What This Error Means

This error indicates a problem with the vacuum fan, which helps hold the media flat during printing. This can lead to print quality issues or paper jams.

Common Causes
  • 1Vacuum fan motor failure or bearing seizure, preventing rotation.
  • 2Damaged or disconnected vacuum fan electrical cable or connector, leading to loss of power.
  • 3Faulty vacuum fan driver circuit on the main PCA (Printer Control Assembly) unable to supply correct voltage or control signal.
  • 4Accumulation of dust, debris, or paper particles obstructing the vacuum fan blades or intake vents, reducing airflow.
  • 5Vacuum fan sensor malfunction, providing incorrect feedback to the printer's control system, even if the fan is physically working.
Symptoms to Watch For
  • Error code 56:10 displayed on the front panel, immediately halting printing operations.
  • Media lifting or buckling during printing, especially with lightweight or thin paper, leading to head strikes or smudging.
  • Frequent paper jams, particularly as media feeds through the print zone, due to improper media hold-down.
  • Audible absence of the typical vacuum fan noise during printing preparation or operation.
  • Reduced print quality, such as banding or uneven ink application, caused by inconsistent media flatness.
Basic Troubleshooting Steps
1. Turn off the printer and unplug it. 2. Ensure the printer has adequate ventilation. 3. Inspect the vacuum fan vents for dust or obstructions. 4. Plug in and restart the printer. If the fan is faulty, it needs replacement.
