PROBLEM TO BE SOLVED: To provide a printer which can simply carry out alignment of each color at a printing position and can beautifully print visible information, and to provide a recording medium drive unit. SOLUTION: The printer is equipped with a spindle motor 22 which rotates an optical disc 1 attached removably, and a printing head 31 which is opposed to a label face of the optical disc 1 attached to the spindle motor 22 and can print the visible information such as characters and patterns by ejecting ink droplets to the label face. The printing head 31 has four sets of ejection nozzles by color 45-48 which eject ink of four colors. The four sets of ejection nozzles by color 45-48 are arranged in one array. A head moving mechanism is equipped which moves the printing head 31 in a predetermined direction based on a rotation center position of the optical disc. COPYRIGHT: (C)2008,JPO&INPIT

PROBLEM TO BE SOLVED: To calculate the residual quantity of liquid in the ink tank of an ink jet printer equipped with an ink supply unit for supplying ink to a print head. SOLUTION: In the ink jet printer comprising a print head 1 for ejecting ink from an ink ejection nozzle 10, and an ink supply unit for supplying ink 7 to the print head 1, the ink supply unit comprises an ink tank 6 containing the ink 7, an auxiliary tank 3 for temporarily storing the ink 7 supplied therefrom and supplying the ink 7 to the print head 1, and a liquid quantity detector 4 for detecting the quantity of ink 7 in the auxiliary tank 3. Quantity of ink 7 supplied from the ink tank 6 to the auxiliary tank 3 is detected using the liquid quantity detector 4, and the residual quantity of ink 7 in the ink tank 6 is calculated based on the quantity of supplied liquid.

Abstract:
PROBLEM TO BE SOLVED: To efficiently maintain the liquid discharging performance by reducing discharge defects of a liquid by a liquid discharging head in a liquid discharging performance maintenance method of a liquid discharging apparatus which discharges the liquid from liquid discharging nozzles of the liquid discharging head. SOLUTION: An ink (predetermined liquid) (i) within a printing head 22 which is supplied from an ink tank 4 to be discharged from the ink discharging nozzle 40a is ejected out of an ink-sending pipe 159, and bubbles mixed in the ink (i) are removed, whereby the discharge defects of the ink (i) are reduced in the liquid discharging performance maintenance method. After the execution of bubble removal through ejection of the ink (i) in the printing head 22 is started, the bubble removal is continuously executed until a fixed time passes since the state that no bubbles are present in the ink (i) ejected from within the printing head 22 is detected. The ink discharge defects of the printing head 2 are thus reduced, and the ink discharging performance maintenance is carried out surely. COPYRIGHT: (C)2005,JPO&NCIPI
