The diagram on the below is a graph made from the data in the above table.
As explained on the previous page, the yield of the PM parts depends on the number of rotations
for a page. (This system for assessing yield is common in the printer field.) The expected yield of
all PM parts is calculated under a specific condition (3P/J, A4/LT long-edge feed, and 5% image
coverage ratio). P/J particularly affects the unit yield.

Note: Machine works for making patterns in process control self-check and lines
position adjustment (MUSIC) or performs idling when turning on the main switch.
While the machine is in these modes (self-check, MUSIC, and idling), the yield
counter (rotation counter) of maintenance kits counts up without making outputs.
Performing self-check, MUSIC or power OFF/ON of machine excessively affects the
.
unit yield
If making a meter charge contract with customers and if the meter charge fee is always the same
for all users, this may cause a reduction in profits depending on how a customer makes prints.
Therefore, it is recommended to consider the expected P/J and print volume for each user when
making a service contract.
