Firmware upgrade warning:
- It may take up to 20 minutes to update devices to FW7 code if the code level currently on the device is FW2 or FW3 based
- This is a one-time issue transitioning the device from FW2 or FW3 to FW7
- To know 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 firmware downgraded below the manufactured level
- For all other devices, it is strongly recommended that a firmware downgrade is NOT performed
- Downgrading firmware from newer major firmware ECs to older major firmware ECs will result in the loss of Apps, Security Features, and Settings.
- Contact Lexmark Technical Support and see KB Article SO8017 for more information on the impacts of downgrading.
- Ensure the firmware you download is the correct one for the product you have

Understanding firmware nomenclature:

Beginning with FW4, firmware versions are named in the pattern ABCDD.xxy.zzz where:
- A tells whether the printer is Mono or Color (M = mono, C = color)
- B tells whether the printer is Single or Multi function (S = single function printer (SFP), X = multi function printer (MFP))
- C tells whether the UI is a touch screen, non-touch or “lite feature set” (T = touch screen, 4.3” or larger screen, N = non-touch screen and non-lite, L = lite )
- DD tells the model family
- xx tells the major firmware EC version, while y tells the minor firmware EC version (050 = FW5.0, 051 = FW5.1, etc)
- zzz tells the release number within that firmware EC
- FW2 or FW3 firmware versions are named in the pattern DD.xxy.zzz using the same mapping as above. However, the DD model families used on FW2 and FW3 were changed on FW4 and newer: ATL on FW2 and FW3 becomes AT on FW4 and newer, CB on FW2 and FW3 becomes AT on FW4 and newer, YK on FW2 and FW3 becomes PP on FW4 and newer
- Ensure the firmware you download is the correct one for the product you have 

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.
