5-4 Note for replacing Main board
When you replace the main board to new one, the
information 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 cartridge 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
cartridge 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.)
2. Replace Main board.
