Chip Shortage Repercussions Continue

According to Epson, there is no chemical or formula difference between the old and new inks. The current ink cartridges have a chip that notifies the printer to send a low ink warning or to replace cartridges. The new ink cartridges will operate without that chip. Ink levels will instead be determined by an internal droplet count done by the printer. This measurement method may lead to an earlier indication of low ink levels than the previous cartridges. To compensate for this potential variance in ink level reporting, Epson is lowering the end user purchase price.
