Slow Fax Performance after Upgrading Hardware

Troubleshooting


Problem

This document provides information about slow fax performance after upgrading to new hardware.

Resolving The Problem

After upgrading the hardware and operating system, faxes take a long time to send (about 3 - 10 minutes per fax).

To resolve the issue, do the following:

1.Apply the latest Facsimile Support PTFs, hardware PTFs for the modem being used, and the latest Print Group PTF, which includes the latest Host Print Transform PTFs.
2.Delete and recreate the fax description(s).
3.Before starting Facsimile Support, determine/change the line speed for the fax line description(s):

WRKLIND LIND(FaxLineName)

From the Work with Line Descriptions screen, select option 2 to Change and verify that the Line Speed is 115200. If it is not 115200, change it to 115200 and press <ENTER>. Perform this step for all fax lines.

Note: The line speed does not show up when displaying the line description.
4.Restart Facsimile Support using the STRFAXSPT command.
