Look, friend, I have assisted thousands of people in the repair and
unclogging of Epson printers, yes, you've read that correctly: THOUSANDS.
The results have been way over 90% success rates, and not in one case
have I even needed to recommend removal of the heads unless they were
failed and required replacement.
However, I have had to provide the sad news to dozens and dozens of
people who have removed the heads to their printers that they have
managed to destroy the heads in trying to clean them outside the printer
and that's why they "won't print anymore".
I am not saying that Epson doesn't remove the heads, or that even Epson
service depots don't remove they heads, they indeed may do so. It may
indeed be more effective to do so IF THEY KNOW EXACTLY what they are
doing, and if (and when) they do screw up, they have free replacement
heads available to them, and the setup program required to replace the
heads.
I stand by my statement that the only reason to remove the heads on a
consumer Epson printer is to literally replace the head. Otherwise, it
is not only unnecessary, but it can be potentially hazardous to the life
of the printer, because it creates many potential problems. Further, it
requires in nearly every case, that the case be removed from the
printer, which again, on many requires knowledge of the procedure to
remove the top of the case. I have seen many Epson printers with broken
cases, ruined ribbon cables, bent or distorted shielding, lost screws,
non-functional control panels, etc, as a result of someone trying to
dismantle the printer without the service manual and even some with
people who had them.
Unless you are going to start explaining step by step or supplying
service manuals to each person who you suggest "remove the head" of
their printer, I strongly suggest you stop giving out this advice which
can lead to a lot of broken printers.
I suspect you have not personally worked on many Epson printers, or you
would be more careful about offering this advice to the average person
needing to simply unclog a head on the printer (if that is even the
cause of the printer not printing).
