'''Additional maintenance performed:'''

'''Used PTFE coupler'''

The picture below shows the state of the PTFE coupler when initially replaced. The printer had been repeatedly jamming on initial filament feeding and not printing well. Both PTFE coupler and Nozzle were replaced. They had been used for 425 printing hours.
