Description: Generic Solenoid/Clutch Solenoids and electric Clutches are essentially electromagnets. Typically, a positive voltage is applied to one end of a coil, and a current driver is connected to the other end. Control Logic switches this driver to GND potential, actuating the magnet. Bi-directional solenoids have a bipolar driver connected to each end. One leg is switched to 24 VDC and the other to GND.
Troubleshooting Guides: Ensure that there is no damage or binding in the solenoid or in any mechanical linkage. If there is an Adjustment for the clutch or solenoid, make sure that the procedure was performed correctly
The Clutch/Solenoid is always energized. Y↓N→Enter Service Diagnostics Menu: Printer Menu > Troubleshooting > Service Tools > Printer Status Page >hold the Up and Down buttons simultaneously > Run Service Diagnostics > OK. Perform the Clutch or Solenoid tests. The Clutch or Solenoid energizes. Y↓N→There is +24 VDC between the switched leg (J543 pin A6 in the example, ) of the control PWB and GND. Y↓N→There is +24 VDC between the powered leg (J543 pin A7 in the example, ) of the control PWB and GND. Y↓N→Disconnect the connector (J543 in the example, ). There is +24 VDC between the powered leg of the control PWB and GND. Y↓N→Refer to the 24 VDC wirenets. check the input power to the control PWB. +24 VDC is present. Y↓N→Use the 24 VDC wirenets to troubleshoot the problem. Replace the control PWB. Check the wire in the powered leg of the circuit, (J543 pin A7 in the example, ) for a short circuit to GND (refer to Engine Control Board (MCU PWB) Plug/Jack Locations ). If the wire is OK, replace the clutch or solenoid. Disconnect the connector (J543 in the example, ). Check continuity through the two wires and the Clutch or Solenoid. There is less than 100 ohms between the two legs of the circuit. Y↓N→Disconnect the Clutch or Solenoid. Check continuity through the two wires and the Clutch or Solenoid. There is less than 100 ohms across the clutch or solenoid. Y↓N→Replace the Clutch or Solenoid. One of the two wires between the control PWB and the Clutch or Solenoid is open. Repair or replace the wiring as required. Replace the Control PWB. There is less than 1 VDC between the switched leg of the control PWB and GND. Y↓N→Replace the PWB. Replace the Clutch or Solenoid. The clutch or solenoid appears to be functioning correctly. Refer to the Circuit Diagram for the RAP that sent you here. Check the wires for loose connections or damage that may cause intermittent operation. Perform any required adjustments. There is a short circuit on the switched leg (J543 pin A6 in the example) from the solenoid or clutch. Check the wire for a short circuit to GND. If the wire is OK, replace the solenoid. If the problem persists, replace the controlling PWB.

Code: OF 99-6
Description: 2 Wire Motor Open
Troubleshooting Guides: There is +24 VDC measured between Pin 3(+) of the PWB and GND(-). Y↓N→There is +24 VDC measured between the Motor Pin 2(+) of the Motor and GND(-). Y↓N→There is +24 VDC measured between the Motor Pin 1(+) of the Motor and GND(-). Y↓N→There is +24 VDC measured between the PWB Pin 4(+) of the PWB and GND(- ). Y↓N→Replace the PWB. Check the wire between the PWB Pin 4 and the Motor Pin 1 for an open circuit or poor contact. Replace the motor. Check the wire between the PWB Pin 3 and the Motor Pin 2 for an open circuit or poor contact. Replace the PWB.

Code: OF 99-7
Description: 2 Wire Motor On
Troubleshooting Guides: Turn the printer power Off. Remove the PWB connector. There is 10 Ohm’s or less measured between the connector Pin 3 and the frame. Y↓N→Replace the PWB. Check the wire between the connector Pin 3 and the motor Pin 2 for a short circuit. If the check is OK, replace the motor.

Code: OF 99-8
Description: Set Gate Solenoid Open
Troubleshooting Guides: There is +24 VDC measured between the Nip/Release Solenoid Pin 1 (+) and GND (-). Y↓N→There is +24 VDC measured between the PWB Pin 5 (+) and GND(-). Y↓N→Check +24 VDC inputs on the PWB. If the check is OK, replace the PWB. Check the wire between the PWB Pin 5 and the Nip/Release Solenoid Pin 1 for an open circuit or poor contact. There is +24 VDC measured between the PWB Pin 4 (+) and GND(-). Y↓N→There is +24 VDC measured between the Nip/Release Solenoid Pin 3 (+) and GND (- ). Y↓N→Replace the Nip/Release Solenoid. Check the wire between the PWB Pin 4 and the Nip/Release Solenoid Pin 3 for an open circuit and poor contact. Follow the following when the release caused a problem. There is +24 VDC measured between the PWB Pin 6 (+) and GND(-). Y↓N→There is +24 VDC measured between the Nip/Release Solenoid Pin 2 (+) and GND (-) Y↓N→Replace the Nip/Release Solenoid. Check the wire between the PWB Pin 6 and the Nip/Release Solenoid Pin 2 for an open circuit or poor contact. Replace the PWB.

Code: OF 99-9
Description: Multiple Wire Motor For use on DC motors that: • have 1 or 2 DC power inputs • are controlled by 2 or more drivers • have no DC COM connections for return power • have no specific feedback circuits
Troubleshooting Guides: Connect black meter lead to ground. Measure voltage at each pin of J2 (example only, refer to the actual Circuit Diagram for the correct voltage and connector designation). +24 VDC is measured at each pin. Y↓N→Disconnect J2. Measure voltage at P2-1 and P2-6 (refer to HVPS, +24V LVPS T10 Plug/Jack Locations ). +24 VDC is measured. Y↓N→Turn the machine Off then On. Measure voltage at P2-1 and P2-6. +24 VDC is measured. Y↓N→If an interlock circuit is present, check the interlock circuit. Repair as required. If the interlock circuit is good, replace the PWB. Check the motor wires for a short circuit. If the wires are good, replace the Motor. Check the motor wires for obvious damage. If the wires are good, replace the Motor. Replace the PWB.

Xerox printer reset software introduction:

Notes before resetting Xerox printer:

– Identify accurate version, serial and crum of Xerox printer.
– How to get Xerox printer model info: Click Here
– Before you continue with the reprogramming of the firmware, please make sure that the device is installed on your computer.
– It is very important that under no circumstances should you remove the chip from the cartridge while reprogramming the firmware. After you have succesfully reprogrammed the printer, remove the chip from the cartridge and store it somewhere safely (the chip – a key). In all cartridges which you are going to use in the printer, the chip has to be either removed or sealed. If you have accidently inserted a new cartridge without removing the chip, the device will be blocked. In order to unblock it, you can use the stored chip as a key which help you to unblock the printer.
– And make sure that any other devices (except mouse and keyboard), which are connected to your computer via USB or LPT ports are disconnected. It’s preferable that the computer is connected to the “UPS” (uninterruptible power source) device, because if during the reprogramming process the electricity source has any interruptions, then the reprogramming will be carried out with an error, which makes the device unable to work.
– This firmware will be installed directly to your printer. Before opening firmare link make sure that printer is turned on and connected to your computer and printer drivers are installed correctly.
Be aware that with the reprogramming of the firmware the manufacturer’s warranty goes lost!!

How To Run Firmware Fix Xerox printer

1. Connect the printer to the computer and turn it on.
2. Wait until the printer is ready for work.
3. Drag and drop *.hd to usbprns2.exe file.

4. The reprogramming process starts automatically.
5. Wait until the printer reprograms (10-20 minute) and restarts.
6. After that the reprogramming process is finished, restart the printer.
