Replace the ink cartridge(s) that show asVery Low or Empty. Once replaced, select Ok to proceed with current operation. If the LCD control panel display still reads NOT FOUND after a new cartridge is installed, it instead of "GOOD", it may be installed improperly. Pull out the cartridge and insert it carefully, but fully until it stops. Do not force the cartridge to avoid any damage to the printer.
Please note that without installing all 6 cartridges, the printer will not print. Even when you do not use the printer for an extended period of time, do not remove the ink cartridges from the printer. Even if the ink cartridges are empty, keep the cartridges installed to help keep air away from the ink delivery system.
For Printer storage for an extended time period, it is recommended to flush ink carts with Cleaning Solution then replace then with HV storage solution. See section 6 of your User Manual: Switching from Ink to Cleaning Solution Using the Startup Fill Function. AnaJet recommends the use of genuine AnaJet Ink cartridges which have been specifically developed for the AnaJet 3000 and AnaJet 6000 printer.
Use of other inks or tampering of the ink cartridge will not only produce poor quality prints but may damage your printer. AnaJet is not responsible for any damaged caused to the printer through the use of third party inks. If you do not have a replacement cartridge, leave the old cartridge in the printer until you are ready to replace it with a new one.
