Sorry to jump into the thread and I don't know which printer you have,
but my advice is never to run more than 3-4 cleaning cycles in a row.
Then turn the printer off for minimum 6 hours...or if you must try for
more cleaning cycles, run a quick purge pattern/print or two first.
But I don't recomend second method.

After three cycles or so, the ink gets sucked too quickly/much out of
the bottom of nozzle, leaving none in printhead. It then needs time
for gravity to replace the ink in head- else you get your nozzle check
disapearing more and more.

In an 1280, I found that I needed to turn printer on, run a MIS purge
pattern and nozzle check about once a week (for OEM carts) and at
least once a DAY for the old MIS ink to minimise clogs. From previous
posts (none lately though), some will remember that I live in Colorado
where it becomes very dry in winter months (down to 20% RH). I have
clogging issues even with OEM carts with 1280 and 1160. Curiously,
2200 is about 50 times better behaved. I run a good humidifier around
45% humidity, but still have some problems. I should also say I have
no experience with running the new, better UT type inks- just the old
MIS and piezoBW stuff.

Maybe, but I never personally found clogging to track level of ink in
cart in 1-2 years of keeping tabs. As long as ink was not below chip
parameters.

Epson told me about 6 months for 1280, but I don't see the saran
wrap/foil thing as being nessecary. I think I personally reused 1280
carts up to 4 months. In my 1160's, I couldn't re-use carts very well
because they didn't seal on removing-one use only, or two or three
uses with some trouble. When I put them back in it was hell. The
bottom ports of Epson 1280 carts will seal themselves- no problem,
three reuses or so roughly. For a 1200, I don't know.
