If the printed surface is scratched or stained on plain paper, it may also help to set the paper thickness lever to the Down position. Check 3 ARE YOU PRINTING ON CURLED PLAIN PAPER? If curled plain paper is loaded with the curl bowing up, the print heads may scratch the bottom edge of the paper. Try to uncurl the paper. If necessary, turn the paper over, and load it in the sheet feeder again. Troubleshooting 322
