Improvements have been made for multiple sources of 900 errors, some of which include:

– Scan operation causes crash
– kernel error
– Specific type/content of print job

Known issues:

– If you need firmware for a specific device not shown at https://support.lexmark.com/en_us/drivers-downloads.html, please contact TSC
– CS92x and CX92x and their equivalent devices (CSTMH and CXTMH firmware versions) show the cartridge reporting 4% instead of empty, resulting in a 129.00, 129.10, 129.20, or 129.30 error code. To prevent light-color print quality issues, users can enable custom supplies notifications on the device via the web page or panel and assign each ink cartridge (black, yellow, magenta, and cyan). This custom notification prevents the 129.00, 129.10, 129.20, and 129.30 error codes from recurring and forces a new power supply to be plugged in. This is a temporary solution until a firmware fix is ​​available.

Firmware upgrade warning:

– If the current code level on the device is based on FW2 or FW3, it may take up to 20 minutes to update the device to FW7 code
– This is a one-time issue when converting a device from FW2 or FW3 to FW7
– To find out whether a device is currently running FW2 or FW3-based code, check the firmware version on the device. FW2 and FW3 based codes will have the following version formats: ATL.03x.yyy or ATL.02x.yyy, CB.03x.yyy or CB.02x.yyy, PP.03x.yyy or PP.02x.yyy, YK. 03x.yyy or YK.02x.yyy

Firmware downgrade warning:

– Devices manufactured with firmware xxxxx.080.001 or newer cannot downgrade the firmware below manufacturing level
– For all other devices, it is strongly recommended not to perform firmware downgrade
– Downgrading firmware from a newer primary firmware EC to an older primary firmware EC will result in the loss of applications, security features and settings.
– Please contact Lexmark Technical Support and refer to Knowledge Base article SO8017 for more information on the impact of downgrades.
– Make sure the firmware you download is suitable for the product you have

Understand firmware nomenclature:

Starting with FW4, firmware versions are named with the pattern ABCDD.xxy.zzz, where:
– A indicates whether the printer is monochrome or color (M = monochrome, C = color)
– B indicates whether the printer is a single-function printer or a multi-function printer (S = single-function printer (SFP), X = multi-function printer (MFP))
– C indicates whether the UI is touchscreen, non-touchscreen, or “Lite feature set” (T = Touchscreen, 4.3-inch or larger screen, N = Non-touchscreen and non-Lite, L = Lite)
– DD tells the model family
– xx represents the major firmware EC version and y represents the minor firmware EC version (050 = FW5.0, 051 = FW5.1, etc.)
-zzz tells the version number in the firmware EC
– FW2 or FW3 firmware versions are named in the DD.xxy.zzz pattern using the same mapping as above.However, the DD model series used on FW2 and FW3 changes on FW4 and above: ATL on FW2 and FW3 becomes AT on FW4 and above, CB on FW2 and FW3 becomes AT on FW4 and above Version changes to AT, YK on FW2 and FW3 changes to PP on FW4 and later versions FW4 and later versions
– Make sure the firmware you download is suitable for the product you have

About printer and scanner firmware:

Before considering installing this firmware, go to your device’s System Information page and make sure that the currently installed version is not a newer version or does not match this version.

If you upgrade to this version, imaging devices receive print and scan quality improvements, new options added to the setup menu, feature enhancements, various fixes, and several other changes that improve stability.

Considering the large number of devices and manufacturers, as well as the variety of ways to upgrade your imaging unit, we recommend that you read the installation steps and only initiate the firmware update process once you are familiar with the process.

Otherwise, it is best to perform this task in a stable power environment, such as that guaranteed by a UPS unit. Also, make sure not to power off the imaging device or use its buttons during installation to avoid any malfunctions.

So, if you plan to apply this version, click on the download button and install the package. Remember to visit our site as often as possible so you never miss a new release.
