Troubleshooting 6.7.2 IMAGE QUALITY PROBLEM problem Cause/Solution The polygon mirror of the laser unit is dirty. Adjust the image density. Paper is damp. Use paper that has been stored properly. If you enable [Toner Saving], printing is generally less dense.
Energy Save 7. ENERGY SAVE 7.1 ENERGY SAVE 7.1.1 ENERGY SAVER MODES Customers should use energy saver modes properly, to save energy and protect the environment. The backlight of the screen is turned off and "Energy Saver Mode1" appears on the screen, and then the fusing lamp is turned off and "Energy Saver Mode2"...
Energy Save Return to Stand-by Mode Energy Saver Mode 1 Recovery time: 10 sec. Energy Saver Mode 2 Recovery time: 20 sec. Recommendation We recommend that the default settings should be kept. If the customer requests that these settings should be changed, please explain that their energy costs could increase, and that they should consider the effects on the environment of extra energy use.
Paper Save 7.2 PAPER SAVE 7.2.1 EFFECTIVENESS OF DUPLEX/COMBINE FUNCTION Duplexing and the combine functions reduce the amount of paper used. This means that less energy overall is used for paper production, which improves the environment. 1. Duplex: Reduce paper volume in half! 2.
Paper Save Duplex + Combine: Using both features together can further reduce paper volume by 3/4! To check the paper consumption, look at the total counter and the duplex counter. The total counter counts all pages printed. For one duplex page, the total counter goes up by 2. ...
