Mp 4500 touch screen

[Tebow83]

Hi guys,

having a problem with an mp4500 touch screen, its not responding at all, although the number keys and other ones on the control panel all work.

We swapped the control panel with a working one and the same problem. And the original broken panel does not work on the other machine.

Anybody any ideas?? Any help greatly appreciated.

Cheers

Did you swap the whole op panel unit (Plastic frame, blue buttons) or just the touchscreen?

[Tebow83]

yeah swapped the whole op panel. The one i swapped it with was working and since it was swapped the touch screen is not working. So now the machine has blown two touch screens.

The one you swapped will be just as old as the original - you need to fit the modified touch panel

the one i swapped was old but it was working before it was swapped. What was the modification made?

[TonerMunkeh]

The glue in several batches of touch screens was defective leading to a huge occurence of panels just randomly dying. The one you need is H310 9900 if it's an MP4500, if it's an MPC4500 (just checking) it's B223 9900.

Calibration of Ricoh MP 4500 BW Touch screen problems

We have an MP 4500 in the field, do we need to replace the touch screen entirely, or just contacts? This is the problem with Touch Screen Calibration.

Thanks
