Every month the printer feeder wheel area behind the front fan on the printhead should be cleared from debris. This is easily done, as the front fan simply flips open by rotating around its bottom right corner. Use the brushes from your Maintenance Kit to remove any excess filament build up. Please be certain to put the fan back in place once you have finished!

Every three months a check of whether the printer is noisier during printhead or Z screw movement should be done. If so, add a small amount of grease to the movement rods or Z screw, type NSK LR3 or similar.
