摘要： An ink-jet printer includes an ink tank for storing ink, a print head for ejecting the ink supplied from the ink tank to print an image on a paper sheet moved relatively to the print head, an ink-amount sensing section for sensing that ink remaining in the ink tank is decreased to less than a reference amount to generate a sense signal, and a print control circuit for driving the print head such that images are printed on the number of paper sheets ordered by each print job except in a state where the sense signal is generated by the ink-amount sensing section. In particular, the print control circuit is arranged to continue a print job being executed at a time when the sense signal is generated by the ink-amount sensing section.

摘要： An ink-jet printer with an ink nozzle purging device includes a valve equipped in a portion of an ink supply pipe extending from a pump to a printing head unit, and an ink urging unit which has a chamber equipped in a portion of the pipe between the valve and the pump, and further has an elastic member disposed in the chamber. The member accumulates an elastic force by a pressure of the ink entering into the chamber while the pump is operated with the valve being closed, and then urges the ink toward the printing head unit when the valve is opened to release the elastic force accumulated in the elastic member.

摘要： A nozzle unit is provided with nozzle heads of plural colors. Each nozzle head has a large number of ink-jet nozzles arranged side by side in the direction of main scanning. A head holder supports the nozzle unit in such a manner that the unit can move up and down between the printing position where printing is done on the printing sheet held on a rotating body and the non-printing position located above the printing position where the nozzle heads are maintained. The head holder is provided with a driving control circuit for driving the nozzle heads. The head holder, together with the nozzle unit, are movable vertically.
