The “Secret” that it speaks of sounds like buying the replacement sensor chips for the ink toners. The small chips can be found visible on the outside of each ink toner.

Order a set off eBay or some other vendor for each color. Each chip is color specific. Then pry the slightly melted plastic holding the old chip, and replace with a new one in the same place. Can probably use a hot glue gun to have it held in place firmly as well or other methods.

New sensor, printer thinks it’s a new toner. Viola!

I am interested to know the different ways OEM’s calibrate the end of life of a cartridge with their chips.

That is, manufacturers have an interest in reducing the
potential for refilling and remanufacturing their carts. Part of that effort is to put a life limit on the cart. How that life limit is calculated will vary but it has to have an outside limit, say printing entirely on draft or some minimal coverage. claims. Logically a higher coverage document could result in a runout before reaching the limit. I have heard some have a gear that winds down, another models the first 25% of print jobs and projects a run out point even if there was more toner left inside.
Can I have your thoughts on this topic?

I was looking for a replacement black cartridge for my laser printer, HP 2600n, on a popular auction site, and saw an ad for a CD that explains how to get an additional 600-1500 print sheets out of the cartridge. They are selling for around $8. I searched the internet and came up with nothing, but your site seems to know a lot about other printer stuff. Have you heard of this “secret” ? The ad says it is built in to help technicians service printers. One way or another, I might get ripped off, either $8 to learn nothing or more money on cartridges. Thanks for your time, great site.
