Was trying to find a thread where I don't hijack anyone elses problem and here we go J34


I have more and more issues with J34 and J32 all in registration. All machines have modification in feed sections a.e springs, new type rollers and separation mylars. As I have quite a few machines with this issue I decided to have in office one machine that is solely for eliminating j34 and j32.. meaning I use the reg units from failing machines in this dedicated to check if its reg. unit problem or more than that. As the dedicated machine had a overhaul, and I am confident in it, than it has to be the registration unit.

As I have not got any spare NEW reg motor or reg-feed motors my question is ..has anyone changed these yet? I hardly ever had a step motor to fail. When I wiggle the wiring it starts to jam like mad.Ocasionally I hit the right position on wiring and it works. Swapped motors registration with reg-feed where I had to turn the bracket on both motors by 90 degree. Still jamming. Is it the connectors or the actual wiring.. Has anyone had that? Already ordered one set of wires ..2 months to get it in

Just asking to check if I missed again something.

It sounds like you've got the problem nailed down. I've never changed a registration motor, but that doesn't mean anything. From what you've said, there is probably a loose wire connection in the body of the motor. Can this motor be disassembled for a better examination? =^..^=

I am on it now! Just landed my multi-meter to colleague and he wont be back today


but I am trying "different" wires from another machine...and if that wont work, then...the HARD WIRE a.e no connectors just straight solder in to the Transfer/Fuser TRAY Assembly Connector ..Bypassing any other connector issue.

Will keep you posted.

Thanks BC for prompt response.

Pulse motors as we find them in copiers have three or four magnetic circuits which are "pulsed" at very specific intervals to regulate the motor speed. For three circuits there will be six wires, and for four circuits there will be eight wires. The motors that I have examined all have approximately the same resistance across each circuit. I would attach clip leads and perform the "wiggle" test. If the resistance changes when you tug on the harness you've found the problem.

Sorry. I misread your initial post. It seems like you've isolated the problem to harness and/or connectors. The most vulnerable of these is the main drawer connector. It would help to bring along a friend to help you meter pins from the duplex PWB (connector YC5) right to the registration motor. I would think that with the imaging unit removed you could pull out the drawer, clip on leads, then close the drawer and read values.

As long as you're in there, I'd watch for rust dust from the fuser drive pack raining down on the duplex PWB.

Good Luck! =^..^=

May well be...now just someone to give me hand. Tomorrow another day. Thanks... I have tried another reg .harness(maybe faulty too) and it is going worse so have to wait for the "hopefully" original fuser/transfer/reg drawer to come back tomorrow. Only then I can say confidently is the REG or THE HARNESS from REG or the harness and connector on drawer.. doubt it would be close to PWB issue as that is hardly touched and the machine done on friday 4k without jam..so ...it must be on the drawer OR within.

Sun is shining..going home.

Just wanted to add in case someone need the motor specification in the future Shame only latest models are there Hybryd Stepping Motor Registration specification17PM-K.pdf
