chip sets are installed properly and are functioning correctly.

Turn on the printer power and watch the display for the
following:
All the indicator lights on the control panel light briefly.
Themessage RAM Check appears.
Make sure that the amount of RAM displayed by the RAM
check status message matches the new total RAM memory
(including the resident memory of 0.5MB for the
ActionLaser 1000 and 1.0MB for the ActionLaser 1500). Use
the tables in “Selecting a memory chip set combination”
described earlier in this chapter.
If the correct amount of RAM does not appear, turn off the
printer and remove the controller board to check that the chip
set is in the correct sector and that each chip is well-seated in its
socket. If the RAM check message is still incorrect, contact a
qualified service person for assistance.
