Removing the Bottom Cover for Internal Access
WARNING
•The 300 system cutter is very heavy and could cause an injury if it falls. Make
sure that another person assists with moving the cutter.
•When the bottom cover of the 300 is removed and the power is on there is an
electric shock hazard. These diagnostic procedures should only be performed by
qualified technical personnel or individuals that are aware of safe practices with
110 VAC and 220 VAC devices.
Do not lift the 300 by its top dust cover, or the tray assembly. Use the
bottom surfaces of the end plates for lifting and moving the plotter.
Tools Required:
•Phillips head screw driver.
•Two people capable of lifting 50 pounds each.
•Grounding strap (optional).
Perform the Following Disassembly:
1. Turn the power off, and disconnect the computer data, and power cables.
2. Move the carriage assembly to the right side of the cutter.
3. Remove the right side cover. See Removing the covers earlier in this procedure.
4. Use your assistant to help you flip the 300 cutter over onto it’s top dust cover. Use
the right side cover to place under the tray so it doesn’t fall over while it’s on it’s top.
See figure 4.
5. Remove the phillips screws along the bottom cover’s edge. See figure 5.
6. While removing the bottom cover, take care in unplugging the fan wire from the logic

allassemblyreplacement procedures.
1. Shut off the plotter and remove the power and computer data cable.
2. Perform the procedures in Removing the Bottom Cover for Internal Access above.
3. Mark all of the main logic board connectors with a felt tip pen before disconnecting
them. This will make it easier to correctly install the connectors after inserting the
new logic board.
4. Discharge any static electricity that has accumulated and remove all of the plugs
and connections on the logic board. Use the Interconnect Diagram in the Appen-
dix section as a location guide.
5. Remove the logic board by loosening the four phillips head screws and pulling the
unit out of the track in the platen.
6. Replace the new logic board making sure to insert the top edge into the support
track in the platen. Insert and tighten the four phillips screws from above. The
fasteners only need to be snug and can damage the logic board if over tightened.
7. Connect all of the plugs on the logic board. Use the Interconnect Diagram in the
Appendix section of the 300 Service Manual and the notes from step 4 as a guide.
8. Plug the power cord into the 300 and into a wall outlet. Power the machine on
using the reseting procedure below.Test all of the functions of the keypad.
9. Reconnect the serial cable and perform test plots. Reassemble the 300 in the re-
verse order that it was disassembled. See General Disassembly Procedures erlier
in the procedure.
