Life value of consumables and parts

• The life counter value of each materials and parts is available from [Service Mode] →
[Counter] → [Life].
• Life specification value means an actual life terminated when prints are made under the
conditions as defined in the next section, "Conditions for life specifications values."
The actual life may vary greatly depending on how the machine has been used and other
factors.

*1: A waste toner full condition is detected with detecting the actual waste toner emissions.
*2: Once the toner-full is detected, it has to be replaced with the new waste toner box in
order to reset.
*3: The initiation of any new print cycle is inhibited when the max. life value is reached.
*4: The mark "M" is indicated the value of the number of distance through which the PC
drum has run translated to a corresponding value of the number of hours and the value.
