Formatter Board Failure

This error indicates a problem with the formatter board, which is the main logic board of the printer. It controls all printer functions and communication.

Formatter Board Failure

This error indicates a problem with the formatter board, which is the main control unit of the printer. It often suggests a hardware malfunction that prevents the printer from booting or operating correctly.

System Error: Main PCA Malfunction

This error indicates a problem with the printer's main board (PCA - Printed Circuit Assembly). It's a critical hardware failure that prevents the printer from operating.

Carriage Assembly Failure

This error indicates a problem with the carriage assembly, which holds the printheads and moves across the paper. It suggests the carriage motor, encoder strip, or belt might be faulty, preventing proper movement.

Power Supply Unit (PSU) Failure

This error indicates a problem with the printer's power supply unit. The PSU is responsible for converting wall power into the various voltages needed by the printer's components.

Printhead Voltage Error

This error indicates an issue with the voltage supplied to the printheads. Incorrect voltage can damage printheads or prevent them from firing properly.

Ink System Calibration Failure

This error indicates that the printer failed to successfully complete an ink system calibration. This can lead to inaccurate color reproduction or print quality issues.

Ink System Valve Failure

This error indicates a problem with one of the ink system valves, which control the flow of ink. A faulty valve can cause ink flow issues or leaks.

Internal Heater Failure

This error indicates a problem with an internal heater element, such as a pre-heater or post-heater. These heaters are crucial for preparing media and drying ink.

Service Error: Internal Communication Error

This error indicates a general problem with internal communication between the printer's components. This prevents the printer from functioning.

Service Error: Internal Sensor Failure (Unspecified)

This error indicates a problem with an unspecified internal sensor. The printer may not be able to perform certain functions accurately.

Carriage Axis Motor Failure

This error indicates a problem with the motor responsible for moving the printhead carriage across the printer. It will prevent any printing operations.

Paper Handling Error: Take-up Reel Motor Malfunction

This error indicates a problem with the take-up reel motor, which winds printed paper onto a roll. The printer cannot collect printed output.

Calibration Error: Scan Axis Calibration Failure

This error indicates a problem during the scan axis (carriage movement) calibration. The printer cannot accurately position the printheads.

Starwheel Motor Failure

This error indicates a problem with the starwheel assembly motor, which raises and lowers the starwheels that help guide the media after printing. It might be jammed or faulty.
