Canon Imagerunner 6255 control panel not working

[Crazy Monkey]

I have an old (> 10 years) Canon Imagerunner 6255 that came off an old lease. I have kept it going for the last 5 years. In the last year, the touch screen became flaky. At first it takes multiple tries to hit a "button", but I can still use it. Now, the touch screen is almost totally non-responsive. All of the physical buttons are not working either except for the Power/Sleep button. I have took the control panel apart and cleaned the touch screen edges. I disconnected the touch screen connector to see if I can get the physical buttons to work without success. The machine starts fine with no errors showing. The LED lights on CPU board 1 and 2 are lit. I can still use the machine as a printer. Without the use of the physical keys, I am dead in the water. There is a mention of faulty CPU board related to the clock signal. Here are some of my questions.

- Is this related to the CPU board under the control panel or the main CPU board? I don't want to spend much on this old work horse. My current control panel board version is FM4-9880.

- Can I just update the firmware to correct this issue? Is the new firmware compatible with the old boards. Can firmware be updated without the use of the control panel?

- Can the batteries on the main CPU board 1 and 2 be related to this issue? I am sure the old button batteries on those boards are long gone by now.

Thanks for all of the help and I will buy people coffee once the issue is resolved.

Why don’t you replace the whole control panel? It sounds like the touch screen has been on its way out and maybe now the cpu In the panel has gone bad.

On a keep it simple note, make sure none of the buttons are stuck down.

I took the control panel apart and make sure no button is stuck. It will cost ~$300 to get a used control panel with no guarantee. This machine is more that 10 years old, I don't want to sink too much in it. I am hoping to find a replacement/upgrade CPU board for the control panel for less. Anyone with a used FM1-U976, please let me know.

CPU may not help the touch screen. That may need the touch screen glass

Can anyone tell me how to get the latest firmware (USB version) for the copier? Will the new firmware work with the original control board (FM4-9880)?

I got Firmware of this model. Do you need?

[Crazy Monkey]

Thanks Nick. I do need the firmware for 6255. Thanks.

Thanks for all of the help. I got an old FM1-U976 control board. This is the board right under the buttons. I swapped out the board and the touch screen is working again. I am not going to update the firmware. Project finished.
