Memory Reset/Summit
The following procedure pertains to the "Blue Logic Board" for the Summit with ROM
version 2.30 or earlier installed.
Sometimes, clearing the memory of the Summit will solve many problems totally
unrelated to the memory. The following procedure will reset the plotter to factory
defaults and will dump anything that might be causing the plotter to act differently
than expected.
1. Turn off power and remove power and data cables from Summit.
2. Remove the main board access panel located on the bottom right of the machine.
3. On the main logic board, locate JP2 jumper positioned at the lower left corner of
the board, which is marked CLR/RUN.
4. Move the jumper to the "CLR" side to clear the memory.
5. Reposition the jumper back to the "RUN" side.
The memory of the plotter is now reset to factory defaults.
