I always fill my own ink cartridges for deskjet printer, my lates hp
printer requires a vacuum fill or as near as I can get to a vacuum.
Anyone solved this or any ideas.
I basically need to have the ink cartridge in a vacuum and then let the
ink flow into th cartridge probably using a syringe.
I was thinking of one of those plastic stay fresh resealable type zip
bags and somehow sucking the air out with a vacuum cleaner nozzle and
then injecting through the polythene with a syringe.
best I can come up with so far.

I basically bought the last of the Canon inkjets that does not
use chipped cartridges and the cheapest non genuine in carts
are so cheap that I don't have to fart around refilling anymore.

Can't quite see the reason for the plastic stay fresh resealable type zip
bags ?

The other obvious source of a cheap vacuum pump is those
systems used to get the air out of food plastic bags for freezing.

To avoid putting the hoover nozzle on the printhead as this would damage
it, if I can place in a bag and suck the air out then put the ink in via
syringe, this would avoid touching the print head. (I think/hope)

OK.

I still cant see how you get the ink from the bag when filled that
way, into the print head or more strictly the inkjet cartridge.

I'd personally be more inclined to try two needles into the
cartridge, sucking on one with one of those food bag vacuum
systems if there is some way to connect a needle to them, and
the other needle being where the ink is fed into the cartridge.

Might well be a problem doing that tho, its often hard enough
to just get the one needle with the ink into the cartridge.

And I've never tried dismantling one of those food bag vacuum
pumps either, so its not clear to me how easy it is to get it to suck
on a needle either.

The 2 needle system would not create enough of a vacuum, I am thinking
of those vacuum bags you can get for clothes storage whereby you connect
a hoover nozzle and it sucks all the air out and compacts the clothes
inside (ideal for travelling) that would certainly create a vacuum. So
what I require is a smaller version of this but with an ink cartridge
inside it, then all I need is a way to get the ink in without breaking
the vacuum, possibly through a felxible piece of rubber or similar.

Some Youtube videos suggest that the syringe is used as the vacuum
device. Insert ink into cartridge one one side, turn it over so the
filling side (bunged up) is at the bottom and the syringe used to draw
off the air (lock) pocket.

Other methods suggest that the ink input is a tube connected to the
replacement bottle and the method of filling is to use the syringe to
pull the ink through - and at the same time removing the air.

OK, I understand now, didn't manage to grasp that you want to
put the cartridge in the bag.

Those unsightly marks on my legs are due to me kicking myself.

Have you no sense of common decency whatever during the festive season ?

Wouldn't it work if you injected the ink first, bunged up the filling
holes, and then put the cart in the bag and evacuated it so as to
prime the cartridge by drawing ink through the print head?

Spinning the cartridge in a centrifuge with the head facing outwards
should work.
I've managed to prime ink cartridges by tying them on a plastic bag in
a suitable orientation and swinging it round above my head.

Messy things.

All the "compatible" cartridges for my Epson have all had compatible
chips. The problem is finding a good quality compatibles.

The last lot I purchased are in boxed sets of 4 (black and 3 colours) at
around �5 per box. They also have 50% more ink than in a Epson product.
Once I find something that works well I then buy a job lot from the same
seller but often when I come to reorder, say, a year later the product
has changed or the retailer is no longer in business.

The carts that came with the printer caused all sorts of issues when
refilled and thats when I discovered they require a vacuum fill.
seemingly the air at the bottom of the cart limits the ink flow.
I could ony get around 30 pages and the ink stopped flowing.
I did try several cleans and primes to no avail, I now have replacements
but they will need filling shortly.

That clearly adds to the cost of the carts.

That's not a problem with those non chipped carts.

Mine are a hell of a lot cheaper than that.

Mine are so cheap its not worth even bothering, I buy
so many for so little that there is real doubt about
whether they will still be viable for last of the carton.

No sign of any problem in years now.

Which is why dirt cheap to start with is so much better.

On Wed, 26 Dec 2012 21:11:03 +0000, ss <wee...@hotmail.com> enthralled us
all with:
I think you would get more negative air pressure by sucking air out of
the cartridge with a syringe than using a big plastic bag and a 'vacuum'
cleaner.

