7.2PROBLEMS

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.
