2.7 Electrical Components
2.7.1 When Replacing the
ROM
on
Controller PCB or the
Reader Controller PCB
CLC5100 / CLC4000
The term "eader controller" or the "DC controller"
within parentheses indicates work unique to the
respective PCB.
1) Turn on the power switch.
2) Record the settings of the user mode. (reader
controller)
3) Set 'IMG REG' on the second page of the
INSTALLL screen under 'FUNC' in service mode
from '1' to '0'. (DC controller)
4) Turn off the power switch.
5) Disconnect the power plug from the power outlet.
(DC controller)
You must always disconnect the power plug from
the outlet; merely turning off the power switch will
not cut the power to the DC controller.
6) Replace the ROM of the DC controller and the
ROM of the reader controller.
7) Connect the power plug to the power outlet, and
turn on the power switch.
8) Execute 'FUNC > R CON > RAM CLR' in service
mode.
(the power switch will automatically be off)
[reader controller]
9) Turn on the power switch. (('E350' will be
indicated) (Rreader controller)
10) Execute 'FUNC > CCD > AUTO ADJ' in service
mode. (about 8 min; reader controller)
11) If a projector is installed, execute 'FUNC > PROJ
ADJ > PROJ CCD' in service mode. (reader
controller)
12) Compare the value in A of the service label and
2-26
the
DC
0002-5855
the service mode value; if different, or if you
replaced the DC controller PCB as a whole,
perform the steps for initializing the RAM on the
DC controller PCB shown below. (DC controller) If
you are not clearing the RAM of the DC controller
PCB, be sure to check the setting of the following:
'ADJUST>HV TR Y>TR #';
indicated, set it to '0'. (Be sure to do the same for
zones A, B, and C.)
13) Set 'IMG REG' on the panel of 'INSTALL2' under
'FUNC' in service mode from '0' to '1'. (DC
controller)
14) Enter new user mode settings and the value of B
of service label. (reader controller) (If any of the
service mode settings relating to the reader
controller other than the items under B of the
service label has been changed, be sure also to
change such settings.)
15) Turn off and on the power switch.
16) Execute auto gradation correction, after setting
'ADJUST > PASCA' in service mode to '1'.
2.7.2 When Replacing the
Reader Controller PCB
CLC5100 / CLC4000
1) Initialize the RAM on the reader controller PCB.
(See the appropriate instructions.)
2) Turn off and on the power switch.
2.7.3 When Replacing the
DC Controller PCB
CLC5100 / CLC4000
1) Start service mode, and check to make sure that
'DISP > BLT DRFT > BELT POS' is 'CENTER'; if
not, move the transfer belt to the center.
2) Turn off the power switch.
3) Disconnect the power plug from the power outlet.
then,
if
' 3'
is
