Required
Action
Use the correct
emulation software
option(s) for this
model. If the printer
is an IBM
6404–B01, the
controller is a CBO
board. If the printer
is an IBM 6400, the
controller is a CMX
board.
There is no program
in printer memory.
Go to step 2.
Check the security
PAL at location U54
on the CMX
controller. If the PAL
is absent, install the
correct PAL. If
security PAL is
present, replace the
CMX controller
board.
Replace DRAM. If
message occurs
with new DRAM,
replace CMX
controller board.
Download the
program again:
Power off the printer
and start over at
step 13. If the
message occurs
again, replace the
flash memory.
Download the
