AN unknown problem with Ricoh af. 650

[Alebrije]

I turn on the switch.
what happens is:
- the scanner doesn´t search its HP.
- The lamp doesn´t light on. I´ve changed it.
- The display panel remains dead. I,ve changed it.
only sounds a beep and appears the malfunction symbol.
- I´ve checked the fuses (FU108) and it´s OK.

What else can i do? Thank you for your help.

I would change the PS.

[Alebrije]

Thank you Unisys12. I don´t know if that solution work, yet.

Thank you Unisys12. I don´t know if that solution work, yet.

G'day
Sounds like you've lost 24v in your PSU, run your meter along your fuses live and there should be 24v every where or unplug your outputs and test there for 24v, I'bet a can on it.

cheers

You say the malfunction symbol comes up. Is there a code with it?
I tend to agree with CEMT in that it sounds like the PSU if all the fuses are OK - there are 16 of them.

I had a similar problem recently, most likely the PSU.
First disconnect all options, and pull out all drawers to make sure you aren"t getting a short, if still a dead copier, replace PSU.

check your harness... connectors.... check your PS if reading are normal. verify BICU if its has feedback.

try replacing it...

[Anders Nilsson]

I agree with all the other and would replace the PSU
