CP900 fails to boot (shows Canon screen but never progresses)

[dogldogl]

Even after disconnecting power for 24hrs, when powering on my CP900 shows the Canon screen but never progresses past that state. Is there a way to hard-factory-reset at power-on ?

Any other ideas or solutions to revive it?

I have/had the same problem. Called support to no avail. They offered a small discount on a newer model. I have built a few computers in my lifetime. The problem is that the printer was not used for a long time. There must be a battery or a diode on the control board. I had my plugged in for over 24 hours and then I did the reset procedure. That is unplug the printer and press the power button 5 times, wait a few minutes and then plug it back in and power it on. Just doing the reset procedure sometimes works, but if it does not as I said, leave it plugged in for a long time.
