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.

Office equipment often breaks down, and sometimes there is no time and money to contact specialists. In the event that for some reason it is not possible to seek help from professionals, you can flash the printer at home. There are quite a lot of companies producing modern office equipment. The undisputed leaders are the Korean company Samsung, the American companies HP (Hewlett-Packard) and Xerox.

per century information technologies find the firmware file of the equipment of the same Samsung simple enough. The instructions given will tell you in detail how to flash a printer of a common model - ML-2160. It is often possible to order a firmware file from trusted specialists, along with it they will send detailed instructions for firmware with their own hands.

What will be discussed:

Printer Firmware Information

Long-term operation of Samsung office equipment may lead to the need to flash firmware. As a rule, the firmware is tied to the model and serial number of the printer. Information about the firmware of Samsung equipment is easy to find in the public domain, it is enough to know the serial number of the device and the model, for example, ML-2160 or SCX-3400. After the firmware, the equipment will work without interruptions and additional chips. The printer or MFP will no longer be blocked.

Instructions for firmware office equipment

Many ordinary people are wondering how to flash samsung printer at home, because at home there are no necessary tools and desired files. Experts advise to perform several steps in stages. Carefully follow the instructions on how to flash your printer yourself.

Information reports

The first and easiest step in detailed instructions Samsung printer firmware is always the same: you need to request a configuration report. To do this is quite simple. Load two sheets of paper into the printer, be sure to check that the covers are tightly closed. On your Samsung MFP or printer, press and hold the top Print from Screen button ( print screen) within a few seconds. The installed indicator should blink several times, stop and, as soon as it works again, release the button. The report will print.

The next button will help you print a consumables report. To obtain it, you must again hold the print button for a few seconds. In this case, the indicator signal should be different. It will be possible to release after the following sequence of blinking of the indicator: lit up, went out, lit up, went out and began to blink more intensively - release the button.

Firmware version

After the actions taken, the printer will print two reports. Carefully study the contents of the first sheet and look for the following inscriptions: “firmware version” and “machine serial number”. The second report should contain "serial no".

The serial number contains Latin letters and numbers and differs depending on the type of printer or MFP, as well as the manufacturer (Samsung, HP or Xerox).

Finding the firmware file

The necessary data found in the reports should be carefully written off or a sheet scanned. After that, you need to contact specialists with these data, not forgetting to tell the printer model, for example, ML-2160 or SCX-3400. Of course, you can find and download the firmware file yourself on the Internet, but there is no guarantee that there will not be a software glitch that will destroy your printer.

The downloaded or received file must be transferred to a computer to which a Samsung printer or other office equipment is directly connected.

Preparing for the firmware

First of all, of course, you need to connect office equipment to your computer. Regardless of whether it is a printer or an MFP. Connection is made via USB cable. After connecting, you need to wait for the system to notify that it has been determined.

Self firmware

The name of the firmware file will match the name of the printer model. For example, the file might be named like this: FIX_ML2160_V1.01.00.34.

The file itself should be transferred to the printer connection icon, often it looks like this: USBPRNS2.EXE. Do not be afraid of a darkened monitor, as the firmware file is being uploaded directly to the printer. After that, the device reboots itself.

Important! In no case do not turn off the printer yourself, wait until it completes the reboot.

The firmware process takes from 1 to 3 minutes, depending on the model of equipment and the manufacturer (Samsung, HP or Xerox). The printer will automatically enter the operating mode, restoring all settings.

It may be necessary to force the firmware download mode in the ML-2160 model. This is easy to do: turn off the printer from the network, hold down the print screen button and turn on the equipment. Hold the button for three seconds, the indicator should light up. Forced download can be used in case of an incorrect firmware file, or if you need to return the original version.

Shutdown

The last step in Samsung printer firmware is to remove the special chip from the cartridge. In addition to direct extraction, you can seal it with tape or insulating tape.

To end the work, hold down the stop button for a few seconds. The equipment is ready for work, the firmware with your own hands was a success.

Do not forget that finding information on how to flash a Samsung printer is quite simple. But self-firmware can not always be a panacea for software failures. Carefully study the information on how to flash the printer at home before you get started.

In the event of a breakdown of one or another equipment, many wondered which service center to choose. Now the list of companies that are engaged in repair is quite large and does not cease to grow. Therefore, the choice is quite large.

