10-399 Fuser Authorization Failure RAP
10-399 The fuser CRUM failed the authorization check.
The authorization check is performed to ensure that the fuser installed in the system is compat-
ible with the machine configuration: 50Hz or 60Hz.
Procedure
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP 14. Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
Do not touch the fuser while it is hot.
Install a new Fuser module that matches the machine configuration.

death or injury. Moving parts can cause injury.
Do not touch the fuser while it is hot.
• Check the fuser web motor drive coupling,
• Check the fuser drawer connector,
Procedure
NOTE: The door interlock switch must be cheated when checking +24V components.
The web motor does not run continuously. It is pulsed on for multiples of 0.9 seconds duration.
The pulsing of the motor is felt or heard during the print mode.
Enter dC330 code 10-010 fuser web motor, MOT10-010. The movement is very slow (approxi-
mately 0.1 rev per minute). The motor runs.

Go to Flag 1. Check MOT10-010. Refer to:
• Figure 1.
• GP 10 How to Check a Motor.
• P/J154, Main Drives PWB.
• 01G +24V Distribution RAP.
• 01B 0V Distribution RAP.
Install new components as necessary:
• Fuser web motor assembly, (35-55 ppm)
• Fuser web motor assembly, (65-90 ppm)
• Main drives module, (35-55 ppm)
• Main drives module, (65-90 ppm)
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed,

Check the following:
• Drive coupling on the fuser web motor shaft, (65-90 ppm)
• Drive coupling on the fuser web motor shaft, (35-55 ppm)
• Drive coupling on the web assembly,
The life expectancy of the fuser web is the same as the Fuser module. Install new Fuser mod-
ule, (35-55 ppm) PL 10.8 Item 1, (65-90 ppm)
