SUBJECT: DUPLEX PRINTING IN LETTERHEAD MODE
SYMPTOM:
When printing odd pages in duplex mode with direction-sensitive paper (ex. letterhead, pre-punched, and/or
pre-printed paper), the last page is printed on the rear side instead of the front.
CAUSE:
With duplex mode, the machine prints the even-numbered page first onto the paper's rear side, inverts the
paper, and then prints the odd numbered page onto the front side. However when the total number of pages
is an odd number, e.g. 5 pages, the final sheet of paper is not inverted through the duplex unit, which means
that it is printed out onto the paper's rear side.
SOLUTION:
The Letterhead function is available with controller firmware (Version 2.11) only when the setting has been
changed to Enabled in SP mode (default: Disabled).
When selecting direction-sensitive paper (letterhead, pre-punched, pre-printed), along with the first sheet
designated as duplex, the machine also passes all sheets following this through the duplex unit.
NOTE: This does not apply to paper fed from trays for which the duplex function has been disabled.
How to activate "Letterhead" mode
1. Access SP mode.
2. Set Bit Switch 2-4 to 1.
Specification & Remarks
The following explains how the machine works with an example in each print mode.
(Illustrations show the order in which sheets are output to the internal exit tray.)
Example: 5-page duplex print job.
Printing page order: 2 -- 1 -- 4 -- 3 -- 5.
1st sheet: Pg 2 onto rear side ---> [inversion] --> Pg 1 onto front
2nd sheet: Pg 4 onto rear side --> [inversion] --> Pg 3 onto front
3rd sheet: (depends on paper type and feed station, as described below)
