I've got one of these installed in a medical clinic, where it's getting a good workout. Problem is, the staff are ready to dump it because it's C*O*N*S*T*A*N*T*L*Y cleaning itself.
It's like a cat on acid!
It's holding up production, big time. I've updated the firmware, made changes referred to in other posts here, but there's GOT to be a way to keep it from doing this, or doing it during business hours.
If I can't fix it, it's going "to a farm upstate". (I see HP's upped the rebate on demos of this unit...wonder why they might be having problems selling them.....)
