L-6534VW Operation Guide Mixing and Replacing Ink Cartridges Stirring Ink by Shaking the Ink Cartridge You need to stir the ink periodically to prevent sedimentation from occurring in the ink cartridge. The mixing procedure is the same as the procedure used when replacing an ink cartridge. U “Replacing Ink Cartridges” on page 234 The frequency and number of times to shake the cartridge changes depending on the color. Since a message is displayed on the touch panel informing you when you need to shake an ink cartridge, follow the on-screen instructions to shake the cartridge. Note:
❏ If you have not used the press for over one week, only shake the white ink cartridge back and forth 50 times each, face up and face down. ❏ If you are not going to startup the press for more than two weeks, replace the white ink in the print head with storage liquid to prevent sedimentation and to protect the print head before shutting down the press.
