Software Problems

Most printer features are controlled by your software application. For more information, see your software documentation or contact your software vendor.

Here are solutions to common problems related to software:

Blank pages appear between printed pages.

Reason: Number of lines per page in software is not equal to number of lines per page of printer.

Solution: Many software packages assume 66 lines per page; your printer default is 60. Adjust software accordingly or set LINES/Pg in Menu 1 to equal lines per page in software.

Cannot get justified right margin with a proportionally spaced font. Reason: Right justification with proportional fonts is a software feature. Solution: Check your software manual to see if this feature is supported.

Control codes not operating correctly

Reason: Incorrectly entered control codes.

Solution: Check for confusion of the lower case letter l with the number 1, the upper case letter O with the number 0; make sure you are using upper/lower case correctly; make sure font is specified correctly and is available.
