5.3.3 Diag. Test

5.3.3.1

Actuator

It is possible to operate each motor individually and to check for
motor defects and to check the operation of the mechanisms.
When cleaning roller has not been inserted or a door open, the
power supply to the motor is cut, it will not operate, and inspec-
tion should be performed.

(1) Ink TUP Enc. (Ink Take-Up Encoder)

Before starting the test, remove the ink cassette. The en-
coder that detects the amount of ink ribbon feed is
checked. An error is displayed if there are any abnormali-
ties.

(2) Ink TUP Mo. (Ink Take-Up Motor)

Before starting the test, remove the ink cassette. The ink
take-up motor operates for about 5 seconds.

(3) Ink SPY Mo. (Ink Supply Motor)

Before starting the test, remove the ink cassette. The ink
supply motor operates for about 5 seconds.

(4) Film TUP Mo. (Re-Transfer Film Take-Up Motor)

Before starting the test, remove the re-transfer film cas-
sette. The re-transfer film take-up motor operates for about
5 seconds.

(5) Film SPY Mo. (Re-Transfer Film Supply Motor)

Before starting the test, remove the re-transfer film cas-
sette. The re-transfer film supply motor operates for about
5 seconds.

(6) Card Feed Mo. (Card Feed Motor)

The card feed motor operates for about 5 seconds, and the
roller rotates.

(7) Turn Over Mo. (Turn Over Motor)

The turn over motor rotates, and the turn over unit rotates
once. (Two half turns)

(8) Turn Feed Mo. (Turn Over Feed Motor)

The turn over feed motor operates, and the inside roller of
the turn over unit rotates for about 5 seconds.

(9) Card Load Mo. (Card Load Motor)

The card load motor rotates for about 5 seconds.

(10) Cam Mo-Platen (Heater Cam Motor - Platen)

The heater cam motor rotates, keeps pressing the platen
for about 3 seconds, leaves the platen, then goes back to
the standby position.

(11) Cam Mo-HR (Heater Cam Motor - Heat Roller)

The heater cam motor rotates, keeps pressing the heat roll-
er for about 3 seconds, leaves the heat roller, then goes
back to the standby position.

5.3.3.2

Sensor

Correct operation of the sensor is checked. Confirm the valve is
changed, when the sensor is interrupted or reflected.

5.3.3.3

Memory

The picture memory SDRAM on the Main PWB is tested. The
buzzer sounds in case of an error. The error LED also will light.

5.3.3.4

Display

All the dots of LCD are displayed black. Confirm that there is no
missing dot.

5.3.3.5

Back Color

The back colors red, green, and blue are displayed for 3 seconds
and correct display of the back colors is tested.

5.3.3.6

Registers

This printer has four temperature-detecting thermistors:

(1) Retransfer heat roller thermistor
(2) Bend remedial heat roller thermistor
(3) Thermal head thermistor
(4) Ambient temperature thermistor

These thermistors output analog signals, which are applied to the
circuits for four channel 8bit A/D converter IC.
Each of these converted value in a hex decimal number as
shown below. Note that the following values are the values at the
moment the [

] button is pressed.
