A Canon USA customer, David Leacraft, has recently filed a class-action lawsuit alleging misleading marketing and unjustified enrichment by the printer manufacturer.

Namely, Leacraft’s suit points to the inability of certain printer owners to use scanners or fax functions when the printers run out of ink.

The lawsuit seeks at least $5 million in bonuses, excluding interest, fees and legal costs.

Leacraft said that when using his Pixma MG6320 printer from Canon he discovered that the “all-in-one” device would refuse to scan or fax documents when the printer ran out of ink.

Since the ink was not necessary to perform scans or faxes, he argued that the printer functions should continue to work even without ink in the device. In that sense, the lawsuit states that consumers were misled when purchasing a product designed to create artificial and unethical problems associated with paying for ink levels even though there was no practical link between them.
