imagePROGRAF PRO-310 Prints are off-center and have dark lines on the sides

laxinid675 — Wed, 21 Jan 2026 13:31:18 GMT

I have used the pro-300 for several years now and just purchased the pro-310 last week. I usually print on 13x19" and other custom sizes and didn't have any issues until just now when my print-out started to print off-center and dark lines on either side (photos attached). I'm not sure what the issue is and would love any advice that anyone can provide. Thank you!
