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 transitioning 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 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 upgrade procedure:
– Devices running ATL.03x.yyy or ATL.02x.yyy firmware (CS72x/CX72x and equivalent) must be updated to an intermediate version before updating to FW7
– The required intermediate version is CSTAT.041.090 or CXTAT.041.090, from there the firmware can be updated directly to FW7

Learn about firmware nomenclature:
Starting with FW4, firmware versions are named in the pattern ABCDD.xxy.zzz, where:
– A tells the printer whether it is monochrome or color (M = monochrome, C = color)
– B tells whether the printer is single function or multifunction (S = single function printer (SFP), X = multifunction printer (MFP))
– C specifies 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 tells the model family
– xx tells the major firmware EC version, and y tells 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 with the pattern DD.xxy.zzz, using the same mapping as above.However, the DD model series used on FW2 and FW3 has changed on FW4 and newer: ATL on FW2 and FW3 becomes AT on FW4 and newer, CB on FW2 and FW3 on FW4 and newer Becomes AT, YK on FW2 and FW3 becomes PP FW4 and newer

About printer and scanner firmware:
Before you consider 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 matches this version.
If you upgrade to this release, imaging devices get print and scan quality improvements, new options added to the settings menu, feature enhancements, various fixes, and several other stability-improving changes.
Considering the large number of devices and manufacturers, and the variety of ways to upgrade the imaging unit, we recommend that you read the installation steps and initiate the firmware update process once you are familiar with the process.
In addition to this, it is best to perform this task in a stable power environment, such as that ensured by a UPS unit. Also, make sure not to turn off the imaging device or use its buttons during installation to avoid any malfunctions.
So if you plan to apply this version, click the download button and install the package. Remember to check out our website as often as possible so you don’t miss any new releases.
It is strongly recommended to always use the latest driver version available.
Try setting a system restore point before installing device drivers. This will help if you have incorrect or mismatched drivers installed. Problems can arise when your hardware device is too old or no longer supported.
