Rejuvenating antique printer - Toner dump? [View all]

No matter what I have done to my Panasonic, 1994 vintage, spots/spider bites remain. I get a faint dark area that divides the page into thirds too - horizontally. The spots are always the same. No change with cleaning. I've tried 70% rubbing alcohol, soft cloths, cotton, vacuum.

The Drum and Toner/developer units were replaced at one point, years ago but they've not had that much use. And that replacement didn't help much.

I'm thinking now there must be dust in the small transistor boards inside the printer, or the contact for the power cord jack/assembly. Or the toner. The cartridges are not new, they're old stock because not manucfactured anymore.

So I'm considering radical innovative exploratory cleaning. Turning the developer upside down to force the toner into the reservoir, then cleaning out the gearing, roller, magnetic rod. I'm fairly sure the toner has some lumps in it. But they just can't be that consistent in making the same spots all the time.

Anyone with experience in these areas? Thanks in advance if you can weigh in.
