Models: 4410, 4440

Summary:
 Main control panel displays "P.O.", "L.P.P." and there is paper in the printer.

Resolution:
 


Main control panel displays " P.O."," L.P.P." and there is paper in the printer, 
and you cannot clear the error by pushing the Test Clear pushbutton, the possible 
problem may be occurring at the paper low switch, located on the bottom left 
tractor assembly.

To verify this, tape down the metal loop of the paper low switch and re-load paper 
into the tractor. If the error goes away the problem was due to a misadjusted switch. 
If problem continues, the possible fault may be intermittent crimp connections on the
contacts of switch, a defective switch,  or a defective SMIM PWB.
