qss-37 Paper has jammed in the Exposure Advance Unit. 06209-00001 /QSS-3704

[Reynaldo]

Hello everyone, I hope you're all doing well.

A few days ago, I encountered error code 06209-00001 and I'd like to share my experience, but I'm still unsure of the root cause. The problem is a failure of the PM9 motor in the Exposure Advance Unit. The motor is completely burned out, but the rest of the unit functions correctly.

In manual mode, when I activate the motor, it doesn't turn, and there's a burning smell coming from the motor's internal circuit board.

In short, could you help me identify which board or power supply might be causing this motor to burn out?

As a countermeasure, I replaced the 24V-10A power supply, the J391483 board, and the PM9 motor.

However, this problem started five months ago, and I don't understand what's causing it.

I'll be following your experiences in case you've encountered something similar.

Have a nice day, greetings.

Respected Sir 

 

00001 The exposure start sensor does not turn LIGHT even though the paper was exposed and fed for a specified time..

1  Check that the exposure start sensor is not soiled. 2 Check that the paper sensor 1 is not soiled. 3 Confirm that the pressure guide of the exposure advance unit is correctly attached. 4 Perform Paper Sensor LED Light Intensity Adjustment of Functions via Paper Sensor Adjustment. ☞36000 5 Check that the adjustment explained in Adjusting the position of guides in the paper supply unit has been normally performed.

Thanks

So you changed motor, i\o pcb1 and ps1 and and you still get error or what?

As you've replaced the motor, the driver board and the power supply, the only other thing that I can think of is damage to the wiring loom. You will need to trace the wiring from the motor back to the circuit board. Check no cables have been trapped under a screw for example.

The only other possibility I can think of, (though it's unlikely) is the Printer control PCB is sending the signal to overdrive the motor when the printer is not printing.

Hola a todos, muchas gracias. En resumen, todo el sistema funciona correctamente; mi problema es que el motor PM9 se sigue quemando. Incluso después de reemplazarlo, vuelve a fallar. Lo que tengo que hacer es reemplazar la fuente de alimentación y la placa de circuito, y eso debería permitirme trabajar un par de meses, según mis cálculos. Lo extraño es que cuando abro una puerta, no se corta la alimentación inmediatamente. Lo noto cuando levanto la Unidad de Avance de Papel 2. No sé si está relacionado.

Voy a reemplazar el cableado como sugirió Dave y buscaré un posible cortocircuito.

Gracias por su tiempo. Le mantendré informado.

Hi, use english, please. It's hard to rely on google translator.  So from your last post I understood that you haven't changed printer io pcb 1 yet, correct? If so - you cant do it. Interlock switches' relays that cut off power with open doors are also there. But first I'd do what Dave said, look for melt wires from io pcb to pm9, check wires resistance (compare with adjacent wires), check pins condition, also check the exhaust fan in the printer control box where printer io pcb and ps1 is located (it might not be the cause, but it'll help ps1 to last longer) and vacuum clean the box thoroughly.

Hope you'll fix it and please inform on the progress.
