Removal and Replacement

ELECTRONICS ENCLOSURE COVER REMOVAL

To remove the electronics enclosure cover, perform the following procedure:

1. Switch the plotter OFF and disconnect the ac power cord and interface cable from the

plotter.

2. If a modular input/output (MIO) card is installed, remove the MIO from the plotter.

3. Using a TORX T-15 screwdriver, remove the rear sideplate trim pieces and electron-

ics enclosure cover shown in Figure 6-3. The C2858A has 10 cover screws and the
C2859A has 12 cover screws. The trim pieces have two screws each.

4. Gently pull the trim pieces and then the cover off of the plotter.
