Kyocera Taskalfa 6550ci exit unit motor stalls

[carolscurriculum]

Hello I have a Kyocera Taskalfa 6550ci jam code 4211 I found that the exit unit motor stalls I replaced the motor same problem it spins until the paper hits it then stops. could it be a wiring harness or board?

Thanks

That code is for fuser exit jam. Probably would take a look at that.

I have already ruled that out it shows fuser because it cant get past the exit unit the paper stalls the motor. I'm assuming low voltage to the motor but wondering if its a harness or board.

Did you test the sensors?

Yes replaced them all I even replaced the motor The motor locks up when paper hits it. its a power issue.

the exit motor is likely stalling because the fuser exit signal wasn't received during the allowed time. the sensor is within the fuser...

Nope it stalls when I run Maintenance mode 0030 cw & counter clockwise sometimes it starts and sometimes it doesn't nothing to do with the fuser

Power for that motor comes from the engine pwb, through the front pwb. It's a pulse motor, so checking drive voltage to it is nearly impossible. Chances are, unless someone's been yanking on the wiring and a connector is loose, you've got a bad board, one or more of the 4 pulse lines to that motor not working. My experience suggests the most likely culprit is the engine board.

Replaced board new firmware and still stalls front pwb?

could the fuser be stalling just long enough so the page doesn't exit in the allotted milliseconds?

I can confirm that you can make a color developing motor spin more slowly, weaken, and occasionally stall ... if a person were to accidentally ... oh, say, pinch a single wire in the harness that leads to that motor ... to frame ground ... on a Copystar CS-500ci.

Don't ask me how I know. =^..^=

musta followed up on a prob from a newbie ....


yup yup yup that's the explanation!!

Or make a transfer belt on a 300Ci rotate at random times. Even at idle.

No when in maintenance mode I run the motor and stick a piece of paper in and it immediately stops.
