Item Explanation
CLEAR EVENT LOG This item allows the service representative to clear the printer internal error log.
TOTAL PAGE COUNT The page count stored in NVRAM and displayed on the configuration page printout represents
the number of pages, which the formatter has formatted (engine test prints are not included in
this number). If it becomes necessary to repair a printer by installing a new controller PCA, the
service representative must be able to set the page count so that it represents the age of the
print engine rather the age of the controller PCA.
MAINTENANCE COUNT This item allows a service representative to reset the page count if the value is lost for some
reason. This will be set initially at the factory to 0. Users can enter any number up to value set
for maintenance interval. This value will be reset to 0 if the user sets the menu item
NEW
MAINTENANCE KIT to YES in the Resets menu.
MAINTENANCE INTERVAL This item allows a service representative to set the page count threshold when the next
service is due for the printer. Initially, this will be set at the factory to a value applicable to
each type of engine. Users can enter any number up to 350,000.
SERIAL NUMBER This item allows the manufacturing facility to set the serial number of the formatter initially
installed in the printer. Also, this number is updated accordingly if a service representative
replaced a printer formatter board.
COLD RESET PAPER The default paper size is stored in NVRAM, and when the printer is cold reset, the default
paper size is set to the factory setting.
