Life Value Count Condition
10,000,000 Counts up when paper passes through the Fusing Unit Exit Sensor.The count value is
determined based on multiples of paper length in 216 mm.0 mm < Paper Length <=
216 mm: 1 Count Up216 mm < Paper Length <= 432 mm: 2 Counts Up
To clear the counter, enter the HFSI Counter Read / Clear Mode and select [Clear] ->
[Start] to clear it to '0'.
This can count up to the maximum of 99,999,999 and the maximum value is retained
until the counter is cleared.
17,500,000 Counts up when paper passes through the Fusing Unit Exit Sensor.
The conversion value is calculated with 1 sheet of A4 L being equivalent to a value of
100.
Count value = Paper Length [0.1 mm]/21
To clear the counter, enter the HFSI Counter Read / Clear Mode and select [Clear] ->
[Start] to clear it to '0'.
This can count up to the maximum of 99,999,999 and the maximum value is retained
until the counter is cleared.
50,000 Counts up at feeding from MSI.
To clear the counter, enter the HFSI Counter Read / Clear Mode and select [Clear] ->
[Start] to clear it to '0'.
This can count up to the maximum of 999,999 and the maximum value is retained until
the counter is cleared.
50,000 Counts up at feeding from Tray 1.
To clear the counter, enter the HFSI Counter Read / Clear Mode and select [Clear] ->
[Start] to clear it to '0'.
This can count up to the maximum of 999,999 and the maximum value is retained until
the counter is cleared.
300,000 Counts up at feeding from Tray 2.
To clear the counter, enter the HFSI Counter Read / Clear Mode and select [Clear] ->
[Start] to clear it to '0'.
This can count up to the maximum of 999,999 and the maximum value is retained until
the counter is cleared.
