main controller,DC controller,DC drive pcb,all night power supply and the complete ITB/Drum/dev drive assembly and then the process unit popped open.
We replaced the itb assy as well as four new drums....wait...it get's better..
We booted up the copier and were presented with "Load new Black drum"...new yellow drum...etc etc...the machine did not know that it had a set of drums in it.
There are a few techbase articles about this issue so we went through them one by one til we exhausted all avenues.
Meanwwhile I've spent a day and a half on this machine at the expense of my other customers who are struggling to understand why I keep fobbing them off.
So I told the service manager today he'll have to give them a replacement machine and get someone to work on their machine back at the workshop...I've wasted too much time on it already.
As it happens the customer is already pissed at Canon due to the numerous "0212" buffer pass jams that this...and many other 3380i seem to be riddled with.
In a medium humiditiy environment these machines curl the paper so badly that it jams at the buffer pass exit/finisher swing guide entry.
I had only just sorted it this week when BLAM...the machine completely craps itself...the machine is only 50,000K old.
Shades of Irc3100 here I'm afraid.

At least you now know more about the machine than is probably healthy
