Message says remove paper jam but there is no paper jam. What now?
Generally; if there is a sensor problem or stuck
sensor, this error will come up and stay on the display even after
turning off and on. If you are getting paper with a crease or fold, then
something is pulling or locking up in the paper path. Common causes could
be a pickup feed assembly, registration, underneath the cartridge, the
fuser or something in the output assembly. You could try a paper path
test and select it to print from different trays to see if the issue may
be just in one tray area or if it happens from all trays.
Saw your numerous posts at different times during 2009 and wanted to
let you know I posted a potential solution for you. Hope it works for
your situation... I've copied idea below for your review. Worked
perfectly for me 15 minutes ago.

removing the duplexer, grip any of the four rubber rollers and attempt
to rotate in either direction, if they don't move freely with little
effort, then continue with these instructions.
Take the first paper clip and contact the lower two brass rectangles,
this fools the device into believing the duplexer is installed, keep the
contacts bridged (don't remove your hand or the paper clip until Step
4.) THERE IS NO ELECTROCUTION RISK.
2. Press the "OK" button on the control panel to pretend the paper jam is cleared.
CAREFULLY OBSERVE THE pair of white gears on the left, if they seem to
clutch, stall, skip or freeze then you have paper shards which are
causing the jam.

left rubber roller and rotate in either direction , the gears should
rotate with your efforts and look for shards of paper in the gear teeth.
5. Use the paper clip, toothpick or any appropriate edged tool to clear the shards.

then you've cleared the insidious jam should be able to print until the
next error from this piece of chit printer.
