This is a sad story about a printer that was designed to fail.
I am not talking about the ink measuring system which will
force you to replace a brand new original full cartridge with
another fresh one just because the printer thinks it is empty,
although that is one of its features.
And I am not talking about a hidden counter which will stop the
printer dead when the secretive number reaches 44436. No, this
printer died at a very young age, with that counter at 4943,
with 90% of its life not lived.
We are talking about a problematic Epson Stylus Colour C82.
It was given to me, as beyond repair and they were right. I
have a reputation as a fixer, so I got the odd jobs and repairs
nobody else would touch with a barge pole. Just like this one.
Seldom used, guarantee expired, service doesn't want to know.
Plenty of ink but it prints blanks. Not a dot. But no errors
either. A head cleaning job, was my immediate conclusion. So we
started cleaning. And cleaning. On the third one the ink lamp
lights up. Out of black, it said. But plenty of ink inside, the
cartridge is heavy and you can hear it sloshing inside. So we
got a new one but it was getting obvious the problem lies
somewhere else as the ink pump was pumping something away, and
the ink levels were dropping.
Following excellent manual I dismantled the beast some more and
took the head out. It was soaked in ink as you would expect. So
I wiped it clean again and again but the cyan just wouldn't
stop leaking out of the seams. I put on my second pair of
glasses and realised the ink is actually leaking between the
electronic board and a seal. That is bad, said I. Not wanting
to kink the ribbons (flat electric cabling) I pulled them out
and immediately noticed a black burned corner where larger
ribbon entered the connector. A short. Nice. It was obvious.
But I had to see it with my own two eyes. The head is held
together with two slim long screws that are screwed directly
into the plastic body. The head is a sandwich of a plastic body
in two halves, a 2 large rubber seals (1.5" square or 10 cm
square each), a print board, and a piezo head that is
permanently fixed to the board. The interesting bit is how the
ink path is designed to cross from one side of the housing
through the rubber seal through the electronic board through
another seal through second half of housing and into the piezo
element. And all that was holding it together and making those
enormous seals hold the ink contained were two very slim screws
tightened into a bit of plastic. And of course the seals
failed. And of course water-based ink (cyan) leaked all over
sensitive and very dense electronic board. And there was a
short. And there was a power surge that burned a corner of
connector away and probably melted head drivers (another piece
of electronic board mounted elsewhere) away as well.
Well done Epson!! Only an idiot would design a device that
conducts water through the middle of electronic circuits in
such a fashion that it must leak. What caused it? Vibration or
temperature expansion movement were probably the immediate
cause but it was designed to leak and cause a multiple
catastrophic failure.
I say, with a great sadness, stay away from Epson. I am sure
there is a large number of happy customers but I wouldn't like
their engineers to design the brakes of my car, or plumbing in
my bathroom or for that matter anything else for me.
My two cents.
Latest update:
The same printhead is used in CX5200 and CX5400. New head is
£90.
You can buy a new printer for less.
