Known issue with these devices. You have to open the device and clean the internal mirrors. Start with removing both side panels. Remove side parts (2 screws on each side, can be moved to the back and removed).Unscrew 4 screws (2 on each side) and remove the scanner/button unit (separating the upper part) Remove the screws holding the scanner unit, remove front buttons. Remove top cover so scanner unit (black) becomes visible. Remove black top cover on the scanner unit. Clean all mirrors. They are fragile. Front surface mirrors, so the mirror part is in front of the mirror, not (as a normal mirror) behind the glass. Due to continues heating/powering up, these mirrors become dirty. (You'll notice a 'white dust' on it). Clean them carefully and reassemble the printer. Most likely, it now will pass the scanner warming up procedure.

Yes. There is a huge difference between a 1-watt laser and a 1-watt light bulb. A 1-watt laser will burn a hole in your eye.
Is looking at a laser more dangerous than looking at a light-bulb of the same intensity?
Yes, looking at a laser can be more dangerous than looking at a light bulb of the same intensity. This is because lasers emit highly concentrated, powerful beams of light that can cause eye damage much more quickly than the diffused light from a light bulb.
How is laser light different from a light in a light bulb?
Laser light is different from light in a light bulb because it is focused, coherent, and monochromatic. This means that laser light is concentrated, all the waves are in step with each other, and the light consists of a single color or wavelength. Conversely, light from a light bulb is diffuse, incoherent, and contains multiple wavelengths/colors.
