It is no secret that the main income of companies producing inkjet printers is formed not from the sale of printing devices, but from the subsequent supply of their consumables. But not every user is able to pay $ 50 for one cartridge to the printer. In addition, the prices of some sets of these consumables, which include several individual cartridges, are going wild for 8 thousand rubles.
Having found out how much new cartridges cost, many try to find out if there is any specialized software / program for resetting cartridges or how to refill them.
Given such a pricing policy of manufacturers, as well as huge demand from below, it is not surprising that alternative refueling options for inkjet technology began to appear in the world. A variety of CISS technologies and systems (continuous ink supply system) have suppressed products that are “original” both in the place of production and in cost in the printers of end-users.
The main players in the inkjet market, HP, Epson and Samsung, felt threatened by their almost exclusive position and began to develop retaliatory security measures designed to prevent the cartridge from running out of ink or replace it with a compatible one.
So on the new cartridges appeared electronic state accounting systems. When ink runs out, their task is to signal to the printer that this cartridge is unsuitable for further work, even if ink is then added to it again. In such a simple way, they closed a loophole with which the cartridge could be refilled an infinite number of times.
Now the microchip integrated in each cartridge is equipped with a counter, which, using information on the maximum possible number of printed pages, compares the number of sheets already passed through the printer with this maximum value. As soon as according to the manufacturer’s calculations, not a drop of ink should remain in the tank, the printer gives an error and requires replacing the ink tanks.
But this system has one significant drawback. For example, you have a lot of work on printing sheets filled with text at 10%, you, of course, expect long work from your printer. But after all, each sheet is considered a system, and now there is another 50% of ink in the banks, and the printer already gives a warning about the need to quickly replace the cartridges, since, according to the counter, you have used up all the ink.
What to do in this case? Throw away ink tanks and buy new ones?
Naturally, service workshops that earned money from refueling various printers immediately began looking for ways to reset cartridges that were blocked by the ink level monitoring system.
There are several ways to deal with this problem.
If a laser chip allows simple replacement of the chip, then in inkjet printers it is much more difficult to do, since the chips are executed in one unit there along with the control circuit of ink tanks that supply ink for printing. So the easiest way is to reset the cartridges.
For many Epson printers, there are programmers with which you can easily and safely perform this operation. Cartridges can also be reset to zero using a service program, but I would not advise doing this to people who do not fully know what they are going to do and how. Such methods are still better left to the engineers.
And for ordinary users, zeroing programs are suitable, a lot of universal versions have been written for many types of cartridges.
For HP printers with a series of ink hoppers starting at 9XX, there is an unconventional way to reset cartridges. The fact is that the cartridge identifier in this series is stored in the printer itself, and in order for the latter to accept the refilled cartridge, several simple steps should be "turned". Print a few test pages, each time replacing the cartridges with others, after a few prints, the printer will forget the ID of your old cartridge and after it is installed back will perceive it as a new one.
