For years, printers have been encumbered with digital rights management systems that prevent users from buying third-party ink and toner cartridges. Printer companies have claimed that their chip-enabled cartridges can "enhance the quality and performance" of their equipment, provide the "best consumer experience," and "protect [the printers] from counterfeit and third-party ink cartridges."
[...] "Due to the worldwide continuing shortage of semiconductor components, Canon is currently facing challenges in procuring certain electronic components that are used in our consumables for our multifunction printers (MFP)," a Canon support website says in German. "In order to ensure a continuous and reliable supply of consumables, we have decided to supply consumables without a semiconductor component until the normal supply takes place again."
[...] But Canon has been having a hard time getting chips amid the shortage, so the company is telling owners of its imageRUNNER large-office printers how to defeat its own protections against cartridges that don't have chips.
The software on these printers comes with a relatively simple way to defeat the chip checks. Depending on the model, when an error message occurs after inserting toner, users can press either "I Agree," "Close," or "OK." When users press that button, the world does not end. Rather, Canon says users may find that their toner cartridge doesn't give them a low-toner warning before running empty.
