Overview
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.
| Firmware | Issue |
| 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. |
Solution
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.
NOTE: 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 .
