I knew that printers cheat you re ink usage, but I didn’t know there was a workaround for the problem. Here’s a tip from Oregon Expat:
So, now we know we’re being scammed. And those of us with an environmental bent are also fairly pissed off about the waste. But what can we do, when the printer locks up due to the “out of ink” message?
We can reset the chip.
Ink cartridge chips are the latest tool used by printer manufacturers to make sure that customers can’t override the low ink warning. The tiny electronic chips monitor ink usage, or, in many cases, simply count pages. Once the predefined threshold of a chip is passed, it will lock up the printer. The warning cannot be overridden.
But it turns out that there is a whole community of irritated printer owners who do not like being scammed. They have started up companies catering to other irritated printer owners, and one of the things they do is take ink cartridges and reverse engineer the chips. Then they build inexpensive “chip resetters” that exist for one purpose only: to reset the chip’s page count or ink level to zero [zero "usage," presumably].
