It's caused by the so called solenoid (clutch).
The glue between two metals (one of them is L type) becomes too sticky and causes timing control incorrectly and causes paper jammed.
They cause most of the problems of Minolta Magicolor 2300DL/W/2350...... & Epson AcuLaser C900/C1900/C1000/C2000......., jammed and improper printout.
Just clean up all the glue and put a thin electric tape instead and all will be done.
There are six solenoid (clutch) to be taken care off.
Three of them can cause 6020 error - Secondary transfer roller
pressing/separation error.
This can cause print too low (paper's top head too much blank area).
-- SL5 Second Transfer Roller Pressure Solenoid
-- SL3 Timing Roller Pressure Solenoid
-- SL2 Transport Roller Solenoid
One of them causes paper folder (about 3cm blank area) and jammed tail.
-- SL6 Fuser Loop Flapper Solenoid
Toner Cartridge Rack rotates control.
-- SL4 Cleaner Pressure Flapper Solenoid
Another one is at the bottom of paper input tray, can cause paper input timing wrongly and jammed.
-- SL1 MP Tray Paper Feed Solenoid
Not an easy job to do even if you have the service manual.
Good luck!
