[mindhunter]

hi everybody
My Copier Print and Scan fine . and my touch panel works too. I can select anything on touch panel menus. but my panels button doesnt work(Exept power button and contrast volume).
I try to do trouble reset too. but when i hold utility button and power on the copier nothing happens and copier doesnt go to the trouble reset page and copier start normally.
Any suggestion that what I have to do ?

First step is to dismantle the panel and check all the connections.

NO im sure the button is not stuck down . I press all of them one bye one . and as you know if a button suck down we must hear at least one beep for it . right?

Re: KM C451 Panel Problem

I have had a similar problem with bhC451 where touch panel and keypad buttons were all unresponsive. I have found after quite a bit of swap testing that the RAM cards where faulty. Changed them and all is good again! Hope this is of some help!

Re: KM C451 Panel Problem

no parts are available inside the panel. if its defective it should be replaced as a whole.

If you feel like opening it up and troubleshooting the board, that's your business but it not recommended nor suggested by konica minolta.
