Status Indicator RAPs
06-020 ROS Motor Failure RAP
06-020. This fault code has two failure modes.
1. The ROS motor ready signal was not received by the IOT PWB within the set time of the
ROS being powered on.
2. The IOT PWB recognizes a change of state of the ROS motor ready signal during opera-
tion.
Initial Actions
• Check that the harness connector at PJ2 on the IOT PWB is fully inserted.
Procedure
WARNING
Avoid exposure to laser beam. Invisible laser radiation.
Switch off the machine, then switch on the machine, GP 14. The 06-020 fault still exists.

Perform SCP 6 Final Actions.
Enter the dC330 output code 06-020 and listen for the ROS motor. The ROS motor gives a
distinctive ascending frequency sound, of a short duration (5 to 6 seconds) during tran-
sition from standby to run.

N
The xerographic module is fully home and the front door is fully closed or the front
door interlock is cheated.

Correct the condition. If necessary go to the 01-300 Front Door Open RAP.
Go to Flag 1. Check the following voltages at P/J18 on the LVPS:
• +24V between pins 1 and 2.
• +3.3V between pins 3 and 4.
The voltages are good.
Y N
Go to the relevant RAP:
• 01B 0V Distribution RAP, refer to the 3.3V return and 24V return.
• 01D +3.3V Distribution RAP.
• 01G +24V Distribution RAP.
Enter the dC330 output code 06-020 to run the ROS motor. Go to Flag 2. 0V is avail-
able at P/J2 pin 1 on the IOT PWB.
Y
N
Disconnect P/J2. Go to Flag 3. 0V is available at P/J2 pin 6 on the IOT PWB.

Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed,
PL 1.10 Item 2.
NOTE: The ROS must be removed from the machine, REP 6.1, to disconnect P/
J120 and P/J121. The ROS PWB where P/J120 and P/J121 are connected may
not be marked with the correct PJ numbers. P/J120 can be identified as a four way
power harness. P/J121 can be identified as a seven way signal harness.
Go to Flag 1, Flag 2 and Flag 3. Disconnect P/J120 and P/J121 and check the wir-
ing. The wiring is good.
Y
N
Repair the wiring.
Install a new ROS, PL 6.10 Item 4.
Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL 1.10 Item
2.
Go to Flag 2. 0V is available at P/J2 pin 1.
Y

NOTE: The ROS must be removed from the machine, REP 6.1, to disconnect P/J120
and P/J121. The ROS PWB where P/J120 and P/J121 are connected may not be
marked with the correct PJ numbers. P/J120 can be identified as a four way power har-
ness. P/J121 can be identified as a seven way signal harness.
Check the continuity of the seven way signal harness between P/J2 and P/J121. The
harness is good.
Y
N
Install a new ROS power distribution/communication harness, PL 6.10 Item 5.
Install a new ROS, PL 6.10 Item 4.
If the fault condition persists, perform the following:
• Check the condition of the associated wiring and connectors. Repair the wiring or install
new components as necessary.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL 1.10 Item
2.
• Install a new ROS, PL 6.10 Item 4.
