Thanks for your help, folks. Anyway, the printer has now completely stopped working; it just flashes its error lights. I'm going to bring it in for professional repairs. It may seem economically foolish to do so, but I'm not aware of any current low-priced printers that can print on 3x5 index...
I'm running into the problem shown in uploads at 8285_cci07052011_00000.png with my IP4200. Since I'm a new user here, the system won't let me post the link inline; this is the best I can do. Basically, there are bands about the height of a line of text in what should be solid-colored areas...
