Apple 12/600PS manual Problem with internal random-access memory RAM

Problem with internal random-access memory (RAM)

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.

If you have just installed additional RAM, open the printer and make sure the SIMMs are fully seated in the correct sockets that match one of the supported configurations listed in Chapter 5 (and in Appendix A). Try reinstalling the SIMMs, following the instructions in Chapter 5.

If this does not resolve the problem, contact an Apple-authorized service provider.
