CC-5 Troubleshooting If this happens: Jobs sent to the parallel port do not print (cont'd.) Try this: • If the PostScript Printer Driver that you are using lets you select bi-directional communication, make sure that it is disabled. This is generally set from the Properties dialog box for the printer. • If you are printing from a DOS window with Windows 95, display the Properties dialog box for the printer, click the Details tab, and then click Port Settings. In the Configure LPT port box that displays, turn the "Spool MS-DOS print jobs" option off. Problems with print quality If this happens: Print settings for your job output do not match the settings you gave You get poor printing results Separations do not combine properly The registration or colors of an image are not what you expected Try this: • Make sure that you did not override the setting for the job in another place. For information about options and overrides, see Appendix D, "Setting Job Overrides." • Does your application require the DocuColor's printer description files? If you are printing from an application such as Adobe Separator or PageMaker, MacroMedia FreeHand, or QuarkXPress, you should make sure that the DocuColor printer description file is installed correctly. For information about installing these files, see Getting Started. • Calibrate your copier using AutoCal. • Make sure that the file was initially created as separations. • If you are printing separations or a DCS format file, check the Combine Separations setting for the job in the Printer Specific Options (Macintosh)/Options (Windows) dialog box. With Combine Separations On, all four colors will be printed on a single page; with Combine Separations Off, four black-and white pages will print to simulate four singlecolor plates. • Print a test page or make a test copy with the copier. The problem may be with the copier. If your test page or copy show that the copier is working properly, correct the problem within your application software. If the test page or copy are wrong, your copier may need to be calibrated or adjusted in some other way.

Troubleshooting
Problems with print quality
Jobs sent to the parallel port
do not print (cont’d.)
•
If the PostScript Printer Driver that you are using lets you select bi-directional
communication, make sure that it is disabled.
This is generally set from the Properties dialog box for the printer.
•
If you are printing from a DOS window with Windows 95, display the Properties dialog
box for the printer, click the Details tab, and then click Port Settings. In the Configure
LPT port box that displays, turn the “Spool MS-DOS print jobs” option off.
If this happens:
Try this:
Print settings for your job
output do not match the
settings you gave
•
Make sure that you did not override the setting for the job in another place.
For information about options and overrides, see Appendix D, “Setting Job Overrides.”
You get poor printing results
•
Does your application require the DocuColor’s printer description files?
If you are printing from an application such as Adobe Separator or PageMaker,
MacroMedia FreeHand, or QuarkXPress, you should make sure that the DocuColor
printer description file is installed correctly. For information about installing these files,
see
Getting Started
.
•
Calibrate your copier using AutoCal.
Separations do not combine
properly
•
Make sure that the file was initially created as separations.
•
If you are printing separations or a DCS format file, check the Combine Separations
setting for the job in the Printer Specific Options (Macintosh)/Options (Windows)
dialog box.
With Combine Separations On, all four colors will be printed on a single page; with
Combine Separations Off, four black-and white pages will print to simulate four single-
color plates.
The registration or colors of an
image are not what you
expected
•
Print a test page or make a test copy with the copier.
The problem may be with the copier. If your test page or copy show that the copier is
working properly, correct the problem within your application software. If the test page
or copy are wrong, your copier may need to be calibrated or adjusted in some other way.
