Epson Photo Stylus 750 printer - no black

[Dan]

I have an Epson Photo Stylus 750 printer that I can't get to print black.
I've tried the Windex in the ink snout tube trick, I've tried multiple cartridges many, many clean cycles and no black. Some black printed with the Windex but no more.
Is it possible the head is shot? If so, is this an easy fix? How expensive and where do I get one?
I'm very mechanical and confident I could take it apart and replace the head I just want to be sure first.
Is there a good test to see if it is the head?

The color does print, by the way.

Thanks.
Dan

Dont forget there is a level sensor mounted on the front of the ink
cartridge holder (small black thing with two leads out going to the rear.If
this has moved ,or is faulty it will give no black faults

Try changing out the black cartridge with a new one.
Epson's are notorious for the cartridge seals going bad.
Also might try unpluging the printer to clear the logic functions.(
Had a Epson 1500 years back that was bad about that.)
I also had an 800 that would lose cartridge seal often.(wound up
junking it after spending too much on replacement cartridges.)
You can but aftermarket seals though I've had nothing but bad luck
with that option.(Bought a pack of 16 seals for just over 20 bucks and
only got 4 or so to work. They're just nitrile rubber o-rings and what
with the cartridges made of such cheap plastic with all sorts of
irregularities in the surface of the exit ports the 0-rings woud
seldom form a good seal.)
What with the ink cartridges just being a tank with a porous sponge
internally there's seldom much that'll go wrong if they've been
properly jet-molded.(very rare to get a really good one though.)
If it's a clog problem it'll be in the print nozzles most likely.
Removing the printhead and cleaning it with a solvent.(Sulfynol is
what the Epson repair shops use.)
I've had good luck with denatured alchohol(soak it overnight for bad
clogs.) followed with a rinse in distilled water.
You could try getting a blank cartridge and loading it with cleaner
and try flushing out the head.(How the repair shops do it.)
