Set the paper guides correctly.

Do not remove paper from the tray during printing.

Before loading, fold and straighten the stack of paper or fan out the edges.

Do not load different types of paper at the same time.

Remove the jammed document slowly and carefully, otherwise it may tear.

To prevent jamming of documents printed on thick paper, thin paper, or mixed paper, copy and scan such originals from the exposure glass.

Samsung SCX 3400 firmware via usbprns3. This article provides general recommendations on the profession of flashing Samsung printers through the usbprns3 flash driver.

First of all, we print the report: Menu#1934 - in the TechMenu select "configuration reports" and "consumables".

All we are interested in is what firmware version, isn't it letters F in the report and the CRUM number. We will sew through usbprns3, which can be downloaded from our file archive (section Additional software).

The firmware process is shown below in the screenshots. The program does everything automatically. You are only required to enter CRUM.

After pressing FIXIT waiting for the end of the printer firmware process

The printer is restarting. We take out the chip. This completes the whole process. The CRUM connector can not be touched by new firmware versions; they do not remember it.

Another firmware option, for older versions:

We print reports. . In this case, we print the report by pressing and holding the button STOP

When indicated - flashes 2 times green Configuration Report is printed. If the stop button is held for a long time, the Supplies Report is printed.

In the configuration report, we are interested in the firmware version - in this case it is 06 and what is written in quotation marks (please note that the firmware version without the letters P and F means the printer was not sewn and SCX3405 without letters, then the printer is 3405)

And consumables report

Here we need a crum number, we have all the information we have, we proceed to receive the firmware.

Sew via usbprns3, the link is above. The printer is connected. The driver is installed (not necessary, but got up automatically). Enable usbprns3. Let's go to main. We see the following - the program has determined the type of printer (3400), determined the serial number.

Further actions on the screenshots:

After checking the fix, click FixIt. At this point, the printer can "fall asleep", you can "wake it up" by pressing the "Power" button. The strip from the bottom goes to the end. At this time, do not touch anything.

Samsung firmware on the example of SCX 3400FW in pictures (Below is an article about firmware 3400 - the old version)

The firmware takes about 5 minutes. If the firmware is being delayed - you are here

Careful reading of the articles will save you a lot of problems in the future. Articles are constantly updated so that it makes sense to look back from time to time and refresh your memory or learn something new.

Let's get started.

1) We have a printer in front of us - we print reports. I printed through Menu # 1934 - in TechMenu configuration reports and consumables.

All we are interested in is what firmware version and if there is an F in the report. And a CRUM number.

I sew from usbprns3

The firmware process on the screenshots. The program does everything automatically. From you only fill CRUM.

After pressing FIXIT, we wait for the end of the printer firmware process

The printer is restarting. We take out the chip. This completes the whole process. The CRUM connector can not be touched by new firmware versions; they do not remember it.

And just in case, I left the old article.

1) We have a fresh Samsung SCX 3400 printer

The printer is already connected. Firewood installed (not necessary, but got up automatically). Enable usbprns3. Let's go to main. We see the following - the program has determined the type of printer (3400), determined the serial number.

Further actions on the screenshots

After checking the fix, click FixIt. I had to wake up the printer (by this point he had already fallen asleep by pressing the power button) The strip from the bottom goes to the end. WE DO NOTHING DURING THESE MOMENTS!!

Actually the printer started sewing. The process is short. We are waiting for the printer to restart.

Actually everything. But on this model it is highly desirable to disconnect the CRUM connector. So it is calmer in the future.

Disconnected

This is done in order - if in the future the client puts a cartridge with a chip, the printer will not change the internal crum to a new one. And the firmware will remain operational.

Finishing touch.

I remove the chip and print a report.

The printer is lit green. Letter F on the report.

All firmware linked to CRUM-number should be generated ONLY for original chips! With Chinese, etc. will not work!

For firmware, you need to know:

1. CRUM number is the serial number of your chip in the cartridge.
   You can find out your CRUM number by printing the Supplies report .
2. Firmware version is the printer software version.
   You can find out the Firmware version of the printer by printing Report configuration .

Printing reports

The SCX-3400 series printers have a button: "Stop \ Reset", it is with a cross.

How to get Report configuration:

From the “ready” state (the printer is on, it is green), press and hold the button Cancel, the indicator flashes, release the button, the printer will print Report configuration .

How to get the Supplies report:

From the “ready” state (the printer is on, it is green), press and hold the Cancel button, the indicator will blink, continue to hold when it becomes permanently lit, release the button and the printer will print Supplies report.

If the reports do not print because the toner is already blocked, then you can print from those menus. Do this: Press the following keys quickly: “+”, “+”, “STOP”, “-”, “-”, “STOP”, “STOP” The display should show “UC” Press the “+” button several times until “AA” appears on the display Press the “START” button A report will be printed containing the serial number and firmware version

Printer Firmware

The firmware created on CRUM is almost no different from the firmware with a serial number. The only condition is during firmware, the chip must be in the cartridge.

After creating and downloading the firmware:

1. Unzip the contents of the resulting archive to your desktop. You will see two files: firmware file and usbrns2.exe.
2. Connect the printer to the computer via USB. For firmware, it is not necessary to install a printer driver.
   Attention! During the firmware, you must not allow the power to turn off!
3. Download firmware.
   Be sure to flash with a chip!
   Drag and drop the firmware file onto the usbrns2.exe file. A DOS window will appear and dots will run - the printer is being flashed. Be sure to wait until the end of the process!
4. After the firmware is finished, the toner counter will be reset to zero, and will be reset every time you turn on the printer or open the cartridge cover. Now you can refill the cartridge multiple times. And it doesn't matter if you have a chip or not, empty or full.
   After the firmware, you can see the result of the firmware on the printer report.

Samsung SCX-3400 paper jam accordion

A fairly common problem with this model is that when the sheet leaves, its lower part is crumpled in the form of an accordion. Below, an explanatory note from the client and an accordion

I’ll make a reservation right away, the Samungians themselves admitted their shortcomings and change the device, or fix the malfunction under warranty! So, subject to the terms of the warranty, we safely take the device to the warranty service center. Jam culprit - "shashlik", or rather - rubber rollers. Whether their diameter is not the same, or the rubber itself, or whether they scroll is not clear.

JC91-01070A Exit shaft assembly ML–2160/ 2165/ SCX-3400/ 3405- it is enough to replace it and the malfunction will go away.

Solutions

Some tape is wound under rubber rollers, others put rubber bands from the HP 1100 output shaft (from parsing). Let me share my way...

In my case, I do not increase the pressure of the rollers on the sheet, as many do, on the contrary, I weaken ...

First of all, you should remove black beak, which is located on the bottom of the oven lid and presses the barbecue

Then, we get to the barbecue, remove it

Under the output shaft are four plastic rollers on springs. We take pliers and remove 2 links of each spring, thereby weakening the pressure of the rollers on the sheet. You don’t need to remove a lot either, otherwise there will be no adhesion to the sheet and jams will appear!

In order not to bite a lot at once, you can remove one link at a time, put it in place and check.

That's all. Several devices have been made in this way and work properly.
