The TSB explained that there was a problem with the connector.

[TonerMunkeh]

There's been a fault with touch screens on a few models. I've mainly seen them either way out of alignment or fail altogether. Mostly Adonis C4's too.

[Dave Ireland]

Many models of Ricoh touchscreens have a defect-Ricoh is sending out replacements,list of models,& instructions.

Well on the Tessa tier 2 knowledge base

it says the cause is

The adhesive that binds electrodes to the touch panel surface contains a polymer that tends to expand under normal office environmental conditions.

Lists a whole load of models with serial cut out with the possible defect.

It's amazing that they are all failing at the same time. I can't get the screens fast enough to keep up.

We are lucky in Texas. Only had maybe 3-4 fail so far.

Here the same problem!
most on af3224c....

We were shipped enough of these to cover our population and the techs are replacing them as they do regular service calls or if they fail before that of course. We got 6 boxes of them for the different models.

The sub manufacturer is probably taking it in the shorts for this issue.

do you know what I think?

It's like other products they taking back (cars, toys,...)
not because of a little mistake,....

but when they do this it's all because off safty reasons!!!!


why should we do all touch screens preventifly now and not the only ones who are realy defective (1/100)?


who agrees?

[blackcat4866]

Can't speak to Ricoh, but...

Kyocera has had a few batches of bad displays. The official explanation is that the conductive adhesive that adheres the ribbon cable to the face develops resistance/loses connection. It wouldn't surprise me if they used the same supplier of touch displays as Ricoh. =^..^=

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?

[zyqwiz]

We had a couple when it was hot the other month. Luckily an English summer only lasts a week.

Here in Holland we had a lot of 424's that stoped working or had wrong location of the fields, callibration helped for only one week.

Annoying to have to do and of course can course a lot of problems if you go in for a paperjam and start fiddling with the op pannels many will be like
But as the replacments i belive for ricoh europe cost 1 cent at present and prevention is better than fighting fires in the majority of cases. Its probably for the best.

The problem in the UK did seem to go though the roof as other Brits mentioned in the "summer" all one week of it

So during the busy period for many copier companies ie after the summer break sept/oct if its fairly warm as sometimes happens or the heating is switched on automatically or to test for the winter as many workplaces do i have noticed causing one off freakish issues. I guess there will be another big wave of my touchscreen doesn't work calls.
