There is a reason
Most Copier manufacturers state in the installation requirements that the device should not be located in direct sunlight. Some even say strong light.
The worst one I have seen was in an estate agents front window in full glare of the afternoon sun. Normally not an issue as long as the only real effect is to bleach the panels a horrible colour. Unfortunately some idiot thought drilling a few holes in the copier to mount a keyboard was a good idea. They managed to get some of the holes in the right l place but the uncovered test ones managed to let light bounce inside and onto the drum.
2cm of black nasty tape and telling off and they were mostly happy.
