Status Indicator RAPs
OF1 Audible Noise RAP
Use this RAP to isolate unusual noises in the machine.
NOTE: Due to the intermittent nature of unusual noises, this RAP can only give guidance on
how to isolate noises. This RAP will not find all possible causes. When machines become old
and worn, unusual noises may arise that are not covered in this RAP.
Procedure
1. Ask the customer if there are any specific machine functions that are noisy.
2. Ask the customer to demonstrate the function of the machine that generates the unusual
noise.
3. Check the Fault and Error logs.
4. Switch off the machine, GP 14. Wait for two minutes, switch on the machine and allow the
machine to perform a normal initialization and warm-up.
5. Run the machine in all modes. Also use the diagnostics to run individual components. Go
to the relevant subsection:
• Main drives and paper transport.
• DADH.
• ROS.
• Tray 1 and 2 Assembly.
• Tray 3 and 4 Assembly.
• Tray 5 Assembly
• Xerographics.
• Fuser.
• LCSS 1K.
• HCSS
• LCSS 2K.
• HCSS BM.
• Scanner.
• Network controller.
Main drives and paper transport
• Enter dC330 code 04-010 main drive motor, to run the main drives.
The following components will be run:
– Registration transport PL 8.15 Item 1.
– Developer module (32-55 ppm), PL 9.17 Item 2 or (65-87 ppm), PL 9.15 Item 2.
– Short paper path assembly PL 10.25 Item 1.
– Fuser module (32-55 ppm), PL 10.8 Item 1 or (65-87 ppm), PL 10.10 Item 1.
– Inverter post fuser and exit rolls and the jam clearance knob 3C rotate.
– To isolate the developer module:
Unlatch the xerographic module to separate the developer from the main drives. If
the source of the noise is the developer assembly, check the developer drive gear,
PL 9.15 Item 16.
– To isolate the fuser module:
Release the jam clearance latch 3b4a on the fuser module, to separate the pressure
roll from the fuser roll.
– Remove the fuser module to eliminate the noise caused by the fuser. If the source of
the noise is the fuser, go to the Fuser check out.
• Enter dC330 code 04-010 and add code 08-070 to energize the registration clutch. The
registration rolls and the jam clearance knob 4c rotate.
• Enter dC330 code 10-065 Vac. transport fan, to run the vacuum transport fan, PL 10.25.
• Enter dC330 code 08-060 motor slow or code 08-062 motor fast, to run the duplex trans-
port motor. The duplex transport rolls rotate, (32-55 ppm), PL 8.22 or (65-87 ppm), PL
8.20.
• Enter dC330 code 10-030 Invert Mot Fwd Slow, to rotate the nip split shaft, PL 10.11 Item
4.
• Enter dC330 code 10-035 Invert Mot Rev Slow, to rotate the nip split shaft and the jam
clearance knob 2b rotates, PL 10.11 Item 4.
• Enter dC330 code 10-040 Invert Mot Rev Duplex, to rotate the nip split shaft and the jam
clearance knob 2b rotates fast, PL 10.11 Item 4.
• Enter dC330 code 10-045 Invert Path solenoid, energizes the solenoid and moves the
inverter gate, PL 10.11 Item 14.
• Enter dC330 code 10-050 Invert Nip solenoid, energizes the solenoid and moves the nip
split shaft, PL 10.11 Item 4.
Possible causes and potential solutions are:
• Squeaks.
Possible causes are:
– Contamination of the drive shafts and the bearings.
– Bearings in cooling fans.
– Incorrectly adjusted or worn drive belts.
– Incorrectly aligned or damaged parts.
Solution:
– Clean the components.
– Remove and clean the drive shafts, bearings and then lubricate. Refer to ADJ 4.1
Machine Lubrication.
– Adjust the components if necessary.
– Check for parts that are damaged or out of position.
– Install new parts as necessary.
• Squeaks from the duplex tray (65-87 ppm)
Possible causes are:
– The metal stiffener bracket on the bottom of the duplex tray vibrates against the
plastic frame moulding.
Solution:
– Remove the duplex transport, REP 8.7.
– Remove the metal stiffener bracket and reform the securing edge with the two loca-
tion holes by 5 degrees. Refit the metal stiffener bracket and ensure that the metal
bracket is tight against the plastic frame moulding.
• Clicking.
Possible causes are:
– The waste toner auger clutch slipping. This clutch is designed to slip to prevent dam-
age to the auger gear box if toner backs up in the waste pipe.
