INK-JET IMAGE FORMING APPARATUS

摘要

An ink-jet image forming apparatus is provided to circulate in between an ink tank and an ink head by operating a pump through a drive motor. An ink-jet image forming apparatus(1) comprises at least one pump(23), at least one pump operation unit(30), a drive motor such as a dead nozzle compensation motor(51) and a controller(60) for controlling the drive motor. The pump is installed on an ink cartridge(20), which is detachable to a body frame(10). The pump operation unit actuates the pump. If the drive motor rotates in a first direction, the pump operation unit is driven. If the drive motor rotates in a second direction, other parts of the image forming apparatus are driven.
