You have a bad printhead unit(laser unit) . The polygon mirror is not rotating within a specific amount of time. I recommend you to replace your fax unless your willing to spend between 200 to 500 dollars.

There are two ways to fix your problem. First open your cover, then press the small white rounded reset button in the lower frame. The second method - unplug your fax, then hold down the stop and start key while pluging in the fax. When you see memory clear on the screen let go of the stop and start key. I believe the screen will say 1 for yes 2 for no for memory clear, press 1. The second method will ERASE every thing in memory that includes program #'s and transaction report setting.
