How to Display Low Ink Warning Correctly
• Reset the ink counter every time you install a new ink tank.
The ink counter cannot work correctly unless you synchronize it with the actual ink
level. The ink counter can be reset only when a new ink tank is installed.
• Do not reset the ink counter of an ink tank in use.
Synchronization of the counter and the actual ink level will not work properly.
Important If you did not reset the counter when you installed the current ink tanks,
the low ink warning may not function correctly, until the next time you
replace the ink tanks. Also, be sure to treat both counters separately.
