KX-P8420 has a front panel menu function to show how much percentage of each consumable life remains to

be used. Please note that the values shown here is just the approximate value and are not always correct. So the

consumable wearing warning message might occur regardless of the displayed values.

Page Count - shows the pages your KX-P8420 has printed since your

purchase of the printer.

Toner Cartridge - shows the percentage of CYAN, MAGENTA, YELLOW and BLACK toner cartridges remaining.

- The remaining value of Toner become 0% when Low <Color> Toner message is shown. The value return to 100%

after the toner is replaced. Or may become 100% before replacement because of toner low sensor instability.

The printer recognize the toner replacement if low toner is not detected more than 400 pages.

- The value become incorrect when the replaced cartridge is a starter kit because P8420 assumes new cartridge is

not a starter kit.

- If you replace the toner cartridge before Low <Color> Toner or <Color> Toner Empty is displayed, the value of the

toner cartridge remaining will be incorrect.

- The remaining value depends on how much coverage in the printable area are used.

- Theoretically the remaining value should be around 0% just before Low <Color> Toner message is shown. But

actually it does not especially when an average of coverage is too large or small. Because actual toner usage

depends on many factors(ex. coverage, printing pattern, temperature) When the average is too large, the value tend

to become 0% long before Low <Color> Toner message is shown.

Imaging Unit - shows the percentage of the life of color imaging unit remaining.
