The "!" is the "Attention light" - you are correct, this error state prevents normal print / copy function.


Known Solutions here:  Blinking Lights

See Section   Issue: The Attention light is blinking


More than just the Attention light blinking?

See Section(s):

Issue: The Attention light and the Media Error indicators are blinking

Issue: The Attention light and both ink cartridge lights are blinking
