Touchscreen cable

[tinfox]

I was taking apart on old C2500 touchscreen to put on a mp 5500 ( I think they're the same) The cable fell to the floor. How is this thing even attached?

Yeah I did, I was just curious. Do you think it was electrical glue or something? It's no wonder they all fell apart.

when i worked for the big red R, they did a swap of a ton of touch screens, not sure if it was the glue or something else was causing issues. i know some were flaky, could have been the cable becoming unglued.

Yes. According to the bulletin that Ricoh issued when these started crapping out, it was because the adhesive used to secure the ribbon cable to the screen was failing. I read a post a while back where one guy used a heat gun to reattach it. I would just get a new one.

Will a c4000 touchscreen fit the mp5000?

There are some models that use the same touch panel glass. Have a look if the ribbon cable is the same. If it is, you have a winner. On some models they move the location of the cable around so that it won't fit another model.

Check for that as well.

A conductive adhesive is used. If the adhesive is bright yellow it's in good shape. When it starts to turn brown you can anticipate losing connections. I know someone who has repaired some of these, and it's an iffy proposition. You have to have the right adhesive. You have to apply a high amount of pressure and heat. And you have to avoid breaking the glass. All the temperature changes and pressure makes the glass want to break.

Just spend the money for the new one. =^..^=
