Introduction
Most Banknote Validator failures are due to minor
causes. Before replacing any parts, make sure that
all assembly and Circuit Board Connectors are
properly fitted and the Harnesses are properly con-
nected.
Faulty Banknote acceptance by the Validator por-
tion of the Unit is often caused when dust or Iron
powder adheres to the Identification Sensor, Mag-
netic Sensor or Transport Belt. Clean the Acceptor
section first, then observe the operating state of the
Validator in detail when re-initializing power. This
observation is important in locating any failure
causes and the possible fault area. If the Validator
Head has to be repaired by disassembling it,
always re-calibrate the Sensors following a repair.
Perform all repairs by referring to Calibration and
Testing in Section 6 of this manual, and Disassem-
bly/Reassembly in Section 4 of this manual.
Troubleshooting Overview
This product allows the operator to perform fault
diagnosis by checking various fault Table listings
against the symptom, and survey the cause(s) of
any failure occurrences during the process.
After determining the cause of the failure, execute
the Performance Test, perform a Sensor re-adjust-
ment and then repair the Unit by replacing any
appropriate parts deemed necessary.
Fault Table Listings
Table A-1 through Table A-3 each lists the various
possible Taiko fault conditions that can occur and
the necessary actions required to correct them.
Table A-6 lists the Red LED Color Flash Error
Code that may occur during normal and dynamic
testing operations.

Possible Fault Causes
Corrective Action Required
Banknote Acceptor is
not working
(does not accept any
Banknotes).
Power is not supplied to the
Acceptor
Verify that the specified Voltage and Ground Connections are supplied to
appropriate Pins of the Interface Connector.
Incorrect Connection
Verify that all Harnesses and Connectors are properly fitted.
Verify if any Connector Pins are bent, missing, or broken.
Verify if the specified Voltage is being supplied to the appropriate Pin
(See "Power Harness Wiring Procedure” on page 2-2 of Section 2 in this
Service Manual).
Correct Software is not
downloaded
Download the appropriate Software to the Taiko Unit (See "Software
Downloading Procedure” on page 6-1 of Section 6 in this Service
Manual).
CPU and/or Sensor Board
Failure
Perform the Acceptance Test (See "Performance Test Diagnostics” on
page 6-6 of Section 6 in this Service Manual). If the Acceptance Test
result is unacceptable, replace the CPU and/or Sensor Circuit Board
(See "CPU Circuit Board Removal"and "Sensor Circuit Board Removal”
on page 4-3 of Section 4 in this Service Manual). Once the CPU/Sensor
Board is replaced, perform a complete Calibration Procedure (See the
"Calibration Procedure” on page 6-5 of Section 6 in this Service
Manual).
The Entrance Sensor is not
working or there is a foreign
object lodged within the
entrance area
Remove ANY foreign objects in the Transport Path and clean the
Entrance Sensor (See "Cleaning Procedures” on page 2-6 in Section 2
of this Service Manual). Perform the Aging Test (See No.3 "Aging Test
Procedure” on page 6-6 in Section 6 of this Service Manual). If any
Sensor error is detected, replace the CPU/Sensor Board (See "CPU
Circuit Board Removal" in Section 4 of this Service Manual).
