Understanding how an image (copy) is made might help.
The drum goes thru a Basic process like this; charge,exposure,transfer,clean.
the paper only comes into play during the transfer stage. Since the drum has a static charge the paper gets attracted to the drum and needs to move at the same speed as the drum. After a small distance the paper has to be repelled from the drum with the print (sometimes called Detack), this can be accomplished by a Detack wire or a reverse of polarity applied to the paper.
If this doesnot happen paper stays on drum (jam).
So you need to see if the jam you remove has any ink on it, this would indicate a transfer issue maybe a detack problem.
If it is clean (never reaches the drum) then a paper feed problem is indicated.
Now you need to understand paper!
Some paper is long grain other is short grain. This is what gives the stack of paper a curl as you hold it by the edges (most paper has an arrow on the wrap telling which way to run paper (it means curl up / curl down basically). The problem with grain is usually when some cuts down 11 x 17 paper to save money to give you 8 1/2 x 11.
How do you tell grain fold paper in half long edge to long edge run your fingers down the edge if it is smooth you have long grain. Most copiers feed the long edge therefore long grain is what you need . If when you fold in half the edge is rough, then fold another top to bottom if seem is smooth you have short grain, This works better on top edge feeding copiers / printers, these are unusual since most they are slowest (mostly diazo printer).
Since you seem to have problems early make sure you remove paper every night and store flat, note the curl direction beacuse if when you put it in in the morning it might change curl (teacup).
Some times old machine use rubber rollers to start initial fee, these you could try to clean with some finger nail polish remover. This will eventually dry out the rubber but if it helps then maybe you only need to replace the rollers.
That was a quick lesson hope it helps.
