manufacturers do not want you to refill inkjet cartridges - why?-
inkjet cartridge sales are a huge source of revenue them -
anything they do which makes it more difficult for the end user to succeed
means a greater chance that their cartridge sales will increase! We supply
the major manufacturers inkjet cartridges but our main focus is in supplying
alternatives this includes - compatible inkjet cartridges -
recycled inkjet cartridges and professional refill systems designed for
particular cartridges - Our aim is to help you substantially reduce your
printing costs. This page is a refinement in that process and aims to defeat
a recent mechanism introduced on newer HP inkjet printer cartridges where
they have included software that comes with their printers, a "toolbox" that
has a section called Estimated Ink Level. A useful tool that allows
you to keep track of how much ink is left in your cartridges so you don't
start a big print job and get stranded out of ink in the middle of it.
If you refill your cartridge, it will read as low or empty when you try to
print with the cartridge. How does HP do it? They have embedded
a serial number in the contact strip located on the back of the cartridge.
The printer remembers that serial number and gives the message of low or out
of ink. The internal memory is located in the printers firmware and is
not in the software. It will remember the previous two cartridges ink
level. The process below will reset the ink levels so your Estimated Ink
Level will read full again.

METHOD 2 -
On some models the above procedure won't
work, and you'll have to fool the printer by keeping three cartridges on
hand (these cartridges can be old, empty cartridges). This works
because the printer only remembers the last TWO cartridges which were in it.
The procedure is as follows:
- Cart #1 (empty) is removed for
- Cart #2 is installed
- Cart #2 is removed
- Cart #3 is installed
- Cart #3 is removed
- Cart #1 (refilled) is installed.
The printer now thinks that the filled cart is new.
ANOTHER METHOD? - METHOD 3 - One of our
customers used the procedure listed above to reset the ink levels on the
cartridges HP 56 & 57 in an HP Photosmart 7260. this worked fine for the
color #57 but he could not get the Blk #56 to reset using the procedures
listed above, however he got it to reset by applying tape per step 1,
reinstall, power down printer, power up printer.
Add tape per step 2, power down printer, power up printer.
Remove tape applied in step 1, reinstall, power down printer, power up
Remove tape applied in step 2, power down printer, power up printer.
At this point going to Start, Settings, Printers, HP 7260, Properties,
services, service this device, select the "Estimated ink level" which showed
a full ink level.
At no time in the process for either cartridge did the printer / software
indicate that there was a problem with the cartridge and want to run an
alignment, which is why he substituted a power down.
method I heard of which might work on HP Lexmark and Dell is to remove both
cartridges from the printer, Power the printer on / off at wall supply about
6 times - leave 30 seconds or so between each power on / off to the printer.
The idea here is that the printer with no cartridges in has no cartridge "To
memorize" and that at the end of the procedure any cartridge introduced is
treated as a "New cartridge" - No confirmation yet that this method is
2. To reset the HP 56 black ink
cartridge or HP 57 colour ink cartridge, first tape over the contact pointed
to by the arrow in the diagram on the left.
3. Install the cartridge back into your HP printer with the first contact
covered with tape.
See below for illustration of contacts. (One of the little gold-coloured
squares is called a contact.)
4. The printer will tell you that there is a problem with the ink cartridge.
Click "ok". The printer will then start to print an alignment page.
Let the printer print the alignment page.
5. Remove the cartridge from the printer again. Leave the first piece
of tape on the contact first covered. Cover the second contact shown
in the picture on the lower left for the black cartridge or the contact in
the picture on the lower right for the color cartridge. The second
contact on the HP c6656a black cartridge to be covered is the top square on
the next to last row from the left. The second contact to cover on the
HP c6657a cartridge is the top square on the last row from the left.
6. Install the cartridge into the
printer again. This time with both contacts being covered with tape.
7. The printer will go through the same process as before, telling you there
is a problem with the cartridge. Again, click "ok". The printer
will start to print an alignment sheet. Again, let the printer finish
the alignment page.
8. Remove the cartridge once more from the printer. Remove both
pieces of tape used to cover the contacts. Make sure that there isn't
any residue left from the tape on the contacts. If you do see residue,
gently clean the contact with rubbing alcohol.
9. Install the cartridge on final time into your HP printer. The
cartridge will now be read as new and full of ink.
