What's wrong with the touch screens?

[zyqwiz]

I ordered one and it wasn't a special low price - I paid full price for it!

How much was it then?

We only replace the touch pannel (b2239900) and the rest is payed by Ricoh Japan!

We ordered a touch panel RIGHT Before these bulletins hit that admitted the problem so of course its the old part#. Cost around $500

I was having a moan about this back in December 08 and no body in the northen hemisphere seemed to have much of a problem with it. Its the end of winter here now and the field techs arn't going through as many as they were in summer. Perhaps its heat related?

That could be possible, as we've had our two days of summer here in the UK and I had one of these go. Makes ya think......

Come to think of it now!!

I replaced all of mine in summer and had not yet replaced one this winter. hmmmmm?

Hi Guys, I had a touch screen that nothing would responded so I pulled the touch screen connetor out an saw that the foil connector was dented in so I flatten the dent and put tape backing on the mylar that was changed on the tech bulletin and guess what it works. So my thinking is that there is nothing wrong with the touch panel itself just the mylar behind the foil connector that does not support the constant pressure from contacts on the foil connector. This might save a few bucks for the ones who have to pay for the touch panel, in the USA Ricoh has a no charge replacement so it doesn't cost us anything.

I ordered up a box of B2239900 to cover ourselves - they will put the price back up at some point! My D0299900 ones are still on back order though.

Hi guys,
My MPC4500 touch screen responds only from middle to top part of it, bottom nothing. But the strange thing is that if I use some cleaning surface product over it, the same works also in the bottom part for some minutes, after stop responding.
What do you sugggest? Do I need to change it or I can do something to fix it..?

Thanks in advance,
Fabrizio

Perform a full touch screen calibration, Yellow 1993 Red x5. If it is still off, remove the operations panel, remove the back panel and boards, then careful remove the touch screen (take note of the ribbon cable, if the end is white it is a modified part, if it is brown it isn't; the brown ones are faulty) give it a clean. If it is clean and still does it, replace.

The conductive compound between the ribbon cable and the touch panel detoriates by the time. Only solution is replacement. Densi has them for a good price. The Densi # is RHPT0002
