Hard Reset – While printer is powered ON, pull
the power cord from the printer then from the
wall. After 30 seconds reconnect power to
wall and printer. This will trigger a ‘dirty power
up’ and restore the printer to a known good
condition (if it is possible). No user settings
are lost with a ‘hard reset’.
This ‘Hard Reset’ is one of the most powerful
tools to use when the printer hardware is not
if in warranty,contact HP tech support. what is your printer model?

I have the same problem and tried unplugging and replugging. I still get the "possible paper jam" message. A near expert in printers from Cartridge World tried everything: Replaced old belt and belt tensioner, checked all of the paper path sensors for damage and operation, checked and cleaned the encoder strip, cleaned and re-lubricated carriage rail replaced scan-axis motor, replaced line sensor, cleaned service station and replaced carriage bushing. He seems to think the next step would be a carriage assembly replacement and formatter replacement. Could be costly if this isn't the problem. He's already invested $200.00.
I haven't owned the HP DesignJet Z2100 long enough to replace a large format circuit board.
Please advise, the printer is too costly to just give up on it.

I am sorry, but to get your issue more exposure I would suggest posting it in the commercial forums since this is a commercial product. You can do this at: http://h30499.www3.hp.com/t5/Printing-and-Digital-
I hope this helps!
