Array-type ink cartridge

An array-type ink cartridge comprising:

• a plurality of ink cartridge modules each comprising a pair of heads that are misaligned in a length direction such that a print width extends;
• a fixing plate fixing the plurality of ink cartridge modules and aligning fixed locations such that the plurality of ink cartridge modules form an array in a length direction or a width direction of the plurality of ink cartridge modules;
• first and second circuit boards respectively combined to one side surface and another side surface of the plurality of ink cartridge modules forming the array and comprising a circuit for controlling the plurality of ink cartridge modules;
• and
• a flexible printed circuit board for connecting the first and second circuit boards on a circuit configuration.
