RAP 7.49 Memory Mismatch

PROBLEM
The amount of memory listed on the Config Sheet does not match the actual memory in the printer.
1 Disconnect the AC power and remove all SIMMS/DIMMS from the System Controller PWB and
place on a flat, non-conductive surface. The board is free from obvious damage.

Replace the System Controller PWB (REP 4.10.7).
2 Inspect the SIMMS/DIMMS removed in step 1 for obvious damage. The SIMMS/DIMMS are free
from obvious damage.
Y N

Replace defective SIMM/DIMM(s) (PL 11.3).
3 Reinstall the System Controller PWB. Connect AC Power and switch the printer power on. Print a
Configuration Sheet (5.5.2.2.1) for Version 1.7X and below or (5.6.2.2.1) for Version 1.8X, or
(5.7.2.12.1) for Version 2.0. The amount of memory listed on the Config Sheet is Base Memory.

Replace the System Controller PWB (REP 4.10.7).
4 Switch the AC power off, remove the System Controller PWB, and install one SIMM/DIMM into
slot 1. Reinstall the System Controller PWB, switch the printer power on, and print a
Configuration Sheet. The amount of memory listed on the Configuration Sheet is Base Memory
plus the value of the SIMM/DIMM.

Go to step 16.
5 Switch the AC power off, remove the System Controller PWB, and move the SIMM/DIMM from
slot 1 to slot 2. Reinstall the System Controller PWB, switch the printer power on, and print a
Configuration Sheet. The amount of memory listed on the Configuration Sheet is Base Memory
plus the value of the SIMM/DIMM.
Y N

Replace the System Controller PWB (REP 4.10.7).
6 Repeat step 5 until all slots on the System Controller PWB have been tested. Then proceed to
step 7.
7 The printer contains additional SIMM/DIMM(s).
Y N

The System Controller PWB and installed SIMM/DIMM appear to be functioning properly.
Problem solved.
8 Switch the AC power off, remove the System Controller PWB. Move the SIMM from last slot to
slot 1. Install one additional SIMM into slot 2. Reinstall the System Controller PWB, switch the
printer power on, and print a Configuration Sheet. The amount of memory listed on the
Configuration Sheet is Base Memory plus the value of the two SIMM/DIMM(s).
Y N
