Abstract:
1. A printing apparatus comprising: a printing material container including a storage device, a plurality of storage device terminals that are connected to the storage device, a first individual mounting detection terminal, a second individual mounting detection terminal, a first cartridge out detection terminal, and a second cartridge out detection terminal; an individual mounting detection portion that is connected to the second individual mounting detection terminal and that individually detects one of a mounted state and a non-mounted state of the printing material container; a cartridge out detection portion that is connected to the first cartridge out detection terminal and the second cartridge out detection terminal, and that detects a cartridge out state of the printing material container; a storage portion that stores a detection result in case that the cartridge out detection portion detects a cartridge out state; and a controller that, in an energy-saving mode, sets the individual mounting detection portion to a disabled state and sets the cartridge out detection portion to an enabled state, and if the cartridge out detection portion detects a cartridge out state, writes a detection result to the storage portion, when returning from the energy-saving mode to a regular mode, sets the individual mounting detection portion to the enabled state and accesses the storage portion, and if the detection result is stored in the storage portion, determines that the cartridge out state is present, even when the cartridge out detection portion does not detect a cartridge out state.
