     If you are receiving unwanted extra pages or the
     printer is not ejecting a page when you expect it to,
     one of the following conditions and or commands may be
     the cause.
     When the printer has something in its buffer, the form
     feed light will be on and a page will be ejected when
     any of the following conditions occur:
     1.   When the printer receives a FORM FEED control
          character from the computer system or from the
          form feed button on the control panel of the
          printer, the current page will be ejected.
     2.   The PERFORATION SKIP REGION is located below the
          bottom margin.  When the printer's cursor reaches
          this region at the bottom of the page, the printer
          ejects the current page and transfers the
          remaining data to the top margin of the next page.
     3.   When the printer receives the PAPER SOURCE CONTROL
          SEQUENCE (Ec&l0H) with a value of zero, the
          current page will be ejected; or if the printer
          receives a paper source command (Ec&l#H) the page
          will eject since the printer can only print from
          one source per page.
     4.   A RESET (EcE) will eject the current page.
     5.   A PAGE SIZE OR PAGE LENGTH command (Ec&l#A) or
          (Ec&l#P) will eject the page since the printer can
          only format one page size on each page.
     6.   An ORIENTATION CHANGE (Ec&l#0) will eject the page
          since the printer can only print in one
          orientation on each page.
     In addition, if you are using a stand-alone computer
     (one that is not connected to a network or sharing
     device), check the autoexec.bat and config.sys files
     for a line referencing "sp" or "spooler."  A line
     activating a ram spooler can cause a blank page to be
     ejected between print jobs.
     Networks and\or sharing devices are also suspect when
     getting unwanted extra pages.  Remove these and print
     directly to the printer when troubleshooting this
