I’ve had my latex for a while now and never solved this issue which is common on a lot of materials. The medium doesn’t stay flat and raises in the middle causing the print to smudge. It’s only raises up across a 10cm zone. My work around is to run the take up roller as this helps flatten the sheet. I’ve increased vacuum but this doesnt always work. The material is raised even before ink or heat stage. I’ve released rollers on off to see if it’s a loading issue. The worst culprit is satin poster paper 200gsm. Any advice much appreciated.
Hi @paul7092, to rule out that the problem is related to the heat generated by the curing system, can you try to move the media through the front panel before launching the job just to check if the bubble is generating in the middle without heat.
If still happens it may be an issue from pinch wheels or any other part in the substrate path. In that case I suggest you contact HP support.
