Specialty Inks The term "specialty inks" is used for white and metallic silver inks. White and metallic silver inks are prone to settling (components settling to the bottom of the liquid). Using the ink in this state can cause a decline in print quality and printer malfunction. This section describes precautions for handling white and metallic silver inks. The S30670 does not support specialty inks. Cautions ❏ When specialty inks are installed, maintenance will be performed automatically to prevent ink accumulating in the printer and causing clogs. Because turning the printer off prevents maintenance being performed, leading to printer malfunction, we recommend that the printer not be turned off. ❏ White and metallic silver ink cartridges must be stored flat (i.e., laid on their sides). If the cartridges are stored on end, agitating the cartridges before use may fail to dissolve the materials that have precipitated from the ink (i.e., settled to the bottom of the liquid) during storage. ❏ If the printer will not be used for seven days or more, use a cleaning cartridge (available separately) to wash the heads. You will have to drain all channels, not just the white and metallic silver. Leaving the heads unwashed causes permanent clogs. See "The Maintenance Menu" on page 159 for more information. Maintenance The maintenance required to keep the printer in good working order can be divided into routine maintenance and tasks that the printer performs automatically. Auto Maintenance To prevent malfunctions caused by settling of the white and metallic silver inks, the printer automatically cycles the ink if no operations are performed for some time after printing or after the printer is turned on. Automatic maintenance is performed if the printer is on; no user intervention is required. Daily Maintenance ❏ White and metallic silver ink cartridges must be removed and thoroughly shaken once every 24 hours. See "How to replace" on page 143. Introduction 35
