• Check the printer
◦
The scanner lid might not be closed correctly.
◦ The scanner glass or lid backing might need cleaning. For more information,
see Maintain the printer.

information, see Maintain the printer.

resolve poor quality copy problems. For more information, see Print quality
troubleshooting.
