The core of printer consumables protection
In the beginning, there was no chip or chip counting function on the printing supplies. Therefore, when HP's laser printer first entered China, the introduction tips in newspapers and magazines (there was no Internet at that time) were all about how to fill HP's consumables with toner, because HP's consumables photosensitive drum had a much longer life than the toner inside, and it could usually be filled three times.
Consumables chips become a means for enterprises to identify genuine consumables, using third parties to lose their warranty.
1998, chips began to appear on printer consumables, and the same chips were used to force scrap consumables. At that time, there was no good way, and the move was highly controversial. Can car companies also designate energy suppliers? Turn off the engine without adding oil from a certain company? Printing companies do this. Although it is not ruled out now, there are still clauses that users who use third-party consumables during the warranty period will lose the warranty.
EU WEEE requirements have made printing equipment companies more tolerant of the recycling of consumables.
Now the whole world advocates 3R, so the printing enterprises are relatively convergent. This is an improvement. The key is that the EU's mandatory compliance with WEEE, or waste electrical and electronic equipment (WEEE), has led to a much greater tolerance for consumables in printing equipment sold in the EU than in China.
The cracked chip is cheap, a few cents to a few dollars a piece, with a supercomputer.
The road is one foot high, the magic one foot high. Chinese companies are also good at cracking chips. For this reason, they don't even hesitate to rent supercomputers to hack them. The printing equipment still on sale, as long as it is not too new, has cracking chips for printing, ranging from a few cents to a few dollars.
toner formula can't use it:
Laser printing technology relies on toner heating and sublimation to fix text or images on paper fibers, so preventing third-party companies from using the same formula as their own toner can solve many problems. In fact, there are a lot of tricks on the toner, which is a means to resist third-party consumables from the advanced level of technology.
