HP Ink in Epson Printer...OK??

Hi All,
I have a supply of large capacity (350 ml) HP ink carts from a wide
format printer that my company no longer has. The carts are out of date
but have never been opened. I am thinking of building a CFS system for
my new Epson R300 and I wonder if the ink from the HP carts (dye based)
can be used in the Epson printer. Epson inks are dye based also so I
have a feeling this will work. If my idea is correct all I will need to
find is a set of always full chips for my Epson carts and the time and
patience to try building the continuous flow system.
Anyone have any thoughts on this???

A few things to watch out for:

1. If the ink is beyond its expiration date it may have become thicker than
normal due to vapor loss. This may cause issues with the nozzles clogging.
2. Some inks use ph to control black to color bleed - the black ink may be
somewhat acidic, the color ink basic (or vice versa) so that when they print
black and color close together they maintain crisp edges and do not bleed
together. If the inks are not compatible with the ph of the Epson inks you
will have the reaction occur in the printheads, likely ruining them.
3. The servicing algorithms in the Epson printer will be tuned to Epson ink.
It may or may not work with different inks; you may have to do more cleaning
cycles.
4. The colors may not match correctly since the color maps in the Epson
firmware will be tuned to the Epson inks.
5. HP Black inks are typically pigment based. This may not be compatible with
the Epson printhead.

Personally I would probably not try this with a new (still under warranty)
printer - I would find a cheap old beater to experiment with....

Wow!
Thanks for the great information. You have given me a lot to consider.
Just wondering...All the bulk ink I see for sale with commercial, ready
made CFS units, is this ink specially formulated to be compatible with
the printer you are installing the system into? Or are these simply
generic dye based inks?

Thanks again for the info.
 
As you probably know not all Epson printers use dye inks, some are
designed for pigmented. However, many people have successfully run
pigmented inks through the dye ink printers, and I suppose vice versa.

However, I do believe the R300 is a dye ink printer.

Dye ink formulations are all similar, BUT, they can be different in pH,
charge, viscosity (thickness), boiling point, evaporation rate, drying
factors, size of filtering for solids, color dye used, etc.

Keep in mind that most HP printers use a thermal method of projecting
the ink to the paper. That means a resistor/heater in the head warms up
and boils the ink, and the liquid in the ink changes to vapor at the
head and projects a drop of ink forward.

Epson printers use a piezo-electric actuator which flexes when an
electrical current is applied, and this causes a droplet of the ink to
spray out the nozzle. The ink does not require any heating at all.

So, will the ink work? It may and it may not. It may just make a mess.
If may work, but run or bleed on the paper and it may require
experimentation with paper and color management to get a similar color
result to the Epson inks. It is unlikely to ruin the printer head,
unless the pH is very different and it causes clots with the Epson ink
when mixed. You may find it doesn't work very well and you have to go
back to Epson inks.

Epson inks are alkaline, and mix well with ammoniated window cleaner
which is also quite alkaline. SOme Lyson inks, made as substitute inks
for Epson printers, are acidic and cannot be mixed with the Epson inks.

You may wish to test the HP inks to see if they mix with ammoniated
window cleaner, as a check for pH.

Wow,
You folks are great. Thanks for all the terrific info. After reading
your replies, I think I'll at least stick with compatible cartridges
for safety's sake. I surely don't want to screw up my new printer and
some of the compatibles that claim to be guaranteed seem the safest way
to go for now.
