8200 Replaced heater lamps, now paper jams

[OTallOne]

Hi, Hope somone can help. I just replaced my heater lamps in my 8200 and they heat up just fine. I pass all post tests and when it tries to print it's test page, my paper jams. It jams just above the maintenance tray as it tries to enter the rollers just above the tray. With my side covers off, I see the roller shaft doesn't ever turn though the gears on it do. This thing on the end of the shaft I assume is a clutch which I'm guessing either never activates or is no good. The assy for these rollers was taken off during changing of my bulbs, is it possible I didn't get something back correctly? I removed the roller assy again (this is the one with the circuit board on it) and checked the 2 little flippers that appear to be paper sensor switches. They move freely.

Also, please give me the procedure for getting into diagnostic mode, I think from what I've read that I need to flip a switch during power up or something.
Thanks for any suggestions

Remove the metal chrome shield and look on the left side, there is a connector that the upper feed roller plugs into. Sounds as if you may have mistakenly not reconnected it. If it worked prior I doubt that the clutch just suddenly failed, though stranger things have happened.

Thanks for the sugestion Marty but it's very tight. It's so tight that when I took out the assy the wires are attached to that I couldn't get it apart so I left it together and gently dangled the assy by the wires. Nothing looks pulled out or stressed. I figuredout how to get into diagnostic mode and ran the tests. It passed everything until it got to Check Cap Alignment. It said Measuring Cap Backlash, then it stopped and displayed FAULT. Mean anything to you?

I also see that I have the same symptoms as "Printflight" 3 Threads down on the main forum page. I checked my sensors and they seem to be there and move freely.

Next here is what I've learned. I now know how to run diagnostics. In the Field Service Menu, I ran.. I think it was Check Paper Path and I selected "All Tests"

It ran through quite a few things then Failed Check Cap Alignment. It displayed:
Check Cap Alignment
Measuring Left Belt Hysteresis
Cam Release did not occur
Fault R0: 49
R1: 18

Does this mean anything to anyone?

"I then ran Check Cap Alignment" and it failed. When it failed it displayed:
Cap Cycle: 5 Current 0.784
Positioning Cap axis to Max
Abort on excessive lag
Press any key to continue

Reran it and got:

Complete
R0: 0.7840
R1: 5
R2: 0.0320
R3: 0.0000
R4: 0.0000
Help! Still getting front paper jam!

By the way, all clutches and paper sensors at the preheater entrance are working.

Just a quick question, when you installed the roller assembly did you make sure the keys of the brass bushings were in their slots? If one is not in position it puts a bind on the shaft and it will not turn right. Also did you check the long black sensor flag on sensor board?

 

[OTallOne]

There is one brass bushing that goes into the left side of the chassis and must be oriented to fit totaly in the hole. I made sure that one was right. There is only one like that to worry about right? In diagnostic mode, I ran the test that turns the feed rollers and it turned just fine.

On the sensor board I had 2 flags, both white. I have checked them both physically and electrically and they seem to work. Is there a black one I missed? The sensor board you're speaking of is the one just above the preheat feed rollers right?

 

[CULTOFLON]

There are two brass bushings...one on each side of the roller assemble and both must be inserted correctly...on the sensor board assembly (metal plate that the sensor board is attached to and sensor board) there is a long bar that runs from the sensor board to the other side of the metal plate with a flag at the end of it. This flag gets broken very easily...you can see the notch the flags goes into...make sure its not broken.
