T790 waiting to print - HEWLETT-PACKARD T790 InkJet Plotter Printer

Change font.

This is a service station error. One of the more common causes I have come across is a piece of paper or foreign object jammed in the service station. It is located on the right hand side of the carriage. Unplug the plotter. Plug it in and the minute that you hear the print head move, unplug the power. Then open the window, move the head out of the way and look for a foreign object stuck in the service station.
