[mod.computers.laser-printers] Top Margin problem on Talaris Laser Printer

depaolo%marlin@NOSC.ARPA (Anthony D. dePaolo) (12/11/85)

When using our Talaris 800, there is a 0.4" margin that is imposed on the 
top of the page on all output, making it impossible to print on this part
of the paper.  When in QUIC command mode, regular text and line graphics
cannot use this space and if you want to print something at 1.0" down the
page, it really prints at 1.4" down.  However, when drawing arcs and when 
in vector mode, this offset does not occur, an arc or vector will print
at 1.0" down if the command line dictates this.

Anyone with a similar problem, or any solutions?  Thanks in advance.

The problem is in the way a switch is set located on the cannon adapeter
board in the Talaris controller box. SWS6 (Software Switch 6) can be set to
change the paper's refererence point (Registration). Bits 1-4 control movement
in the horizontal direction and bits 5-8 control movement in the vertical
direction. There is, however, a print engine limitation which will not permit
printing in about a 1/8 inch region on the left side of the page (in portrait 
mode). By setting the registration properly, all QUIC commands will in fact
be accurate. For further information read the Quality Micro Systems LG800
operators manual which gives instructions regarding the registration adjustment.
If you have problems in performing the adjustment, Group Three Electronics
will be happy to send a trained service engineer to perform the adjustment for
you at the standard fee. Call (408) 747-1600 for information regarding service.
