10 Slide the controller board back into the printer.
11 Replace the two screws that hold the controller board in place.
12 Turn on the printer.
The printer does self-diagnostic tests each time it is turned on. During this
testing, the printer verifies the amount of memory installed. If the test
determines that a SIMM is faulty, specific status panel lights come on.
Try reinstalling the SIMMs, following the instructions earlier in this chapter.
If this does not resolve the problem, contact an Apple-authorized dealer. (For
more information about diagnostic tests and status lights, see Appendix G.)
