Other potentially-helpful information: I was clued in to the involvement of the printer when I noticed that DaVinci Resolve (video production software) was hanging on startup when my printer was powered on. On the support forum for Resolve, it was suggested that the software was scanning USB for storage devices. This printer includes a USB and SD port on the front for saving scans or printing photos. These are accessible by Windows as removable drives. To mitigate the problems with Resolve starting, I started powering down the printer after each use, which also corrected the system startup issue.

I cannot understand the physics behind the reflection and polarization-reflection on an atomic scale. What exactly happens at the boundary of two surfaces? I was studying Brewster's law and thus this doubt came.

You might also examine the BIOS/UEFI for any factors that might influence that interaction, although there wouldn't be many of them.

You may find downloads for this printer on the MFC-J895DW Downloads page, where you choose your operating system to get a list of the downloads, although the printer firmware is an independent download.

The oscillating electric field produced by an oscillating electric dipole is maximised at right angles to the oscillation direction. i.e. in the plane of incidence for s-polarised light. It is zero along the axis of oscillation.

Shining light perpendicular to a surface does not influence the random oriented E- and B-field. But shining light not-perpendicular, the surface influences the orientation of the lights field components. (BTW, the same happens with light in front of a polarizing foil or at the boundary of slits.)

For the hardware angel, you could try other USB ports. Testing the printer on another computer will give more information, but might not point to the problem.

The documentation (p. 32) on "Legacy USB Support" is a bit vague: I couldn't tell whether setting it to "Disabled" would only prevent booting a legacy OS from a USB device (which would be fine), of if it would prevent USB devices from functioning altogether outside the UEFI setup.

In the end, the amount of polarized light depends on the angle of light propagation to the surface. The surface influences the orientation of the E and B field at most for a certain Brewster angle.

As you may noticed the direction of z is default by the direction of propagation. But the x- any y-direction could have any orientation around z.

Circularlypolarized light

After months of thinking there was a faulty memory module or some other hardware problem with my build, I finally associated the symptoms with my printer of all things. If the printer is powered down (and not just in standby/sleep), the computer starts normally, and there is only a few seconds delay between the initial beep and the second one at start of the POST.

On an atomic scale, atoms emit light like a phased array of individual antennas. Then interference happens, and you get all the behavior of Snell’s Law, Fresnel Equations, etc.

If the reflected light ray is either side of the Brewster angle, then the oscillating dipoles would be viewed at an angle (less then 90 degrees) to the oscillation direction. Thus there would be some electric field produced in that direction, but not as much as for the case of s-polarised light, where the dipole oscillation direction is always perpendicular to the reflected ray.

Light as part of the electromagnetic radiation consists of photons. These quanta have an oscillating electric field component and an oscillating magnetic field component, both perpendicular to the direction of propagation. In vacuum the electric and the magnetic field components are exact perpendicular to each over. To make it imaginable for you, take a Cartesian coordinate system, orient z to the direction of propagation. The directions x and y are the directions of the E-field and the B-field.

s-polarised light causes these dipoles to oscillate perpendicular to the plane of incidence, in the same direction as the oscillating electric field of the incoming light.

Sep 18, 2024 — Crown glasses are optical glasses with low chromatic aberration (Abbe number above 55 or 50) which tend to have low refractive index.

Any idea of UEFI settings (or other changes) that might stop the problem outright without having to power down the printer all the time?

This problem is happening in the BIOS/UEFI with its interaction with the printer, so the first action should be to update all the involved software/firmware.

Now consider p-polarised light. The electric field is polarised in the plane of incidence and causes the dipoles to oscillate in the same plane. However, at a certain angle, the Brewster angle, the reflected light would need to be produced by electric dipoles oscillating along the line defined by the direction of the reflected ray. But no electric field is seen in this direction because it is the axis of oscillation for the dipoles. Thus no reflected p-polarised light is seen at the Brewster angle.
