The only time I use a carrier is with photo-resist to keep from contaminating the rollers with resist. Even then, only a thin paper carrier is needed.
Also, I added a foot switch to mine to stop the drive so I can carefully get everything in place before running the material. With photo-resist, it is easier to hold the film away from the board as it feeds. I get less bubbles / pinholes that way. Or, in some cases, I apply the photo-resist using a printer's brayer, then laminate.

A PCB does not require a carrier.
I tape the artwork to the PCB with blue painters tape. The other side
of the PCB is bare.
A common reason for bad transfers is a laminator that is not hot enough.
If in doubt let it run longer prior to using it. Even the units with a
ready light can get warmer if allowed to warm up for a few extra
minutes.

the roller and feed out the back?
