Bob,

That is one of the major design differences between Epson and HP.  HP puts
the entire print head in the cartridge.  It makes the cartridge more
expensive, but cleaning/repairing are much cheaper.

I have cleared gummed up HP cartridges by soaking the head in alcohol for a
minute or so.   You might be able to clean your jets with a Q-tip and
alcohol.  Be you risk leaving lint/fuzz.  An electronics supply house should
have lintless cleaning swabs.

> I have an Epson Stylus 500 inkjet that sat unused a few months with
cartridges that were already pretty old. Now it won't print yellow, altho
the cartridge seems to have wet ink in it. I tried a number of cleaning
cycles and printed a number of pages of text in yellow, to no avail. If I'm
correct that the ink has gummed up between the cartridge mount and the jets,
is there a way to clean it out? I'm reasonably good mechanically but not at
fine eye/hand stuff.
