Lexmark XM1145 MFP Firmware LW74.SB4.P037/FDN.PIR.E714

Upgrade guidelines:

- This firmware release is intended for customers with current firmware versions LW73.xx.P034, LW72.xx.P030, LW71.xx.P025, LW70.xx.P022, or older (releases where the 2 digits immediately after LW are less than 70)
- If the current firmware on the device is LW70.xx.P200 or newer (releases where the 3 digits after P are greater than 200), do NOT update to this release. Contact the Technical Support Center for a newer version of firmware.

MS310d, MS310dn, MS312dn, MS317, MS410d, and MS410dn devices:

- If device firmware is EC5 or older, update the device firmware first to LW50.PRL.P593. After the device reboots, proceed to update firmware to EC6.0 or newer.
- This intermediate update is necessary due to increased code size of EC6.0 or newer and memory usage during code updates. If attempting to load EC6.0 or newer code over EC5 or older code other than LW50.PRL.P593, it can take up to or more than 90 minutes to update or it may fail completely due to an out of memory condition.

Non-eTask Models:

- If the device was originally manufactured with EC1 code or earlier, it is possible that the DBCS (Japanese, Simplified Chinese, Traditional Chinese, and Korean) characters may go missing from the front panel display after updating firmware.
- To fix this, simply send the updfonts.fls file included in the zip package to the device. This is a smaller version that fits in the space available with no loss of characters.

Downgrading to EC4.0 or EC4.05:

- Due to changes in EC4.0 and EC5, do NOT downgrade firmware from EC5 or newer directly to EC4.0 or EC4.05 based code. EC4.0 and EC4.05 code levels have names like LW40.xx.P4xx. This will cause a non-clearable 900 Service error. Contact the TSC for instructions on how to clear this error.
- This warning includes installing a DLE with EC4.0 or EC4.05 code into a device that currently has EC5 or newer code.
- Code levels earlier than EC4.0 can be sent to EC5 level devices without causing a service error.
- To downgrade EC5 or newer code to an EC4.0 or EC4.05 level, you must first load an EC4.1 based code. EC4.1 code levels have names like LW41.XX.P4xx. Once the device is at an EC4.1 level, EC4.0 code can be sent.
- According to the firmware FAQ posted on the support site, we do not officially support downgrading firmware. This is the reason it is not supported, even though great efforts are made to prevent these kinds of events from happening, sometimes it is unavoidable. We apologize for the inconvenience.

About Printer and Scanner Firmware:

Before you even consider installing this firmware, go to the system information page of the device and make sure that the version currently installed on it isn't newer or matching this one.

If you upgrade to this build, imaging devices can get printing and scanning quality improvements, new options added to the setup menu, feature enhancements, various fixes, as well as several other changes that can boost stability.

Considering the large number of devices and manufacturers, as well as the wide variety of methods for upgrading imaging units, we recommend that you read the installation steps and initiate a firmware update process only when you have familiarized yourself with the procedure.

In addition to that, it would be best if you perform this task in a steady power environment such as the one ensured by a UPS unit. Also, make sure you don't power off the imaging device or use its buttons during the installation, in order to avoid any malfunctions.

Therefore, if you intend to apply this version, click the download button, and install the package. Remember to check with our website as often as possible so that you don't miss a single new release.

  It is highly recommended to always use the most recent driver version available.

Try to set a system restore point before installing a device driver. This will help if you installed an incorrect or mismatched driver. Problems can arise when your hardware device is too old or not supported any longer.
