It isn't normal at all.
And since we know nothing of the environment or stock it is hard to guess.
But since it feeds partially, and just stops with no damage you can safely assume a feed issue, because the sensors internally know exactly where the paper should be at all times, and when the sensor doesn't trip when it should (the paper isn't there) it stops the jam and declares a jam to stop the paper from being jammed when it is being misfed. So if the paper isn't crooked or anything, we know the roller isn't picking up the paper properly.
And that could have a few causes, improperly programmed paper (Coated stock that isn't set that way)
Static cling (Paper not fanned and flipped etc)
Humidity (paper sticks when moist)
Cheap paper stock not designed for printers
So...
Check that the humidity is in acceptable range in the room the printer is in, make sure you load entire reams of paper, not a few sheets at a time (Static build-up), Don't store the paper near an air conditioner.Make sure it is loaded in the machine properly (Not just size, but type and weight matters). Try rotating it in the tray 90 degrees and see if it works better, it could be you are buying long grain vs short grain paper.
This stuff happens to every printer
