HP Designjet 4020 and 4520 Printer Series - Maintain the ink cartridges

During the normal lifetime of a cartridge, no specific maintenance is required. However, in order to maintain the best print quality, you should replace a cartridge when it has reached its expiration date, which is the date marked on the cartridge plus 6 months.
