The previous intercourse seems to suggest that you have combination of two
problems; the waste tube clog followed by a head clog (perhaps just outside,
and possibly inside as well. Now that you have the tube cleared out you may
get relief by first clearing the head clog. Read Art's manual. It covers the
dye base ink used by the C82. Additionally what you want to do is to wet
down the docking sponge area where the head sits. When the printer is turned
off the head is locked over the docking sponge and can't be moved by hand.
Turn on the printer. The head will move to the left. When it does pull the
plug out of the wall and you will be able to manually move it further left.
The docking sponge can be wetted down with "original formula" Windex or a
solution of isopropyl alcohol and ammonia in a mixture of 90/10. Use up to
10 -20 drops of the solution to wet down the sponge, then replug the printer
to the wall outlet. After a couple of hours of the head sitting over the
sponge try another cleaning and try printing a nozzle check. The problem may
be cleared up and you don't have to start thinking of clearing an internal
head clog. If not the second thing to do is to get this solution into the
print head.
The safest method is to make up cleaning cartridges (or purchase empty
ones -ie
http://www.inksupply.com/epsoncarts_xx.cfm) and then fill them
with the solution yourself. One of the problems that arises is the
chip/software difficulty when running the printer. If you get a solid red
light for any of the cartridges then printing or running head cleans becomes
disallowed. For that reason it's nice to have a chip resetter so one can
keep going and use the cartridge over that really has ink in it, but Epson
keeps saying has been used up because you've alread run through so many head
cleanings.
After I've made up cartridges what I have done is to take a syringe
without its needle, and place it tightly over each color's spike and
withdraw ink from the head, then quickly place the cleaning cartridge into
its chamber. That way the vacuum effect has the additional advantage of
drawing the fluid in. Although one could press the fluid into the head using
the syringe I would not recommend it, simply because too much pressure could
blow the print head out. Once the fluid is going in give it a couple of
hours before trying the cleaning cycles again. I've found that eventually
the C82 will clear itself using the cleaning solution.
