Abstract
An ink jet recording method including the steps of providing a movable carriage having a sensor and which carries a recording head, as well as a plurality of flags in a movable range of the carriage. The method further includes the steps of determining a position of the carriage on a basis of an output of the sensor responsive to the flags, effecting a movement of the carriage through a predetermined distance on the basis of the output of the sensor, and effecting a predetermined operation on the basis of an output of the sensor.
Claims6
An ink jet recording method comprising the steps of:
- providing a movable carriage for carrying a recording head and having a sensor;
- providing in a carriage moving path a plurality of flags including a flag movable into and away from the carriage moving path in accordance with mounting and demounting of an ink cartridge;
- moving the carriage before executing a recording operation, during which the sensor senses a presence or absence of the ink cartridge by sensing which flag is present or absent in the carriage moving path;
- outputting an error signal when the ink cartridge is not sensed in said moving step;
- and
- effecting the recording operation when the ink cartridge is sensed in said moving step.
