im sure this has probbaly been asked before

i searched but came up with nothing


why does blowing on cartrages always make them work

- ive tried using alcohol - that dosent work

i thought mabey that blowing on the carts heated up the traces just a bit - so i tried rubbing the traces with soft cloth - and heat - this also didnt work

-- im afraid blowing on the carts will cause them to build up oxidation fromt he moisture in the breath

my carts are very clean and i dont see a reason why they shouldnt work with out blowing on them

mabey someone here will enlighten me as to why blowing on the carts works-
please?
