A leakage detection apparatus and method for a multi-channel inkjet cartridge. The leakage detection apparatus includes a plurality of electrodes and a controller. Each of the electrodes is disposed in one of channels of the inkjet cartridge respectively, and contacts a reagent in the corresponding channel. The controller is coupled to the electrodes, and detects leakage between channels.

A method of prolonging the lifetime of a thermal-bubble-ink-jet print head. A first pulse is provided to a heater of the print head for generating a first bubble to expel an ink drop. A second pulse is provided to the heater after a delay time for generating a second bubble is generated. The second pulse is not large enough to expel another ink drop.

A holographic spectroscope for a two-motor reflection system for generating scanning patterns in which a light beam is first reflected by a first reflector connected to a first motor electrically connected to a first control circuit. A second reflector for reflecting the light beam reflected by the first reflector is connected to a second motor electrically connected to a second control circuit and to form scanning patterns. A holographic spectroscope for diffracting the scanning patterns is mounted in the optical path of the light beam from the second reflector. Therefore, the scanning patterns can be improved to be more variable.
