5-5 Note for replacing Main board
When you replace the main board to new one, the informa-
tion on the toner state is cleared. Therefore, you should
update the information to the new board by entering the
exact value of total toner count and specifying the toner car-
tridge installed currently is shipped with the machine or new.
If not, 'TONER LOW/EMPTY' message may not appear
when the toner is run out.
1. In Tech mode, print 'SYSTEM DATA LIST'. The list
includes the total toner count and CRU state information.
• TOTAL TONER COUNT: The total number of the dots
used to print up to current time.
• CRU STATE: The page number which the toner car-
tridge can print. (The yield of a new toner cartridge is
approximately 2,500 pages and that of the cartridge
supplied with the machine is approximately 1.000
pages.)
