xerox 5016 code error U9

[tecnoacre]

Hello, friends, I have a xerox 5016 which is presenting the code U9, I wonder what this error is and how to solve the problem.

If this is the same as the 5018 then it is a pr belt hole issue and could be anything from a bad pr belt to a bad hvt power supply.

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.
YN
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.
YN
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.
YN
Measure the voltage between P406-1 ( P/J406) (+) on the AIOC PWB and ground (-).
The voltage is approximately +5VDC.
YN
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).
Completed

check these items and will back to inform the outcome, but thank the information ja

This issue is related to HVPS or Faulty print Cartridge .Try replacing old cartridge if u have it or with a new one.
