PRO 951 message "Plase close the front door"

[ysshin79]

Hello.
I am Korean.
I'm writing on a language translator, so I'm not sure if it will be delivered properly.
I'd like to ask you a question.

The warning "Please close the front door" will be displayed on both of the 951s.
And there's something in common. Both of them have severe internal dust contamination.
1 - DCPS/2 Disassembly Assembly and Illumination
1 - Exterior cover and interior simple dust cleaned and lit

I'll write down my replacement.

1 - Front door Photo Sensor 2EA
2 - Check Fusing Unit Connecter
3 - Replace ADUDB
4 - DCPS/1 and DCPS/2 Replace
5 - Check Fusing Unit Connecter on the back of the body
6 - Cleaning the ADU connection connector

If you have any experience, please ask me a favor.
Have a nice day.
Thank you.

Have you checked to see if your door switches are getting the supply voltages?

Check the finisher doors as well or disconnect and see if problem goes away

Check ICP's.


Blew a board 2 weeks ago. First in years:(. Plunged the finisher in on the wrong connector and got similar results.
Lucky its was only an ICP.

Thank you for replying to BLACKCAT4866.

I haven't checked the voltage. I'll try. Thank you.

Before I post, Bsm2, I did it without finisher.
Thank you for your reply, I'm sure you are busy.

Thank you allan for your advice.
Let me check if there is an ICP defect.


Have a nice day.
