CARTRIDGE WITH INK LEVEL MONITORING FOR A PEN-LIKE MODULAR PRINTING DEVICE

摘要

A cartridge for a pen-like modular printing device is provided. The printing device includes a chassis defining a print media feed path, a feed mechanism to feed said media along the feed path, a feed path width printhead for printing on said media, and a controller for controlling the feed mechanism and printhead. The cartridge defines at least one ink reservoir which is operatively arranged in fluid communication with the printhead via ink channels defined in the chassis. The cartridge further has an integrated circuit for monitoring ink levels in the reservoir, with the integrated circuit operatively arranged in signal communication with the controller. The cartridge is shaped and configured to be received in the pen-like chassis.
