To remove lines on paper from a Sharp color copier, here are some maintenance tips:
Clean the Document Glass and Automatic Document Feeder (ADF)
Clean the Document Glass: Open the ADF and use a soft cloth to clean the document glass. If necessary, slightly moisten the cloth with water or a small amount of neutral detergent. Wipe with a dry cloth afterwards.
Clean the Scanning Area: If the lines persist, clean the scanning area, which is the thin long glass near the document glass. Use the glass cleaner stored in the ADF. Make sure to replace the cleaner after use .
Clean the Main Charger of the Photoconductive Drum
Access the Charger Cleaner: Open the front cover and remove the waste toner box. The charger cleaner is attached to the front cover.
Clean the Main Charger: Use the charger cleaner to clean the main charger that charges the photoconductive drum .
These steps should help you remove lines on the paper. If the issue persists, consider contacting a professional technician for more in-depth servicing.
