I'd have to be sure it was worth the extra bother. In what ways are
the Canons more reliable? Thanks.
The Epson r2x0/r3x0 series depends on an ink waste station for proper
operation. It's a little system that has a pad, a rubber wiper, and is
on a sort of plastic dowel and grove system that causes when forced to
the far end by the head rises up to make contact with the head. The
head, when not in use, sits on a white gasket which is only connected
to the waste station by a hook on one side. If for example this waste
station were to get knocked out of place, the head would be exposed to
air and will clog, this device with a rubber wiper that smacks against
the head every stroke, and this pad which is hend on by nothing more
than a hook, this pad which will get ink soiled, has to be ink soiled
to make a proper seal. On top of this, the main head shaft rises to
accomidate thick media such as the CD tray which is there and abouts of
0.1 inches high. This waste station is mobile and does lock into place
via a lever which will fall back into place when the head smacks into
the arm. On top of this, the r200 at the very least has no frame what
so ever. The thing is assembled on a jig, and is held together simply
by the plastic shell.
The Canon is using a thermal printhead. They do have a limited life,
officaly I think it's limit is about 10 cartridge changes but most
users say "20" cartridge changes before they consider another head.
Thermal is a more simple system than micropiezo, it uses no moving
parts, has a shorter nozzle length, and any clog that might happen is
likely to be cleared by the action of cleaning as the force of steam is
rather powerful, vs something that depends in part to gravity to drop.
Now i'd lean tward micropiezo in terms of life, these things typicaly
don't have to be replaced. The problem is a clog is a much more
serious matter and in fact the cleaning cycle is nothing less than a
hydro pump.
I'm not saying the canon doesn't waste ink, it sure does. If you don't
use the printer for 96 to 120 hours, it will auto clean using .14g of
black, 1/2 a gram of color. If you don't use your printer for more
than 1 year hours it will use 1.5g of black, and 1gram of color. This
info is in the ip4000 service manual, and the newer printers may be
different. I can't say how many grams the epson uses in terms of waste
ink, but having an external inktank I measured my waste ink in terms of
ounces. The canon design isn't the most efficent out there, but the
Epson is far worse.
So you asked in what way I found the Canons to be more reliable. Using
very old thermal printheads, while a disadvantage in terms of choices
in ink and prone to burn out eventually don't depend on a complex
cleaning station which is actuated by the smacking of the printhead
against it.
