I have a ImageProGraph pro-1000 that needs a new print head.   I have found a used print head online and wonder if the print heads are interchangeable ?    thank you
Does the Pro-1000 keep track of how many copies printed  ?    I have been told it does but cannot find anything on the printer menu.    thank you
The printer wont turn on.   I press the button and nothing happens.   I have electric power to the printer.  Anything else plugged into the outlet works.   Anyone had this happen before ?  thank you
the screen on my imagePROGRAF PRO-1000 says the joint lever is not closed completely.   sure looks like it is to me.   does anyone have any suggestions ?   thank you
