08-153
« on: October 10, 2007, 02:10:15 AM »
Got this DocuTech with a 08-153 problem. Jams every 3000 prints. An unwrinkled piece of paper under the registration sensor.
NOW, if I prop open the front door, and cheat the interlock it won't jam at all.
Something overheating??
I have done the following.
New Lift Solinoids, no help
New Registration Sensor, no help
New Cross Roll Assy, no help
New Cross Roll sensor, no help
New PHN DIO #2, no help
New Registration Servo pwb, No help
Customer is currently running the Doc with the front door open.
ANY IDEAS??

Teh cross roll sensor be sittin down too low man or teh cross roll reflector is scratched.  Jack the sensor up a couple mm's.  Scratched reg guide possible.  Yup   :mrgreen:

try increasing the pressure on the pre reg transport - are the orange rollers worn or gone soft underneath?
is it only from 1 specific tray or all trays , maybe only from the duplex transport - do the ski's lift off cleanly.

best of luck.

This problem only happens in SIMPLEX ( have never seen any paper on vertical transport ) and from any paper tray, BUT remember, the machine won't jam if the front doors are open.

In the past the friend of mine had a similar problem , and related me that if the engine runned without the rear covers , no jams was declared  and  replaced the cross rooll motor solved the problem.
Try to change the  assembly  with other machine.

Hi JHOTA,
I changed the cross roll Assy with another machine and it did not help.
I was wondering if the tray 3 transport sensor would cause this problem.
I think the paper is timed from tray 3 transport sensor to the reg transport sensor,
I might relace that just for grinns.

Door interlock switch?

Check paper tray timing and leave it running to see if it starts to drift off. If so, possibly reg servo motor getting hot?

I would try that Door Interlock...


I would open the door and stick a cheater in the door interlock instead of the service interlock and see if it does it. That would tell you if its the interlock, If it does it now with the door open and the door interlock being used then thats the problem.


At least someone else is finally getting a wierd problem =)  I was tired of being the only one :)

Hi

My other  dumb idea , i had only twice time the  MOT 1217 PL 7- B 12- (4), was dificult to see the belts slowly,   the shaft of motor was  turn slowly some times with jams in the area.

All godd ideas,
I usually just cheat the regular door interlock. Not the service interlock.....I will try that.
I went in today and replaced the tray 3 transport sensor with another one ( not a new one).
I also went into paper feed timing, 08-153....it was way off, I adjusted it to 0.
I did not have enough time to stick around for 3000 prints. I ran probally 1000 and no 08-153.
Time will tell.

Just called my customer , night shift, and he said that he has had 3 08-153 with the door closed.
He opened the door and cheated the door interlock and he has had none.
So, anything I have done has not helped.
Gotta be something heating up. If it was an interlock sw, just cheating it or door closed would be the same, interlock closed by door or cheater.

Any ideas?????       :|
I also had my customer unplug the left lift Sol and run the machine and he said it ran fine, so that rules out overheated left lift sol.

Sounds like an optical sensor is being affected by light with the door open. I once heard of a 10-101 that was fixed by replacing the prefuser sensor. It also only happened with the door closed.

I'm wondering if it could be the Registration Transport servo motor heating up causing the 08-153 ?
Any thoughts?

Danny,

I like the sound of Wilbur's suggestion... Try checking your collector voltages at the dio with the door open and closed. I've had a top tray sensor in the past not want to reset when taking out the prints yet I could reset it by pointing my flashlight at it. Photons are funny!
I really doubt the difference in heat would affect the motor.
