Click Canon, Epson or HP link to buy a chip re-setter for your printer, or read this page to learn more about ink levels & ink monitoring.
Most ink printers use some way of ink monitoring. When a new cartridge is fitted, the ink monitor (level) is reset to full. And as the cartridge is used and ink is being depleted, the ink monitor tracks and displays the ink levels, so you know roughly how much ink you have remaining in the ink cartridges or ink tanks.
That's a good thing. It's handy to know how much ink you have left, instead of running out suddenly. Sure...and unless you are refilling your ink cartridges it doesn't really affect you a great deal. But if you are considering refilling, or would like to use ALL the ink that's in your printer cartridges, (rather then throwing out the 10-20% ink reserve), read on...
Printer makers are usingink chips(fitted to many printer cartridges and ink tanks) these days, to discourage ink refilling. And it's working well. There is not much to be gained, by re-inking a cartridge, if the printer will still see it as empty, reject it and not work.
What can you do about the chips ? How the ink level monitoring is achieved, how the information is stored, how it affects you and what you can do about it, depends on what printer make and model you use and what is currently available for it.
If you can't find the information (for your printer) on these pages, please contact us. It is difficult to keep the info up to date, as every new model is slightly different from the last one, and what works today, will not necessarily apply to a printer released next week.
Note: Many printers continue to print, even if the ink cartridges are declared "empty" by the printer software. Most low end Canon, HP, Lexmark and Dell printers don't need any external devices (chip resetters) or software to deal with ink level issues.
