Methylated spirits? I had to look that one up. Denatured Alcohol, 95% ethanol + 5% methanol (some sites list it as 90% ethanol, 10% methanol). That might actually be making it worse later, because you're removing all the lubrication. A light spray lubricant with a solvent content might be a better choice. WD40 was the product of choice in the old days. Using alcohol, or acetone, you're flushing out the old crud, but you're not leaving any lubrication behind -- and those heads need lubrication. |
machinery. A better method might be to clean it with denatured alcohol
and relubricate it with sewing machine oil.

I only print once every 3 months; and then I find that the pins are stuck. Usually they all come out and strike after a few pages. Previously I've found that if Iput some absorbant-paper soaked in metholated-spirits on the head at the pins, it helps to free-up the pins faster. |
found squirting a little WD-40 on the print head would usually free up
the stuck pins.

As I understand it, WD40 functions mostly as a solvent - very little lubricating value. I'd think the best procedure would be to clean thoroughly and then lubricate with a light oil like sewing machine oil. |
useful in this application. The ink already has a lubricant so once the
pin is freed, printing (with a decent ribbon) will relubricate the pin.

else, particularly a solvent; its claim to fame is as a penetrating
lubricant (though there are better penetrating oils on the market --
but none so easy to find!)

better choice. Let it have a good soak to really penetrate the pin
channels. On the final soak, disolve a little 3-in-1 oil in it to leave a
light film of lubrication behind, but if the printer is not regularly used,
this can make the problem worse as the oil absorbs the ink.
