Method and a device for detecting an ink cartridge

摘要

A device and a method for detecting the presence of an ink cartridge in an ink jet printer starts with powering on a printer. Second, the carriage is moved until it reaches the home position. After the carriage has been initialized, the carriage continues to move for a predetermined distance. If a sensor detects the presence of an ink cartridge then a second detect signal is sent to the controller. Otherwise, an error signal is sent from the controller to alert a user that the ink jet printer requires the insertion of an ink cartridge.
