Abstract
The unjamming process is conducted through an opening formed on a lateral side of a housing of the printer. A recording medium conveying unit of the printer does not get exposed to outside. The printer also inhibits inaccurate ejection of ink from recording heads because of the unjamming process. For the unjamming process, the recording medium conveying unit is moved away from head surfaces. This constitution prevents vibration or shock on the recording heads when a recording paper is removed, prevents breakage of menisci formed on respective nozzles of the recording heads, and furthermore prevents ink from being pushed outside of the nozzles, or inhaled toward an ink tank because positional relation between the recording heads and the ink tank does not change. Therefore, inaccurate control over ejection of ink can be inhibited.
