improves performance. The illustration below shows collated and
uncollated stacking for two copies of a three-page file.
The face-down output bin has an offset stacking feature that when
enabled, offsets the multiple copies of a print job. With a hard disk
installed, collation performance is greatly improved because the file is
stored in QMS-compressed format for repeated printing. When disk
space is consumed during a print job, the printer begins chunk collat-
ing. Chunk collation breaks a job into sections and performs collation
on each of those sections. The next diagram shows the printing
order of three copies of a large document when chunk collation is
used. Several factors control the point when chunk collation occurs.
The maximum collation sequence is 100 sheets. Disk space of 10 MB
is probably sufficient for most printing applications. The maximum
