SERVICE RAM ADDRESSES
49FB64 to 49FB77(H) - SC codes NOT for automatic service call
If the fax unit receives an SC code from the copier engine other than programmed in these
addresses, the fax unit sends an automatic service call report to the programmed service
station.
Six SC codes have already been programmed at default, as shown in the table below. Four
more SC codes can be programmed, if required (If an address contains FF(H), a code is not
programmed in it).
Program an SC code in four-digit BCD format as shown in the example below.
Example: SC code '192'
