Abstract
An ink-jet recording head cleaning method and an ink-jet recording head cleaning cartridge for use in the method are disclosed. The cartridge 3 contains a cleaning liquid comprising water and a surfactant, and an ink cartridge is replaceable therewith. In cleaning a heating head 2 of an ink-jet recording apparatus having a removable ink cartridge, the ink cartridge is replaced with the head cleaning cartridge 3 to clean the head with the cleaning liquid contained in the head cleaning cartridge. The cartridge can be packed with a cleaning liquid holder comprising either a porous material or a nonwoven fabric made of chemical fibers. Tho head cleaning method is low-cost, does not impose any limitation on ink design, is free from the problem of printing density change which occurs during long-term use, and has an advantage that ink changes are easy.
