PRODUCT DIFFERENCES/USER CONSIDERATIONS
deletion will be noticed if no data is printed on the portion
of paper that extends past the blade.  
If you frequently use non-standard size paper, a custom
transfer blade kit is available for installation on your printer.
For more information on the custom transfer assist blade,
refer to the Xerox 4635 LPS Operator Guide.  
The activation of the blade is timed to place it on the lead
edge of the sheet of paper as it moves through the system.
The placement of the activation can vary with the actual
speed of paper.  Therefore, performance may demonstrate
some deletions on the lead 0.25 inches/6mm of the page.  In
particular, solid black lines on the lead edge of the page
should be avoided if this is a major concern to you.
A consideration resulting from the very solid black characters that
the 4635 LPS can print is that toner on the lead edge of the
paper may cause the sheet to stick to the fuser, due to the
consistency and solidness of the toner.  In order to eliminate
fuser jams caused by this condition, the system uses a digital
screen to lighten automatically any solid areas printed in the first
0.25 inches/6mm of the lead edge.  If the solid areas are small,
the amount of screen is barely noticeable, if at all.  However,
with very large solid black areas, the effect may not be
acceptable.  The system does provide an override using the Lead
Edge Screen window at the PC UI, or the EDGE command
entered at the command line.  This window or command allows
you to enable or disable the lead edge screen; however,
overriding the screen in this manner is likely to increase fuser
jams.
For particular applications, it is recommended that you run test
prints both with and without the screen to ascertain which mode
is most appropriate for you.  
For more information on the Lead Edge Screen window, refer to
the Xerox 4635 LPS Operator Guide or the Xerox 4635 LPS PC
User Interface Reference
.  For more information on entering the
EDGE command at the command line, refer to the Xerox 4635

Print Darkness
The 4635 LPS provides you with capabilities for tuning your
output print quality to meet the particular needs of your
application.  The Print Darkness window at the PC UI is a feature
which allows you to adjust darkness of printed characters and
images.  Print darkness is a scale from 1 to 9, which either
darkens or lightens the image, as well as broadening or thinning
the look of various characters.  The nominal setting is 5, which
provides the optimal mix of darkness and line thickness.
It is recommended that you test the Print Darkness feature to
determine the best setting for your site or application.  For more
information on the Print Darkness window, refer to the Xerox
4635 LPS Operator Guide
 or to the Xerox 4635 LPS PC User
Interface Reference
.  For more information on entering the
DARKNESS command at the command line, refer to the Xerox
4635 LPS Operator Guide
 or the Xerox 4635 LPS Operations
