(3) New Release
• After replacing a fusing unit or transfer belt unit, perform New Release to clear its life counter.
1. Touch [Counter] -> [Life] -> [New Release].
2. Open the front door or the lower front door.
3. Select a unit where New Release is made.
4. Press the Start key and perform New Release.
(4) New Release Disable mode
• To enable a unit that is used temporarily for troubleshooting to be used again as a new unit in another machine, the New Release
Disable mode is provided.
• Counts how many sheets have been ejected. The counter increases by 1 per every 216 mm
in the paper feeding direction and shows the total count. For paper length less than 216 mm
in the paper feeding direction, the counter uses 216 mm as the paper length.
• Counts how many hours the transfer belt unit has turned.
• Counts how many sheets have been ejected. The counter increases by 1 per every 216 mm
in the paper feeding direction and shows the total count. For paper length less than 216 mm
in the paper feeding direction, the counter uses 216 mm as the paper length.
Counts how many hours the transfer roller unit has turned.
• bizhub C368/C308/C258: Not used
• bizhub C658/C558/C458: Counts how many sheets have been printed for color printing and
black printing.
For the life counter, value based on the calculation below is displayed.
Value (1) or (2) below whichever is larger than the other one
(1) Number of prints for black printing
(2) Number of prints for color printing ÷150,000×300,000
(However, due to the formula for each internal counter for CMY and K, the toner filter counter
may not count even when black and white printing is executed.
Besides, the counter life threshold during printing with K only (300,000) is two times as large as
that during printing with CMY only (150,000). Thus, the number of sheets printed with CMY only
are doubled to count.)
• Counts how many hours PC drum has turned.
• Counts how many sheets have been printed. The counter increases by 1 per every 216 mm
in the paper feeding direction and shows the total count. For paper length less than 216 mm
in the paper feeding direction, the counter uses 216 mm as the paper length.
