DesignJet T770

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.

System Error: Hard Disk Drive (HDD) Malfunction

This error indicates a problem with the printer's internal hard disk drive. The HDD is used for job storage, processing, and firmware functions.

Printhead Missing/Not Installed

This error indicates that a printhead is either missing from its slot or was not properly installed. The printer cannot detect the presence of a printhead.

Ink Supply Station Failure

This error indicates a general failure of the Ink Supply Station (ISS), which manages ink delivery from cartridges to printheads. It could be a pump, sensor, or valve issue.

Ink Maintenance Cartridge Full/Missing

This error indicates that the ink maintenance cartridge (waste ink tank) is full or missing. The printer cannot operate until it is replaced or properly installed.

Ink System Priming Failure

This error occurs when the printer fails to successfully prime the ink system, meaning it cannot draw ink from the cartridges to the printheads. This prevents printing.

Ink System General Error

This is a general error indicating an unspecified problem within the ink delivery system. It suggests a component is not functioning as expected, preventing proper ink management.

Carriage Error: Carriage System Failure

This is a general critical error indicating a failure within the entire carriage system. The carriage cannot move or operate correctly.

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: EEPROM Configuration Error

This error indicates a problem with the printer's non-volatile memory (EEPROM) where configuration data is stored. This can lead to incorrect settings or boot failures.

Service Error: Component Initialization Failure

This error indicates that a specific internal component failed to initialize during startup. The printer cannot function correctly.

Ink System Error: Printhead not detected or faulty

This error means the printer cannot detect one or more printheads, or a detected printhead is faulty. This prevents printing.

Carriage Error: Encoder Strip Malfunction

This error indicates a problem with the encoder strip, a clear plastic strip that tells the carriage its position. If dirty or damaged, the printer cannot track carriage movement 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.
