Why do the printed pages have a gray background?

Description of Solution 200000002403

Check the following:

1. Make sure you use paper that meets the recommended specifications.

2. The drum unit may be damaged. Try wiping the Green (or Dark brown) image drum (roller) with a soft cloth. If the problem

persists then replace the DR-600 drum unit.

3. The toner cartridge may be damaged. Replace it with a new TN-670 toner cartridge.

4. Check the printer's environment - high temperatures and high humiditycan increase the amount of background shading.
