How to use

Power off the printer and disconnect it from the mains before beginning work. Remove any paper or ribbons that obstruct access to the existing cover, then release the retaining clips or screws securing the old cover and lift it away.

Reinstall any removed consumables and reconnect power. Perform a test print to confirm correct alignment and that the cover does not interfere with printhead movement.

Recommendations

Handle the transparent cover by its edges to avoid fingerprints on viewing areas. Use only manufacturer-recommended parts for repairs to maintain printer reliability. Inspect the cover periodically for cracks or deformation and replace it if damaged to prevent dust accumulation and potential print defects.
