Inkjet printer

An inkjet printer comprising:

• an ink cartridge comprising a plurality of ink containers storing a plurality of colors of ink and fixed to a main body of the printer;
• a printhead assembly comprising a plurality of nozzle plates, each nozzle plate comprising a plurality of nozzles ejecting ink supplied from one of the ink containers, disposed on the bottom of the ink cartridge, and arranged in a main scanning direction perpendicular to a paper feeding direction;
• a platen disposed a predetermined distance below the printhead assembly, the platen supporting a sheet of paper fed in the paper feeding direction, and having a plurality of slits formed in the main scanning direction to correspond to the nozzle plates for each color ink;
• and
• a wiping apparatus protruding through the slits, moving in the main scanning direction, and wiping the nozzle plates.

An inkjet printer comprising:
