HP Color LaserJet CM1415fnw error 59.9: ITB motor failure

The HP Color LaserJet CM1415fnw error 59.9 is an alert for a failure in the motor of the Intermediate Transfer Belt (ITB) unit. When the printer attempts to start this assembly but detects excessive resistance or a missing speed signal, it halts with this error. This component is vital for color alignment in laser printing.

Common causes

  • 1ITB unit bearing wear.
  • 2Residual toner accumulation blocking the gear system.
  • 3Belt speed sensor (flag) failure.
  • 4Belt misalignment on the rollers.

Solutions

Quick Diagnosis

Code 59.9 is a mechanical rotation problem. If the ITB (the large assembly under the toners) has rigid rotation or if you notice dirty side gears, that is likely the cause. It is common for the ITB's internal grease to dry out after years of use.

Step-by-Step Fix

  1. ITB Removal: Open the front door and pull out the toner drawer; underneath you will find the ITB, remove it following the manual.
  2. Rotation check: Try turning the ITB rollers manually with gentle force. If constant resistance is felt, the unit is jammed.
  3. Contact cleaning: Clean sensors and connectors on the right side of the ITB.
  4. Retry: Insert again and power on; if the ITB cannot spin upon startup, the internal mechanism has failed.

Prevention and Maintenance

Do not force the ITB assembly extraction, as electrical connectors are fragile. Keeping the printer's interior free of toner residue is the best way to ensure the transfer mechanism does not seize up.

When to Call a Technician

Replacing the ITB assembly is an advanced-level task. If cleaning steps do not resolve it, the unit has reached its end of life and needs to be replaced with a new part to restore operation.

    Reinstall the ITB, ensuring it clicks correctly into the rails.

Frequently asked questions

This error points to a problem in the rotation mechanism of the Intermediate Transfer Belt (ITB) unit.

If the ITB is internally damaged, replacing the entire unit is necessary and can be costly.

Usually due to bearing wear in the ITB or hardened residual toner.

No, if the belt does not spin, printing cannot occur and it may damage the main motor.
