I think it does, I used a 2022 in school and it had one.  Hold down the
line-feed button when you turn it on...

It's obviously an error message, but I don;t have nay blink-code references
for printers... for the 8050/8250 5 means - Zero Page - 6530, K3, 6504, H3; 
But I don't think it would match for the 4022...  :/

Only thing I can think of (as I'm not the hardware expert) is check the fuses,
I know on later printers (MPS 801) there is more than one fuse in it.
