ABSTRACT:
An ink jet apparatus, used with an exchangeable ink jet cartridge having an ink jet head and an ink container, includes a cap, a sucking device and a controller. When the cap caps the ejection orifices of the recording head, the sucking device sucks ink from the ejection orifices. The controller controls the operation of the cap and sucking device. After a sucking operation is performed, the cap is held away from the ejection orifices for a predetermined duration of time; the capping and sucking operations are then repeated.
