Solution
After installing
additional memory
(memory chip set or
a memory expansion
board), the printer
does not function as
expected.
After you turn on
the power, the RAM
Check message does
not display the
expected amount of
memory.
The RAM chips or the optional memory
board may not be installed correctly. Turn
off the printer and check the installation.
Make sure that the chips are installed in
the correct sector of the main board and
that each chip is firmly seated in its
socket. Also make sure that the notches on
the chips are all pointing in the correct
direction. See Appendix A for more
information.
You may not have increased memory on
the printer’s controller board before you
installed the memory expansion board. A
memory expansion board can be installed
only after you have increased the
controller board memory to the maximum
2 MB with the optional memory chip set.
See Appendix A for more information.
