MP9000 Printer feature disabled

[mrwho]

Good morning, fellas! Here's one to mess with your brain (it did with mine):

Got an old (of course) MP9000 that started with a SC220, which was solved by replacing the LD unit.

Now everything's fine except for the Printer feature that is not recognized.

When I press the Printer button, it double-beeps.

If I format the HDD and then reboot the machine, it gives me a red Printer button and SC997 on the printer screen.

If I reboot again, it double-beeps once more.

Formatted both HDDs on a Windows PC and placed them back, without success. Also cleaned RAMs and double-checked boards connections.

Scanner function gives no problems.

Do I have a bad Scanner/Printer SD card? Or could it be something else?

Thanks!

The device usually have 2 DIMMs 256MB and a 128MB. I just dunno which of which is assigned to Printer and scanner.
It could be that 1 of the DIMMs is faulty causing it to give sC997

Could also be someone's enabled the application invalidation for the printer function as if it has a Fiery. 997 is an application selection error.
