USA versions of the Epson SureColor printers are locked
You will see support for the SureColor P-printers on InkjetMall. Not all of them...but, most of them at this point.
Epson has locked the North American SureColor P-series printers against use with 3rd party cartridges. The models that are affected as of this writing are the P400, P600, P800, P6000, P7000, P8000, P9000, P10000, P20000. Epson clearly states in their literature and website that these models are designed to work only with Epson Branded cartridges "and not with other brands of cartridges or inks."
These same printer models however, can be used outside of North America with other brands of cartridges and inks. Refillable cartridges work with both the European and Asian versions of these printers. But, Europe and China enforce their anti-competition and consumer protection laws. The European and China region printers do not have the same main board electronics that the North American versions have.
This type of consumable choice prevention activity is not limited to Epson. Other OEMs are doing this also. Recently, HP locked its printers against use with 3rd party carts in the USA. HP customers were so outraged that they filed complaints with the FTC and other consumer watchdog organizations. HP was pressured into issuing both an apology and a firmware upgrade to unlock these printers.
We have imported for example, the P810 from Hong Kong which works with refillable cartridges. The only way in which to use the North American P800 is by installing our chip decoder board.
The North American P600 will not read with accuracy the remaining ink levels in a cartridge that is similar in size to Epson. So we developed a double-capacity cartridge for the P600.
The North American P400 will not allow some chips to auto-reset, so we are using special chips.
The North American P5000 will probably require a chip decoder board, but the board is still under development.
The North American P6000, P7000, P8000, and P9000 keep track of individual chip ID numbers, and if the same number is used twice, the printer will become inoperable. Some vendors in the USA are now selling refillable cartridges and selling them with replaceable chips that have up to 5 different chip ID numbers. We are not selling these at this time. The first generation of these chips were very unstable. The next generation has improved. We're holding out for a better solution or a decoder board. We feel we could better support a permanent solution to the problem, rather one that is still in development.
Beginning on January 22, 2018 we began supporting the P400, P600, P800 printers with both cartridges and ink sets at InkjetMall. This includes ConeColor, InkThrift, and Piezography. On this same date we began supplying inks only to the P6000, P7000, P8000 and P9000 printers. Our customers will need to source refillable cartridges for these printers from other sources.
