System Error: Carriage PCA Malfunction
This error indicates a problem with the carriage assembly's printed circuit board. This board controls the printheads and their communication with the main PCA.
- 1Faulty Carriage PCA (Printed Circuit Assembly) itself, leading to incorrect signal processing or power delivery to printheads.
- 2Damaged or worn Flexible Flat Cable (FFC) connecting the Carriage PCA to the main PCA, causing intermittent or complete loss of communication.
- 3One or more defective printheads drawing excessive current or shorting, which can overload or damage the Carriage PCA's circuitry.
- 4Contamination (e.g., ink, dust) on the Carriage PCA's connectors or components, interfering with electrical contacts.
- 5Damage to the carriage assembly's electrical contacts that interface with the printheads, preventing proper communication or power supply.
- Printer displays "02.0 System Error: Carriage PCA Malfunction" on the front panel.
- Printheads are not detected or appear to be missing, even when correctly installed.
- Printer fails to initialize or move the carriage assembly during startup or printing.
- Intermittent or complete loss of communication with one or more printheads, leading to blank prints or missing colors.
- Unusual noises from the carriage assembly, such as grinding or clicking, sometimes preceding the error.

The component that deposits ink onto the media. DesignJet printers use thermal inkjet printheads that fire tiny droplets of ink through microscopic nozzles.
The mechanism that moves the printheads back and forth across the media during printing. It rides on a guide rail and is driven by the scan-axis motor via a belt.
The main logic board inside an HP DesignJet printer that controls all operations, including processing print jobs, managing ink delivery, and communicating with connected devices.
The built-in blade mechanism that automatically cuts media after each print job or at specified intervals.
A calibration process that ensures all printheads are precisely aligned relative to each other for accurate color registration and sharp output.
When the printhead physically contacts the media surface during printing, potentially damaging both the print and the printhead.
