Mechanism Prevents Photoconductor Scratches on IBM InfoColor70 Printer

      Disclosed is a hardware means to prevent sideways motion of
paper from scratching photoconductor drum surfaces during servicing
of the IBM* 3170 Full Color Digital Printer and the IBM InfoColor70
Printer*.

      The photoconductor drum in the InfoColor70 Printer is easily
scratched.  To extend the useful life of the Photoconductor (OPC)
drum, it is necessary to prevent scratches from occurring.  During
servicing of the printer, paper may drag against the photoconductor
surface.  The paper edges and particles on the paper surface scratch
the photoconductor any time the loose paper web is moved vertically
or laterally against the drum.

      A mechanism automatically moves the paper web away from both
the X side and the Y side print stations and holds the paper in the
air with working clearance for servicing the printer without
scratching the OPC.  A paper web holding bar and roller is attached
to the X-tower,  as shown in the Figure, and arranged in such a way
that the bar does not  make contact with the paper when the towers
are in the closed operating  position.  When the towers are
separated, the bar lifts the paper away  from the Y tower while also
keeping it away from the photoconductor drums  in the X tower.  The
position of the bar is adjustable to increase service clearances to
either the X side or the Y side.  A roller is the  only contact with
the paper allowing...
