Is there any trick you can perform to convince the printer to print envelopes? As far as I can tell, the printer detects envelopes as double feed of normal paper, which is understandable since envelopes is at various points up to 3 layers thick (or 4 if the flap overlaps the edges).
I have consulted with the firm who sold it, and they don't recommend printing envelopes at all since it can harm the drums, fuser etc. with the added thickness at specific points across the printing direction. They considered having extra hardware to swap in when printing envelopes, but that's not a viable option economically.
However, I have read somewhere about some kind of switch (DIP switch or software, I do not know) that disables the double feed detection, and I was wondering if anyone has any experience with this particular machine and printing envelopes, or any similar Konica-Minolta hardware.
Basically, is it possible to flip a switch, print the envelopes and then flip it back?
For reference, we don't print much envelopes, so we're talking maybe a maximum of 5000 envelopes per year, spread out over 10-15 occasions. For simplicity, say once a month maybe.
If we find that the volume increases (currently it is decreasing though) we would consider a different printer, so this is just a stop-gap measure if anything.
Any help and/or advice appreciated!
