00 00 1. Pre-imprinter Door is not closed
enough.
2. Pre-imprinter Door Detector does
not work correctly.
00 00 Access error to SDRAM (IC2018,
IC2019, IC2020, IC2021) on the
INTERFACE Board
00 00 Access error to an additional
SDRAM attached to CN2007
00 00 Access error to Analogue IC
1. Shut the door properly.
1. Check the tip inside the Pre-imprinter
Door interrupts the detector when closing
the door.
2. Execute Key / Sensor in Sec.9.3.6 to
check the detector status.
3. Check the following connection and
soldering condition on each connector.
a. CN5022 (RELAY (UPPER) Board) to
CN1014 (CONTROL Board)
4. Check the following parts' soldering
condition to repair it.
a. RELAY (UPPER) Board
→ Q5019, IC5014, R5052, R5054
b. CONTROL Board
→ IC1035, Z1064, Z1070
5. Check the following signals on the RELAY
(UPPER) Board and CONTROL Board.
a. CN5022-7
→ 0 V (when opening the
Pre-imprinter Door)
6. Replace faulty parts or boards.
1. Check the soldering condition of the Gate
Array (IC2047) on the INTERFACE Board
to repair it.
2. Check the soldering condition of the
SDRAM (IC2018, IC2019, IC2020,
IC2021) on the INTERFACE Board to
repair it.
3. Replace faulty parts or INTERFACE
Board.
1. Check whether the additional SDRAM is
attached to CN2007, properly. Or re-
attach it.
2. Check the SDRAM is one of the
memories recommended by PCC.
3. Check the soldering condition of the Gate
Array (IC2047) and its surrounding circuit
on the INTERFACE Board to repair it.
4. Check the soldering condition of the
CN2007 (for the SDRAM) and its
surrounding circuit on the INTERFACE
Board to repair it.
5. Replace faulty parts or INTERFACE
Board.
1. Check the soldering condition of the
IC1010 to IC1013 and its surrounding
circuit on the CONTROL Board to repair
it.
2. Check the soldering condition of the
IC1024 and its surrounding circuit on the
CONTROL Board to repair it.
3. Replace the CONTROL Board.
