Please remember that print yield will be different based on how the machine is used:
• The rate of toner consumption is much faster with documents that consistently contain photos or
charts that require large areas of fill. The AIO will run out of toner much sooner.
• The rate of toner consumption is slower with documents that contain mostly text and an only a
moderate number of photos or other images that require large areas of fill.
• The rate of toner consumption will be normal and toner yield will be much closer to the estimate if
the documents contain mostly text.
Images become pale or scratchy
