Hi friends

This machine sometimes pop-up error U2. Subcode is 1. After power off/on it works.

Any ideas how to solve this problem?

Thanks

U2-1 Carriage Module Fail

BSD-Reference:CH6.2 (Figure 2)

Explanation

A carriage fault was detected.
Procedure
Execute diagnostics [05-22 Move scanner to home position] and [05-23 Move scanner to maintenance position]. (How to Enter the Diagnostic Mode)
The carriage moves.
YN
Check each IIT Carriage connector.
Each connector is connected securely.
YN
Connect each connector securely.
Check for foreign substances and deformed parts in the carriage.
None is found.
YN
Remove the foreign substances and repair the deformed parts.
Replace the IIT Carriage (PL 10.3)(REP 10.3.1).
Execute diagnostics [05-23 Move scanner to maintenance position]. When the IIT Carriage has moved to the leftmost position, press the [Stop] button to put the Carriage Sensor into the blocked state.
Execute diagnostics [5-11 Home Sensor], and "H" is displayed.
YN
Check each IIT Carriage and Carriage Sensor connector.
Each connector is connected securely.
YN
Connect each connector securely.
Replace the Carriage Sensor (PL 10.6) and the IIT Carriage (PL 10.3) (REP 10.3.1) in that order.
Check the Carriage Sensor (PL 10.6 ).
The Carriage Sensor is installed properly.
YN
Install the Carriage Sensor (PL 10.6) properly.

Thank you very much my friend.
After this code i got U9, don't know subcode. Paper stops on drum. After cleaning transfer corona, everything seems to work fine.
Could you list U9 codes, just curious what it means?

hope this will help!


U9-0 HVPS Fail

BSD-Reference:

CH9.1 (Figure 1)

Explanation

A 500 ms cycle of HVPS#ERR=High was detected twice in a row.

Procedure

Close the Left Hand Cover and the Front Cover. Make sure that the Drum Cartridge and the
Transfer Corotron are properly seated. Measure the voltages between P406-2 (

P/J406) (+)/
P406-4(+)/P406-5(+) on the AIOC PWB and ground (-). The voltages are approximately
+5VDC.
Y N

Replace the AIOC PWB (

PL 8.1) (REP 8.1.1) and the HVPS (PL 8.2) (REP 8.2.1) in that
order.
Execute diagnostics [09-04 HVPS ON (Low Voltage)]. (How to Enter the Diagnostic Mode)

The voltages at P406-2 (

P/J406) (+)/P406-4 (+)/P406-5 (+) become 0.
Y N

Replace the AIOC PWB (

PL 8.1) (REP 8.1.1).
Replace the HVPS (PL 8.2) (REP 8.2.1). The problem is solved.
Y N

Measure the voltage between P406-1 (

P/J406) (+) on the AIOC PWB and ground (-).

The voltage is approximately +5VDC.
Y N

Check between J520-1 (

P/J520) and J406-1 ( P/J406) on the HVPS PWB for a
short circuit.
If there is no short, replace the HVPS (PL 8.2) (REP 8.2.1).
Replace the AIOC PWB (PL 8.1) (REP 8.1.1).
