007-282 TRAY 2 LIFT UP FAILURE
Description
The TRAY 2 LEVEL SENSOR does not turn On
(block light) within the specified time after it has begun lifting
up.
BSD on : CH7.6 CH7.10B
Procedure
Install the TRAY 2. Run
DC330
[008-004] (Notes).
Does the TRAY 2 BOTTOM PLATE lift up?
Y
N
After running
DC330
[008-004] (Notes), is the TRAY 2
FEED/LIFTUP MOTOR going to revolve?
Y
N
Is +24 VDC measured between the TRAY 2 FEED/
LIFT UP MOTOR J827-3, 4 (+) and GND (-)?
Y
N
Check the +24 VDC circuit to the TRAY 2
FEED/LIFT UP MOTOR J827-3, 4 by referring
to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1)
(WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3)
(WN4.3.16 +24 VDC-4)
Turn Off the power. Check conductivity of the
following:
• Between the TRAY 2 FEED/LIFT UP MOTOR
J827-1 and TRAY MODULE PWB J547-6
• Between the TRAY 2 FEED/LIFT UP MOTOR
J827-2 and TRAY MODULE PWB J547-5
• Between the TRAY 2 FEED/LIFT UP MOTOR
J827-5 and TRAY MODULE PWB J547-2
• Between the TRAY 2 FEED/LIFT UP MOTOR
J827-6 and TRAY MODULE PWB J547-1
Is the resistance 1 Ohm or less for all wires?
Y
N
Check wires with more than 1 Ohm for an open
circuit or poor contact.
Replace the TRAY 2 FEED/LIFT UP MOTOR
(PL15.3/PL14.7) and TRAY MODULE PWB
(PL15.9/PL14.15) in sequence.
Check drive of the following:
• Manually turn the gear at rear of the TRAY 2 to check
that the BOTTOM PLATE moves up and down
smoothly.
• Gently push TRAY 2 in to check the drive
transmission is firmly engaged.
Run
DC330
[007-117]. Pull out the TRAY 2 and turn the
TRAY 2 LEVEL SENSOR On/Off.
Is the display switched between H and L?
Y
N
Repair the TRAY 2 LEVEL SENSOR using Generic
Permeable Sensor Failure FIP. (PL15.3/PL14.7)
Replace the following parts:
• TRAY MODULE PWB (PL15.9/PL14.15)
007-291 TRAY 3 LIFT UP FAILURE (TTM)
Description
The TRAY 3 LEVEL SENSOR does not turn On
(block light) within the specified time after it has begun lifting
up.
BSD on : CH7.7 CH7.10B
Procedure
Install the TRAY 3.
Run
DC330
[008-006] (Notes).
Does the TRAY 3 BOTTOM PLATE lift up?
Y
N
With
DC330
[008-006] (Notes) running
Is the TRAY 3 FEED/LIFTUP MOTOR going to revolve?
Y
N
Is +24 VDC measured between the TRAY 3 FEED/
LIFT UP MOTOR J828-3, 4 (+) and GND (-)?
Y
N
Check the +24 VDC circuit to the TRAY 3
FEED/LIFT UP MOTOR J828-3, 4 by referring
to Chapter 4 Wiring Data.
(WN4.3.13 +24 VDC-1)
(WN4.3.14 +24 VDC-2)
(WN4.3.15 +24 VDC-3)
(WN4.3.16 +24 VDC-4)
Turn Off the power.
Check conductivity of the following:
• Between the TRAY 3 FEED/LIFT UP MOTOR
J828-1 and TRAY MODULE PWB 549-B6
• Between the TRAY 3 FEED/LIFT UP MOTOR
J828-2 and TRAY MODULE PWB 549-B5
For the DC330 that have "Notes" in the following FIP,
check the machine status before selecting and
executing the appropriate DC330.
If the Diag with On signals is executed to the part that
is On, the communication link between the PSW and
the Main Unit may be broken.
In addition, the Diagnostics button indicated in
"Notes" is set to be executed after the Chain-Link No.
