ink jet refills : LUSENET : WebDevelopers : One Thread

I got a re-inking kit from which contains the proper type of ink for HP printers. (Works great)

The problem some of you might be having is because HP does not want you to refill your cartridge, so they made the computer and/or printer keep track of the cartridge's serial number. If you place the refilled cartridge back into the printer, it will not work.

To work around this, you can buy several cartridges, or:

Unplug the computer cable.

Turn the printer off.

Turn printer on and open cover.

Remove the cartridge.

Using a strip of scotch tape, cover the 3 upper contact points on the far left contact column in the copper plate, with the printhead facing down.

Re-install the cartridge into the printer.

Close cover.

Turn off the printer.

Turn on the printer.

Open the cover.

Remove the cartridge.

Carefully peal the tape off.

Now do the same things as step 5, only do it to the far right contacts on the copper plate.

Repeat steps 6-12

Re-install the cartridge.

Reconnect the printer cable.

I have a HP [printer, and refill the black cartridge. There are two things I've learned about doing this. First, before you refill it, hold it upside down, and wipe off the contacting areas with a alcohol swab. Make sure that no fibers are left.

The other thing, and is the most important. Make sure that the opening, that you used to fill the cartridge, is sealed air tight. If any air what so ever can get in, then you'll have ink running out of the bottom. I've found that a little bit of rubber cement works real well for this.

The other thing you might want to do, is use a remanufactured ink cartridge. Office Depot sells then for well under what a new cartridge does. There might even be places on line to get them. This is what I use for the color cartridges.

edited to add: There is no one ink for every printer cartrage. Some use a thicker ink, some a thinner. Most office supply stores, have special refill kits for each manufacture.

I have an HP printer. I ordered ink from Mr Inkjet on the net. The first cartridge I filled worked great. When it ran out of ink I filled it again and it wouldn't work. I discovered that the ink was dried on the bottom and soaked it in a very little amount of warm water , just enough to cover the bottom of the cartridge, till the dried ink came off. I carefully dried it by dabbing and it worked great. I did overfill one and the ink leaked out into the printer. Took the printer and cleaned the inside wirh cotton swabs and q- tips. Left the cartridge laying out all night and it worked the next morning ok, no leaking. I've saved a lot of money this way. For me its worth learning how to do it. Haven't tried with a color cartridge as I don't print much in color.

Many of the newer HP printers have a memory for the print cartridge. You need to exchange carts. 3 or 4 times with different carts. and it will forget the one that you refilled. Save old carts. or borrow from friends. I use Fillmore ink and have not had any problems. Have been doing it for years. Saved lots of $$$$$!

The clerk did mention that he took a tiny drill and made a hole in a new cartridge, filled it and then sealed the hole back up with plumber's putty and it worked fine.

I've tried to refill them in the past and didn't have much success with it.

I refill with whatever ink that happens to be sitting around, with that big syringe that comes with some kits.

Then ... I seal the hole with hot melt glue. I think the key is to have a completely sealed cartridge (I don't recall squeezing the cartridge, but that action implies the cartridge needs a negative air pressure).

Clamp or Squeeze..........

My 930 Series HP printer has a B&W cartridge that needs to be squeezed before being sealed. I use "Vise Grip" pliers.

My 300 Series "All in one machine" has a cartridge that needs to sit on it's side for a few hours after injecting the air to the cartridge.

Hope that helps.

PS...The FilmoreInk comes with good directions.

IF you follow the directions exactly for HP, it works just fine. You must do it in the right order as well. there are 2 holes that must be taped, and air extracted from the inside of the cartrige or the air pressure WILL cause the ink to leak. I have been using the SAME cartrige now for 2 years as well and it is just now getting worn out. Time for an official new one.

I have also had them leak from not performing the process correctly.

The ink is not as good a quality as the official new ones, it's not as water resistant, takes longer to dry, and is of a slightly different shade.

Hint...don't let your cartrige run completely dry before refilling. It's very hard to get the ink to flow properly if you let it run dry, then fill. Another hint..if cartrige gives problems after refilling, let it set for about 24 hours to readjust the pressure inside.

Yes, clean the heads gently, also, clean inside where the ink goes in the printer.

After replacing, test with a word document. A long one will sometimes get the ink flowing.

Yes, it can be very messy...specially if you let it run dry.

It needs to be squeezed before you seal it.
