Count method
Converted to A4
equivalent or non-
dependent on size
Counts up after
paper has passed
the write sensor
Count-up when the
MPF (MPT) hopping
has succeeded.
Count up when the
tray 1 hopping has
succeeded.
Count up when the
tray 2 hopping has
succeeded.
Number of sheets that has
passed the fuser unit in color
mode is counted up when
the print job is completed.
(*1)
The value is the A4/Letter
converted value.
Regarding the A4/Letter
conversion, refer to the sheet
“page count rules".
Number of sheets that
has passed the fuser unit
in monochrome mode is
counted up when the print
job is completed. (*1) Even
when a color print speed
is selected, there can be
cases that the print is in
monochrome mode.
The value is the A4/Letter
converted value.
Regarding the A4/Letter
conversion, refer to “rules” of
the A4/Letter conversion.
Handling when paper jam
occurs
Count is not executed during the feed paper (hopping) jam and feed jam (380).
Jams other than those are counted.
Because the total number of printed sheets are counted when top end of paper has passed the write sensor, the
feed jam (380) is included in the condition of not counting the jam if jams are classified by the jam types.
When jam occurs before paper passes the fuser unit, the
jam is not counted. Jams after paper has passed the fuser
unit are counted.
Handling during the
Duplex print
Front and rear
sides of papers are
counted. (+2)
Only table is counted. (+1) It is counted as 2 counts. .
If color page exists within a pair of two pages, the number
of color prints is incremented by +2. If color page does not
exist within a pair of two pages, the number of monochrome
prints is incremented by +2.
Reset condition None None (1) When ROM is replaced by the ROM of different version

Menu/Menu Map output

Engine Menu Map output (*3) (*3) (*3) − −
* 1. If the main power of MFP is shut down when a jam occurs, the counter is not updated.
* 2. It is not output to the Menu Map if the MFP is in the initial state. Switching the setting to enable outputting the data is possible by operating the system
maintenance menu.
* 3. The Engine Menu Map output is divided into the Engine Menu Print (first page) and the Engine EEPROM Dump Print (last page). However, the number of feed
papers to the respective trays is output (DUMP display) to the latter output only.
