Dirty exit rollers could be an issue, especially if you have foam exit rollers and the foam is coming apart and depositing tiny pieces of foam on a not quite dry print.
I've been running RC paper dryers at home for around 25 years now, the prints from forced drying as opposed to hang drying, with or without the help of a squeegee, are virtually identical, although I would give the edge to any prints that have been through my RC paper dryer.
According to Ilford, forced air drying in their machines will give you the best results. Temperatures up to about 80ºC I seem to remember are alright, that said, with a bit of fiddling of the paper speed through my dryer, and a surface temperature from a direct readout off the paper surface of around 70ºC, I get excellent and print to print evenness and quality. As well as a continuous input/output.
Kodak paper, when I used it, was pretty much the same, as was Agfa RC paper.