I think you only need to reduce the air pressure in the big plastic bags
by a very small amount for them to be compressed by atmospheric pressure
- you are probably mainly removing excess air rather than creating much
of a vacuum.

Perhaps you might be better off with a small vacuum pump and a bell jar
or demijohn where you can route your tubing through the stopper and keep
a small reduction in air pressure inside the jar which should be all you
need to remove air from the cartridge.

Mind you it is a long time since I did 'A' Level Physics when they gave
you this kind of toy to play with :-)

I am wondering, though, why they need a vacuum fill?

Presumably previous cartridges had some kind of two way breather so that
air could be vented when ink was added under pressure, and air could
enter as the ink was used up.

Speculating wildly, this might encourage evaporation and the cartridge
drying up.
So they may have introduced some kind of valve or membrane to prevent
this.

I still wonder why a vacuum, though.

If the internal pressure of the ink is higher than the outside air
pressure then air should flow out of the cartridge. Reducing the external
air pressure may speed this process but ink should still flow in and air
should still flow out as long as there is ink pressure from the syringe.

Cheers

Nor I, for food, but I do use them for some collections of DIY bits & pieces
I want to store flat but airtight.

This will get you a better vacuum than any vacuum cleaner.

Without the vacuum there can be a layer of air just above the printhead
that causes the ink to stop flowing,apparently it acts like a dam, if
vacuum filled then this air doesnt exist within the `sponge`and the ink
flows freely.

When I wrote my reply I was tried to remember what I last used them for and
couldn't. 'Airtight' was misleading though, mainly I want the bag to be
sealed so what's in it doesn't fall out.

An example: I have a set of these bags, about 10" square perhaps with
various sizes of heat-shrink tubing and expandable sleeving (for electrical
cables) in them. There's most of an A4 page of paper listing the contents
visible through the bag (and the way the bag closes entirely flat means the
paper stays flat and legible). Also the bags stand up, like a series of
cards in a card-index, so one can pick through them to find the right size
of tubing.

Yeah, wondered about that too.

I'll have to consider that for my DIY bits and pieces.

I currently mostly use post office mailing boxes I bought in bulk for
the bigger stuff like say those plastic clip together hose fittings,
batterys, all sorts of stuff. I have about 50 of them.

And glass jars with lids for other stuff like screws, pop rivets etc.

When I was building the house I used small tonic
cans, but I don't get any more of those anymore.

Just got a great swag of those plastic bins from a garage/yard sale for
peanuts.

If you go along to one of those kids sweetie shops, one that sells 1p
sweets, some of them are dished out from a good sized rectangular
plastic boxes with a flip up lid - Haribo I think. If you ask nicely,
they will give you the empty one for free and they are perfect for
storing small items. They also stack well on a shelf.

Not sure if we have any of those anymore. Only one of the
schools even has a shop close enough for the kids to use
and I don't think that the kids are allowed to use it anyway.

Yeah, they sound ideal.

I also use those rather large plastic parts tray things with the flip
up lid with the small rectangular grey plastic bins in them that
must be about 30mm cubes with one side open for stuff like
the screws and jumpers used in PCs etc and for the parts when
dissembling stuff as well. Works very well for the smallest stuff.

A Vac-u-vin stopper, or a Vac-u-vin coffee jar, will go down to about 1/4 atmosphere, which is enough for most "mechanics" processes where you're looking to generate a pressure differential. Handy for degassing epoxy or silicone resins.

That sounds like a good option for trying.

The new Compatible carts now come ready chipped for both Canon and
Epson. No need to swap chips or any of that faffing around, my Epson
carts are around 90p each.

The Epson (no-name) compatibles that I've had no problems with have come
from this Ebay seller, however past purchases are no guarantee that
future purchases will be to the same quality. I've no association with
seller except as a customer.

http://stores.ebay.co.uk/ChaseInk?_trksid=p2047675.l2563

They are not the cheapest product on Ebay but for my printer the
cartridges contain more ink than the Epson originals. They are currently
approx £6 incl postage for a set of 4 (black + 3 colours).
