The feature is included in the latest firmware for the following models: LJ4345mfp, CLJ4730mfp, LJ9040/9050mfp, CLJ9500mfp, M3027/3035 MFP, M4345 MFP, M5025/5035 MFP, CM4730 MFP, DS9200C, and DS9250C.

Users now have the ability to set the time zone for the MFP. When Automatic Daylight Saving Time Adjustment is enabled, the MFP will change the clock, based on the configured time zone. Time zone settings are current for the 2007 Daylight Saving Time start and end dates in the U.S. and Canada. Custom settings are also allowed. The device can be configured via the control panel, the EWS (Embedded Web Server), or WJA (Web Jetadmin).
PAGE 3
There are normally four tabs across the top. If only the Information tab is visible (as above), you must Log In, using the device’s EWS password.
PAGE 4
The Date & Time screen will appear, as shown below. The MFP’s date and time settings are displayed, and can be changed from this screen. The currently configured time zone is displayed, but cannot be changed from this screen. The firmware versions listed in the Release 1 column in the table will display GMT as the time zone for an unconfigured device. The Release 2 versions set the time zone for an un-configured device to “Not Configured”.

Click on the Advanced button at the bottom to access the Date & Time – Advanced screen: Page 5 of 9 white paper
PAGE 6
Select your time zone from the Time Zone drop-down menu. Check the Automatically adjust clock for daylight saving changes box Note: Your settings will not be effective until you click OK at the lower right. After clicking OK, you will return to the Date & Time screen. Click Advanced to return to the Date & Time - Advanced screen.
PAGE 7
The correct Daylight Saving Time start and end dates will be displayed for your selected time zone. Caution: If you did not click OK after selecting your time zone, the Start and End Dates will reflect the previously selected time zone. Using WJA: The screenshot below is the Configuration screen for WJA 8.X. All settings are entered from this screen.
PAGE 8
Notes and Cautions: For standard time zones, select the time zone, click on Time Zone, then click Configure. The Start Date and End Date settings will automatically be set for your selected time zone after you click Configure. The only time you would change settings in the Daylight Savings Time section would be to set custom dates and times. The Daylight Saving/Summer Time On checkbox is not used with these firmware revisions. It was only used with one prior MFP firmware revision.

Differences between Release 1 and Release 2: There are two primary changes from Release 1 to Release 2: Release 1 forces the user to enter the time zone via the control panel when a device is upgraded. This requires user intervention, which is problematic for remotely-managed devices. Release 2 does not display a Time Zone screen on the control panel. Release 1 displays the Time Zone screen, but the user could select Cancel.
