When I print on Photo glossy (I’ve tried both on 300 GSM and 230 GSM) I get these indents? I’ve had the printer for just a month, and they’ve been doing it since. I do rear feed, and I’ve tried selecting the “thick envelope” option in settings on the PC. When I print on holographic it’s very fine dots in a perfect line. Any ideas what’s going on?
