3 Remove the controller board.
Use the instructions in the “Removing the Controller Board” section,
earlier in this chapter.
1 Turn off the printer, and then disconnect the power cord and all
interface cables (parallel, serial, Ethernet, and SCSI) from the
printer.
2 Remove the two screws
from the optional I/O inter-
face on the controller board.
»Note:
Save these screws.
(You’ll use them when you
reinstall the board.)
4 Unlock the standoff by
pressing in on its tip, using
two fingers, until the board
can easily be removed.
