IPDS Firmware (EC6.0 and EC6.2) Known Issues


This document lists the known issues found when using Intelligent Printer Data Stream (IPDS) Firmware versions EC6.0 and EC6.2 on the 2012 released Lexmark printers.

EC6.0 (P632/1049)Printer gets stuck in Busy state when it prints any IPDS duplex job.
EC6.2 (P636/1049)Printers cannot flash firmware updates after they printed IPDS jobs.
Printer hangs when printing IPDS duplex jobs when a non-IPDS odd-paged duplex job is sent prior to it.


Updating the IPDS firmware to version EC6.3 will rectify the issues listed above. This firmware version is currently being developed with a target release within November 2016.

As a workaround, restart the printer to get it back on Ready state, and proceed uploading an EC5 IPDS firmware (P543/1049), where the issues are not found. Please contact Lexmark Technical Support to acquire the IPDS firmware EC5.

The Lexmark representative might ask for the printer's current firmware level. Please refer to xref_Check_xref for the steps. Once you obtain the file, you may proceed and update the firmware by following the steps from .
