Use Condition:
z
The print volume of the replacement life is based on continuous printing using A4 landscape sheets.
z
Use the replacement life only as a guide because it varies depending on conditions such as print
content, paper size, paper type, environment, and frequency of powering on/off.
z

initialize the life counter value of Fusing PV/Fusing Heat time.

replaced together with the FUSING UNIT.
z
The Transfer Roll(BTR) has no CRUM, and therefore the counter for it needs to be reset manually.
To reset the counter, refer to Chapter 6 "6.9.2 Display and Initialization of the Life Counter(Life)" and
initialize the life counter values of Trans Unit PV.
