PostScript Feature Dependencies/Caveats
• All %% commands (DSC comments) must be in the first 4096 bytes of the job.
• When you use duplicate commands, the last command takes precedence. Since the
setpagedevice commands are normally after the %% commands (DSC comments), the
setpagedevice normally takes precedence.
• The WorkCentre Pro 65/75/90 supports PostScript resolutions up to and including 1800
x 1800. Some PostScript jobs may not print if you use this resolution. If this occurs, print
the same job at a lower resolution.
• Do not duplex any job with media smaller than A6 (5.8 x 8.3 in. or 105 x 148 mm).
• Do not duplex any transparency or label jobs.
• To use the duplex front and back imaged covers option most effectively, remember
these items when you prepare the contents of the print file:
− The WorkCentre Pro 65/75/90 uses the contents of the first two and last two pages of
the file as the front cover, inside front cover, back cover, and inside back cover.
− The remaining pages print on the document body media type and color.
− If a print file contains an odd number of pages, the WorkCentre Pro 65/75/90 leaves
the last body page (that is, the page adjacent to the inside back cover) blank.
• When using the Blank Front or the Blank Front and Back Cover command, the Cover
Media Size command is optional. If the Cover Media Size command is not in the PDL,
the printer uses the media size of the document body.
• Use one of the following methods to specify media selection:
- Describe the media size, color, and type attributes and allow the device to select the
correct source tray. If you describe the media, leave source tray information out of
the request or set to Auto. Otherwise, the tray selection defeats the auto tray
selection capabilities of the device.
- Indicate the media feed tray the device should use. In doing so, you allow the device
to select media feed trays based on the paper type defined by SYSTEM DEFAULT,
unless specified otherwise. This method prevents inadvertent use of special paper
types. To override a paper type definition, include a paper type specification of
UNSPECIFIED in the job.
