Hi ll38ymrn
So that I may better assist you, I will need some more information about your situation. Do you mind answering a few questions?
(1) How are you connecting the mf628cw to your computer, with a USB cable or via your network?
(2) Does the light stop flashing after resetting your MF628Cw using the steps below? If not, what exactly is displayed on your printer's LCD screen?
1. Turn the printer off with the Power button.
2. Disconnect the data cable from the printer (not applicable to WiFi).
3. Unplug the printer's power cord for at least ten minutes, and then plug it back in.
Note: If the power cord is plugged into a surge protector, it may be necessary (for testing purposes) to plug the cord directly into the wall outlet if possible.
4. Turn the printer back on.
