My 3 or 4-yearold MPS802 occasionally had problems with the ribbon losing
tension, in one direction (like a wet noodle). A quick squirt of Freon-TF
to the bottom of the little cluster of nylon gears which drive the ribbon
cures the problem nicely.  One of the gears is mounted on a small lever 
which is supposed to swing between two other gears as the printer-head
changes directions (The head can be moved by hand with firm, gentle force
while the power is off...to observe the lever action). A small amount of 
stiff grease had worked its way down  and retarded the "swinging" action.
