7.4.26 Mechanical Noise
You were directed to this RAP to diagnose and repair an audible mechanical noise coming from within
the printer. Please be aware that electrical arcing may also generate an audible noise, especially in the
areas of the High Voltage Power Supply and the line voltage.
1 The noise is present in the standby mode.
Y: Power OFF the printer and perform the following checks. Repair/replace any faulty
component:
• Inspect the Fan Assembly and any associated wire harness.
• Inspect the Laser Assembly.
• Inspect/remove the Hard Drive Assembly mounted on the System Controller. After
removal, test again in the standby mode to determine if the Hard Drive is the source of
the noise.
N: Go to step 2.
2 Execute Diagnostic Mode 1, Main Motor. The noise is present.
Y: Go to step 3.
N: Go to step 5.
3 Open the Front Cover Assembly and remove the EP Cartridge. Remember to bypass the
interlocks for the Front Cover Assembly and the EP Cartridge. Perform Diagnostic Mode 1, Main
Motor and inspect the drive train gears for broken or missing teeth. The noise is present.
Y: Go to step 4.
N: Inspect the Front Cover Assembly for loose, broken, or misaligned parts. Replace the EP
Cartridge if necessary.
4 Open the Rear Cover, remove the Fuser Assembly, and bypass the Rear Cover interlock. While
performing Diagnostic Mode 1, Main Motor, inspect the drive train gears from the rear of the
printer for broken or missing teeth. The noise is present.
Y: Carefully inspect/repair the Paper Handling Unit for the source of the noise before
replacing the Main Motor Assembly.
N: Replace the Fuser Assembly.
5 Perform Diagnostic Mode 1 (Exit Motor CW and CCW respectively). The noise is present.
Y: Determine the exit component causing the noise and replace.
N: Go to step 6.
6 Power OFF the printer. Remove all the interlock bypasses in steps 3 and 4, and install the EP
Cartridge. Remove all input and output options, and the Hard Disk from the System Controller.
Close the Front and Rear Cover Assemblies. Power ON the printer, and from Diagnostic Mode 2
(Test Print Mode), run a Print Engine Controller Test Print. The noise is present.
Y: Inspect the Tray 1 Feed Roll drive components and replace as necessary.
N: Go to step 7.
