In discharge recovery processing, a continuous sheet 23 is moved from a facing position facing a head portion 21 to a first position (in the down direction in the drawing) as an evacuating position in the discharge recovery processing, thereafter, a discharge recovery processing unit 22 in the standby mode at a second position (in the up direction in the drawing) different from the facing position is moved to the facing position, and the discharge recovery processing is performed. In the discharge recovery processing, the head unit 21 is not moved and therefore the preferable positional reproducibility is obtained after ending the discharge recovery processing.

A printer system includes a host computer, K, C, M, and Y printer elements for four colors, a paper feeding section, and a head cleaning section. The printer elements each include a head controller and print head groups. The head controllers are connected to the host computer via SCSI interfaces in a daisy chain. When printing, the host computer transfers information, such as an image-printing region, image-printing data, to the head controllers via the SCSI interfaces, thereby executing image printing. The printer system can control a large number of print heads with a simple configuration and also can perform high-accuracy image printing.

An image projector projects images according to inputted image data. A light source unit has at least a plurality of LED light sources configured as a single unit for emitting an illumination. A space modulation element is modulated according to inputted image data. An illumination optical unit leads the illumination light emitted from the light source unit, and illuminates the space modulation element. A projection optical unit projects an image illuminated by the illumination optical unit and modulated by the space modulation element. The light source unit is configured removably from the image projector.
