2.   Print a list of fonts for the type of data you are printing. See “Printing a List of PCL Fonts” on page 27, “Printing a List of PostScript Fonts” on
page 28, or “Printing a List of IPDS Resident Fonts” on page 28. Jobs unexpectedly print one-sided or two-sided Your application or driver settings override the default set using the DUPLEX
item on the Paper Menu. Make sure that the application, driver, or both
specify the correct duplex setting. PostScript printing problem If your printer is not printing PostScript jobs correctly, the printed output will
be unformatted and will include unrecognizable characters (including %%
identifiers and other font information). Some print jobs such as screen dumps
and PCL jobs may print correctly.
1.   Make sure you have a PostScript printer driver installed and that it is       connected to the correct port.
2.   If you use either an Ethernet or token-ring connection, make sure the       PERSONALTY item in the NETBIOS Menu, Appletalk Menu, or Netware
      Menu is set to AUTO or PS. AUTO allows the printer to handle any data
      stream; PS dedicates the card to PostScript jobs. If PERSONALTY is set to
      PCL, you cannot print PostScript jobs using the card.
3.   Set the PRINT ERRS item to ON in the PS Menu (see “PS Menu” on page 90). If you get a PostScript error page, call technical support. IPDS printing problem 1.   Print a configuration page. See “Printing the Printer Configuration Page”  on page 24. If the controller recognizes the IPDS feature, the configuration
page will list the IPDS menu and Installed options will list “IPDS”. If IPDS
is not listed, remove and reseat the IBM AFP/IPDS Module. If reseating
the IBM AFP/IPDS Module does not correct the problem, replace the IBM
AFP/IPDS Module. 2.   If you use either an Ethernet or token-ring connection, make sure your printer is configured for TCP/IP. You cannot send IPDS jobs to the printer
using an Ethernet or token-ring card that is not configured for TCP/IP. See
Ethernet and Token Ring Configuration Guide for more information about
configuring Ethernet and token-ring cards. Poor quality shading patterns 1.   Make sure the QUALITY item in the Config Menu is set to REFINE. See       “Configuration (Config) Menu” on page 83. Also make sure your printer
      driver or printer application specifies Edge Refinement. Values set in print
      jobs (either by the print application or the printer driver) override values
      you set at the printer.
2.   Try increasing the print density if shading is too light. If shading is too dark, try decreasing print density. See “Adjusting Print Density” on
