If you are replacing the main controller PCB, be sure to transfer the
following components from the old to new PCB:
[1]Å@boot ROM
[2]Å@HDD
[3]Å@image memory (SDRAM)
[4]Å@counter memory PCB
0007-8275
If the user uses NetSpot Accountant (NSA) in Combination with a Card
Reader
The SDRAM of the main controller retains card ID used by NSA. If you have
replaced the main controller, you will have to download the card data from
NSA once again to permit NSA to perform statistical operations.
If you have formatted the HDD and downloaded the system software, you
will have to go through a specific set of steps:
1) Format the HDD.
2) Download the system software.
3) Make the following selections:
Å@COPIER>FUNCTION>INSTALL>CARD.
4) Enter a card No.
Å@Enter the first of the numbers that will be used for group control, and
0007-4922
press the OK key (e.g., if you are planning to use cards from No. 1 thorough
No. 100, enter '1').
5) turn off and then on the main power.
6) Check the count control mechanism in user mode.
Å@system control setup>group ID control>count control
check to see as many as 'ID00000001 through ID00001000' have been pre-
pared.
7) Set the IP address in user mode.
Å@system control setup>network setup>TCP/IP setup>IP address
Set 'IP address', 'gateway address', and 'sub net mask'.
8) Enter a number of your choice in user mode.
Å@system administrator info setup>system control group ID>system con-
trol ID No.
9) Hold down the control panel power switch for 3 sec or more.
10) Go through the instructions on the control panel for shut-down sequence
so that the main power switch may be turned off.
11) Turn off the main power switch. Wait for 3 sec or more, and turn it back

Unless you have registered 'system control group ID' and 'system control
ID No.', you will not be able to register cards for the device in the course of
Net Spot Accountant setup work.
12) Download the card ID.
Å@Keep the machine in a standby state < and download the card ID to be
used from the NSA>
13) Check the count control particulars in user mode.
Å@system control setup>group ID control>count control
See that only the downloaded ID data is shown.
14) Check to see that the operation is normal.
Make copies using a user card that has been registered using the NSA, and
check to see that the count of the card in question has been incremented cor-
rectly.
