Preventing Sedimentation in Inks
The precipitation of the ingredients in the ink disables printing in normal color. So that the ink mixes well, shake the ink cartridge horizontally with a stroke length of around 5 cm (2 in.) from each end of the ink cartridge.
Remove the white ink cartridge, shake it 50 times (about 20 seconds), and then reinsert this cartridge.
The ink cartridges for colors other than white do not need to be shaken before every operation, but be sure to shake them when installing new ones.
The ingredients in white ink tend to settle. Each day, before starting the day's operations, be sure to shake this cartridge. Allowing the ink to stand without carrying out these steps can cause the settled material to harden, resulting in malfunction or other problems.
IMPORTANT:
Before shaking the ink cartridge, wipe off any ink from around its mouth. If you do not wipe off the ink, it may splatter when you shake the ink cartridge.
When you have finished mixing the ink, reattach the ink cartridge immediately. Taking time to reattach the ink cartridge will adversely affect the ink path.
Even if you are not using the printer, shake the white ink cartridge 50 times (about 20 seconds) once a week.
