Firmware upgrade reminders

Firmware upgrade reminders (MOJA - GAIA)

Upgrading firmware

IMPORTANT:
Always evaluate the firmware update on one device in the customer-specific ecosystem and verify functionality before proceeding to update a fleet of devices.

Any device running FW23 or older (xxxxx.230.yyy or smaller numbers) must first update to a FW24-based release such as xxxxx.240.246 before upgrading to FW25-based or newer releases (xxxxx.250.033 or larger numbers).

Any device running FW5.2 or older (xxxxx.052.yyy or smaller numbers) must first update to a FW7-based release, such as xxxxx.076.308 before upgrading to xxxxx.081.015 or newer.

MS/MX32x-62x devices and their equivalents running FW22.1 or older (xxxGM.221.999 or smaller numbers) must first update to a FW23-based release, such as xxxGM.230.329 before upgrading to xxxGM.240.043 or newer.

Contact Lexmark Technical Support to obtain intermediate releases if needed – note that if upgrading firmware using Lexmark Cloud Fleet Management or the “Update from Server” button on the device panel or web page, the server will automatically send any necessary intermediate firmware releases to the device in a stepped upgrade process.

Downgrading firmware

Firmware downgrade is no longer supported. If a firmware downgrade is required, please get in touch with Lexmark Technical Support and refer to the KB topicSO8017.

Downgrading firmware can result in exposure to known security vulnerabilities and will result in the loss of Apps, Security Features, and Settings.

Ensure the firmware you download is the correct one for the product you have.

Additional reminders

Check the device's current firmware level. Refer to “Checking the latest Lexmark printer firmware.”

Check the device's current firmware level.

If you are aware of any firmware installed on the device that is not standard, please contact customer support to receive additional firmware update instructions.

Review the release notes before deciding to update the firmware.

Format nomenclature change

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 Multifunction (S
= single function printer (SFP), X
= multi-function printer (MFP))

C
tells whether the UI is a touch screen or non-eSF or “lite feature set” (T
= touch screen, 4.3” or larger screen, N
= non-eSF and non-lite, L
= lite)

DD
tells the model family

AT
– (CS/CX 72x Series)

BL
– (CS/CX 33x Series)

BN
– (CS/CX 43x Series)

GV
– (CS/CX 53x, 63x Series)

MH
– (CS/CX 92x Series)

MM
– (CS/CX 73x Series)

PC
– (CS/CX 93x Series, CX94x Series)

PP
– (CS/CX 82x Series)

ZJ
– (CS/CX 42x, 52x, 62x Series)

BD
– (MS/MX 33x, 43x Series)

CT
– (MX432 Series)

GM
– (MS/MX 32x, 42x, 52x, 62x Series)

GW
– (MS/MX 72x, 82x, Series)

PM
– (MX93x Series)

SG
– (B2236 and MB2236 Series)

SN
– (MS/MX 53x, 63x Series)

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.
