I did Samsung's firmware update CLP365W_Upgrade_Patch.exe and now the printer is flashing a green Eco light, a blue WPS light and a green Status light all at the same time.

hi try to make to do again firmware update, something went wrong on the previous update. the orange light is on becaouse the printer firmware is wrong, is in the upgrade mode.

Dear
The problem is at SMPS, you need technicians help.
Thanks.

I think I would get back to the Samsung Help website and ask

To solve problem you need to download PATCHED by scx4300.exe 1.13 firmware (which you can Google and download it online)where additional reset procedure was implemented in.
To patch firmware you need to unpack archive in any folder then open commad line interface go to this folder then type "fix4300.exe SCX4300_V1.13_Fact_romdl.hd". If no error occurs you will find file "FIX_SCX4300_V1.13_Fact_romdl.hd". It's a patched firmware. The next step is to download this file to printer. Enter TECH mode, activate download by "Menu > Data Setup > Flash Upgrade > Local [OK]" then type in command line "usbprns2.exe FIX_SCX4300_V1.13_Fact_romdl.hd" to start download. During download printer displays: Data receiving > Flash erasing > Flash Programming > Checksumming > Download Ok then printer will restart. It's all.
To reset all counters and unblock printer enter Tech mode go Data Setup > Clear counters. In this menu you will find "Clear All CNT" instead of "Total Page CNT". Choose "Clear All CNT" then press [OK]. Printer will display "warming up" and LED will yellow for seconds then change to green. After reset all counters in report will be zero and toner 100%. You may repeat this procedure as soon as you need.

There are a small number of #23/#24 cartridges that are not properly recognized by the printer. Lexmark has a firmware upgrade to correct this issue. The upgrade for the X3430 is available from Lexmark at:

• PC: http://www.downloaddelivery.com/downloads/misc/Firmware_D062209_3500-4500Series.exe
• Mac: http://www.downloaddelivery.com/downloads/misc/Mac_Chan_D062209_00.zip

To install the firmware upgrade,

1. Make sure the printer is ON and connected with a USB cable.
2. Download and run the appropriate firmware upgrade for your computer.
3. Be sure not to disconnect or power off the printer until the upgrade is complete

When the update finishes the printer will restart and will accept the cartridges. Please contact Lexmark support if this does not fix the problem.
This works for the X3550 and X4550 models. A similar patch is available for the X3430 and Z1420 models. See http://bit.ly/LoXxv

There are two different print engines used in the CLP-300. One for 2006, and a different one starting in 2007. I have the older 2006 printer, and the current firmware is only for the new 2007+ print engine.

I talked to Samsung support here in Korea and fixed the problem. They sent me to their special tech support website at www.1479.co.kr (only in Korean) and I was able to download an older version of the firmware which restored my printing ability.

The latest version of firmware that worked with my printer was found in this post: http://www.bassmania.co.kr

Download the two files at the top, then extract the archive. Drag-n-drop the correct firmware file onto "usblist2.exe" and the printer will be flashed with the firmware (must be connected via USB if you're using the CLP-300N model).

The upgrade for the X3470 is available from Lexmark at: http://www.downloaddelivery.com/downloads/misc/Firmware_F061909_3430Series.exe

Hello,

There is an update for your printer. This is a firmware update. A firmware update, rewrites code located on the printer's main system board. The latest update is dated 10/17/08.

Flashing firmware does not have a go back element or undo, so it is really important that we verify your model and what seiries of printer you have. I suspect you have a CLP-300 Series printer and that the 310 of the 300 just describes some features added or left off and even who you purchased it from, in many cases.

Please look at these two photos and then post the data off the name plate for your model number in particular.



You will notice there are two lines to include in your reply.
1.) The Model: (first line)
2.) M/C entry (second to last entry in this photo of the label.

Once you verify this and I post the firmware update link for you, you will need to follow the instructions I include below.

Regards,
Worldvet
