You could try buying an Inktec tricolor refill kit. This comes with a cartridge holder, ink, and four syringes. After using the first three syringes to fill the cart, the fourth is used in conjunction with the holder to draw some ink out through the nozzles to clear out any air blocks.

Many, if not most, Linux programmers feel that Linux users don't need that much hand-holding, and many, if not most, long-term Linux users agree. TJ -- Life isn't fair. It's not meant to be.

At least, that's the way it works with my #57 cartridges. Thanks, TJ! That could have been it. I /think/ I can work out something similar with what I already have on hand, but if not I'll give that a try. I think Staples (office supply store chain) carries those. >> Meanwhile I'm experimenting with HP 22's 'A' and 'B' which I thought I'd >> killed by letting the ink run out before trying to refill them.

NOW you tell me! :-) Thanks for the tip; I'll pick up some distilled water and try that the next time. My preliminary conclusions are that isopropyl alcohol cleans HP color carts, while ammonia ruins them. >> someone could eventually write a program (perhaps for /etc/cron.hourly) >> to check at regular intervals, and notify the user if the levels were >> below some threshold. > > Don't look for it any time soon.

That's why I said "someone could write" instead of saying that I would. ;-) Adam

No > conclusions yet. :-) The sponge provides some back pressure to keep the ink from dripping out the bottom of the printhead. Without the sponge the ink will dribble out, at best causing a mess and at worst damaging the printer and perhaps your desktop. Ink delivery systems without sponges will have some other design to keep the ink in the cartrdige. Examples include the spring bag system used in the #45 cartrdiges.

Bob, correct me if I'm wrong, but I believe he retired from HP just a couple of years ago or so after many years there. TJ -- Life isn't fair. It's not meant to be.

But while it's quite possible to know a little about many things, and a lot about a few things, it's next to impossible to know a lot about everything. We all have our specialties. HP printers are one of Bob's. It isn't one of mine, and comments you have made show that it isn't one of yours, either. Therefore, his knowledge of HP printers is likely to be much more extensive than mine or yours. I never worked for HP, either. Except for a two-year stint with a newly-minted engineering BS, working for the US Army at the request of Richard Nixon, I have been self-employed as a farmer since the age of 12. While in the Army, my specific job involved operating several pieces of HP equipment, including minicomputers, at a research facility. But I wouldn't dream of citing my experience with 38-year-old technology as a qualification for understanding modern inkjet printers. BTW, it's possible to disagree with somebody and remain respectful of that person. You should try it. TJ -- Life isn't fair. It's not meant to be.
