PRODUCT DIFFERENCES/USER CONSIDERATIONS
Virtual page size
The default virtual page size is identical to the physical page size.
If a virtual page size is user-defined, the virtual page is centered
relative to the physical page.  A user-defined virtual page may not
be larger than the paper size value; larger dimensions are
truncated.  
Error messages
If any part of a print line originates off the system page, the
following message is displayed: 
OS6905 DATA ORIGIN OFF PAGE -- CHECK OUTPUT
This message appears only once during a print job.  It indicates a
print line origin problem within the form description or an
excessive SHIFT value.  Refer to the Xerox LPS Forms Creation
Guide
 and the Xerox 4635 LPS Message Guide for more
information. 
Deletions
The 4635 printer utilizes the newest xerographic advancements,
providing good solid black print quality and spot control.
However, in certain circumstances, there is a possibility that
toner from the photoreceptor may not completely transfer to a
sheet of paper before it is fused and sent to the output bin.  This
occurrence is known as a deletion.  Generally, deletions will
result in a small area of the printed page appearing lighter than
the rest of the page.  For example, a few letters of a word may
appear lighter than the rest of the word.  
To help reduce the occurrence of deletion, the 4635 printer has
been fitted with a four-segment transfer blade which presses the
paper onto the photoreceptor during toner transfer.  This blade
is automatically activated based on the paper size setting in the
job descriptor and does not involve any operator interaction or
loss of productivity. 
There are two different transfer blades: one for 60Hz systems and
one for 50Hz systems.  Each blade can adjust to four paper size
lengths as follows: 
60 Hz blade: 11, 11.69, 13, and 14 inches (279, 297, 330, 356
mm)
50 Hz blade: 10, 11, 11.69, and 13 inches (254, 279, 297, 330
mm) 
Thus, if you switch from 8.5 by 11 inches/216 by 279 mm to U.S.
legal (8.5 by 14 inches/216 by 356 mm), the 11 inches/279 mm
segment is utilized first, then the additional blade extension to
14 inches/356 mm is activated automatically when the legal size
paper is encountered.
Two points to note:
For page lengths in between the preset blade lengths, there
may be some deletion on paper that extends past the blade.
The rate of occurrence of deletions varies widely, depending
on paper stock, and should be tested.  Also, note that no
