z   Replace the Maintenance Parts packed together with Cy an Ink Cartridge (380 cc /180 cc), Magenta Ink Cartridge (380 
cc)and White Ink Cartridge (380 cc) when you open the new  one. Clean the Caps and Wipers, replace the Wiper 
Cleaners, Fan Filter, Roller Felts (4), Flushing Plate Sponge (top) and Flushing Plate Felt (bottom) according to our 
maintenance schedule to maintain good print quality. Replace  them when you see the warning indicated on the display 
too. Print quality may be reduced by insufficient cleaning, e.g.  dirty printed materials, mis-firing. See 6-1-2. Replacing the 
Wiper Cleaner and Cleaning the Caps / Wipers, 6-1-3. Replacing Flushing Plate Sponge and Flushing Plate Felt, 6-1-4.

small amount of ink remains to avoid damage to your printer.

Pigments in the White Ink are sinking little by little all the  time. Hold the cartridge with both hands, upside down from the 
mounted position, and shake it in 1-2 minutes so that the pigments inside can be mixed enough. Do it one by one.
