7.2 PROBLEMS
Plotter does not plot
Possible causes: Plotter has no paper or film
Lid is not securely closed
Thermal printhead is overheated
Latch pins need adjustment
Solutions:
1. Check the media supply. Install more media if necessary as
described in Chapter 3, Installation.
2. Check that the media is installed correctly and the plotter lid is
securely closed. The top of the lid should be flush with the top of
the side panels.
3. If plotting has stopped in mid-task, the printhead may be
overheated.
Do not intervene. The plotter will resume plotting from where it left
off with no loss of data when the printhead has cooled sufficiently.
When the printhead temperature reaches 60ºC, the plotter stops
and asserts a “busy” signal to the host. Plotting resumes when the
head temperature has cooled to 45ºC. This prevents printhead
damage caused by overheating.
4. If the lid does not close securely, or if the head pressure is too
low, contact your authorized service center.