In this article I will try to give some tips on what you need (or do not need) to pay attention to when handing over equipment for repair. After all, the amount of money, time and nerves spent by you directly depends on the right choice.

1. Do not pay attention to the respectability of the premises for receiving equipment, the number of personnel and other trifles. You have to pay rent for the extra square meters, and the reception girls have to pay a salary. So the prices for services need to be somewhat overestimated. Of course, there are exceptions, but they are few. I do not urge to give your favorite laptop or printer to the basement to an incomprehensible person who is both a master, an inspector and a director of a company. But a small firm, in which one, but an intelligent person works at the acceptance, does not need to be swept aside immediately.

2. Specify whether you pay for diagnostics if the master could not repair the device or if you refused to repair it. The requirement to pay for diagnostics in case of failure is quite normal, the master spent his time working with your equipment. For example, I do not charge for diagnostics only if I cannot repair the device or the repair costs more than half the price of a new one.

3. Specify whether you pay for the spare parts ordered by the master in case the item could not be repaired. If yes - run from this service. You should not pay for the errors of the master, just because he did not correctly identify the breakdown and ordered the wrong spare part.

4. It will not be superfluous to inquire about the maximum repair time. Also stipulate that you would be contacted and announced the full cost before the start of the repair. Otherwise, you risk getting a bill, for example, 80% of the price of a new device. And, since the repair is over, it will be very difficult to prove anything.

5. Carefully read the receipt for acceptance for repair. If you have stipulated some conditions, but others are indicated in the receipt, your verbal agreements have no force. Also pay attention to the description of the defect, appearance and device configuration. If something is indicated incorrectly, this will enable the service center to return the device not in the configuration in which you handed it over, with mechanical damage or with another defect. For example, you gave a laptop with a defect "No sound", and the receipt says "Not working". The service center can give you your laptop, which no longer turns on.

6. It will not be superfluous to ask for a list of spare parts and their cost before the repair begins and compare with prices on the net. In this case, a markup of up to 40 percent is allowed. Many parts come out of warranty or may be damaged during installation. You also need to consider shipping costs. Therefore, some margin for the cost of the SC must be left. But if prices differ by 2-3 times - it's worth considering.

You can also look at reviews on the Internet about a particular service or find out which service centres available in your region. For example, drive into the search "Repair of printers in Minsk." Just do not forget, the negative will be necessary. It is necessary to evaluate not the presence of negativity, but its quantity.

In any case - do right choice and good luck to you!

Greetings, dear visitors. Quite often I am asked how to extend the life of a Canon cartridge or print head.

Let me tell you right now, first of all, we are talking about inkjet cartridges for Canon printers. Such as CL-511, PG-510, CL-446, PG-445, CL-441, PG-440 and others. That is, we are talking about ordinary inkjet printers and MFPs that have two cartridges. For example MP280, MP230, MG2440, E404, MG3540 and others. But this also applies to Canon printers using the print head and ink tanks.

Let's see how these printers print. I immediately warn you, I will state the principle of printing in a very simplified way.

The cartridge has an absorber - a sponge in which the ink is located. From this sponge, they are fed into nozzles (nozzles). Nozzles are tubes of very small diameter. Each tube contains one or more thermocouples. During printing, the thermal elements heat up, the ink boils (an air bubble is obtained) and “shoots” onto the paper. Again, I have described very simplistically.

What happens if there is no ink in the nozzles? Thermocouples will still get hot. And the ink in the nozzles is still used as a coolant. Overheating will occur - the tubes (nozzles) are deformed and / or part of the thermoelements will fail.

After that, the cartridge will print poorly in some colors, or will not print at all.

I think the answer to the question "How to extend the life of the cartridge?" obvious - it is necessary to ensure that there is always ink in it.

But what about those who refill cartridges? After all, after the first refueling, it no longer shows the ink level. There is a simple rule. If you need to print something, but you are not sure that you have enough ink - . It will not be worse. And, perhaps, this will save him.

If you expect that thanks to this advice, your cartridge will work forever - then you are mistaken. It will definitely burn. Why? Yes, because, according to the manufacturer, it is disposable (the statement does not apply to printheads using ink tanks). The main task of the manufacturer is to make sure that he is guaranteed to print the ink filled from the factory, and then, as quickly as possible, fails. Yes, the manufacturer wants to do business on consumables, he also wants to eat :)

But hopefully this article will help your cartridge last longer :)
