Kyocera color machines do not have a web or any other cleaning method for the fuser. So after you've been running a bunch of edge-to-edge high fill photo images, the fuser can collect some residual toner that clears on the next few pages. Also a paper jam will leave toner on the heat belt. And if you've been running heavy paper on plain paper media settings you'll leave toner in the fuser.

For starters, make sure that the proper media settings are being used. Also make sure that the fixing temperature settings are at their defaults, and haven't been tweaked up or down. Do you want a long term cure? Design a cleaning web for the fuser. And while you're at it, there a few other machines that can use a web, too. =^..^=
