Are the LA210 printer schematics/tech info available anywhere?
I have hardcopy buried somewhere I think. No B size scanner though.
I have one that will print a few lines, then go through
some kind
of reset (printing, lights go off, come back on, loss of text, repeat)
Self-test print fails after a few lines in like manner. Prints a few
lines, resets, and stops printing.
You likely have a bad PS. Especially if it does it during self test.
Easiest starting point is to check operating voltages. If during
printing they drop or go flakey it's the PS. The fact that it
prints at all says most of the logic is solid and working.

So I can know what voltage levels should be where, and if I find
a flakey line, which parts produce it. The power supply is a
largish block with several wires, and iirc there is a "Power Ok"
buried in it somewhere.
