– Not enough storage
– Specific PDF test cases sending data outside of page boundaries
– The system detects that the headset is unplugged while the printer is in sleep mode

Known issues:

– Some MFP devices may intermittently experience a “Service Scanner Failure [845.03] “Rear Cable Failure” error occurs when performing duplex scanning. A firmware fix for this issue is in progress. Please contact Technical Support if necessary.

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 if the device is currently running FW2 or FW3 based code, check the firmware version on the device. FW2 and FW3 based code will have the following version format: 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 xxxxx.080.001 or newer firmware cannot have their firmware downgraded below the manufacturing level
– For all other devices, firmware downgrades are strongly not recommended
– Downgrading the firmware from a newer Main Firmware EC to an older Main Firmware EC will result in the loss of applications, security features and settings.
– Contact Lexmark Technical Support and refer to KB article SO8017 for more information on the impact of the downgrade.
– Make sure you download the correct firmware for your product

Understanding firmware nomenclature:

Starting from FW4, the firmware version naming pattern is 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 multifunction printer (S = Single Function Printer (SFP), X = Multifunction Printer (MFP))
– C indicates whether the UI is touch, non-touch, or “Lite feature set” (T = touch, 4.3″ or larger, N = non-touch and non-lite, L = lite)
– DD told Model Family
– xx indicates the major firmware EC version, y indicates the minor firmware EC version (050 = FW5.0, 051 = FW5.1, etc.)
– zzz tells the version number of the firmware in EC
– FW2 or FW3 firmware versions are named in the format DD.xxy.zzz and use the same mapping as above. However, the DD model family used on FW2 and FW3 has changed on FW4 and later: ATL on FW2 and FW3 becomes AT on FW4 and later, CB on FW2 and FW3 becomes AT on FW4 and later, YK on FW2 and FW3 becomes PP on FW4 and later

About Printer and Scanner Firmware:

Before you consider installing this firmware, go to your device’s System Information page and make sure the currently installed version is not newer or incompatible with this version.

If you upgrade to this version, your imaging device can expect improvements in print and scan quality, new options in the settings menu, feature enhancements, various fixes, and other changes that improve stability.

Given the large number of devices and manufacturers, as well as the various methods for upgrading the imaging unit, we recommend that you read the installation steps and initiate the firmware update process only when you are familiar with the process.

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

So, if you plan to use this version, click the download button and install the package. Remember to check our website as often as possible so as not to miss any new releases.
