This error indicates that the printer failed its initial power-on self-test. A critical component is not functioning, preventing the printer from booting.

Service Error: Watchdog Timer Reset

This error indicates that the printer's internal watchdog timer has reset the system due to an unrecoverable software or hardware fault. The printer has crashed.

Ink System Error: Trailing Cable Malfunction

This error indicates a problem with the trailing cable that connects the carriage assembly to the main PCA. This cable transmits data and power to the printheads.

Starwheel Motor Failure

This error indicates a problem with the starwheel motor assembly, which helps to flatten and guide the paper after printing. A malfunction can cause paper jams or printing issues.

Paper Handling Error: Paper Jam

This error indicates that paper is jammed within the printer's paper path. The printer cannot continue printing until the jam is cleared.
