True, but also try a new toner cartridge, just to make sure, and that is
the easiest rotating bit to replace.

But there is no toner in the case of scanning a photo.

1. I put the photo in the scanner slot
(the HP LaserJet 3200m is not a flatbed)

2. I bring up IrfanView on Windows & select
IrfanView: File Acquire/Batch Scanning

3. That scans the photo into the computer but the
result is horizontal streaks (perpendicular to the direction
of the paper flow).

The glass plate inside is about 9 or 10 inches wide and 3/4 inch tall and
I cleaned it before asking you what the problem was.

I don't see anything else inside that "sees" the photo other than
that paper-width wide strip of 3/4-inch wide glass.

The conundrum is that the streaks are in the opposite direction
as anything that touches the photo (the rollers roll in the vertical
direction but the streaks are in the horizontal direction).

That enigma should give me a clue as to what the cause is, but
I can't think of anything that goes horizontally.

This is what the HP LaserJet 3200m looks like
