brother printer lcd screen blank made in china

Verify the power cord is connected to the back of the machine and the AC power outlet. If the power cord is connected to a surge protector or power switch, remove the cord from the device and connect it directly to the outlet. This is for testing purposes. Removing the device assists in determining if the issue is related to the device or the Brother machine.

Verify the machine is powered ON. The Brother machine has an ON/OFF button located on control panel of the machine. If machine is OFF, the display will be blank.

If the display is still blank, try to tilt or move up or down the LCD display and also try a different known working electrical outlet at your location.

4. When the screen is blank but power LED light is on, this is a sign the firmware has been corrupted. This can happen if power or network connection is interrupted before the end of the firmware update. The firmware can be recovered provided the printer is connected to a computer via printer USB cable and the computer shows the printer is connected.

My LCD screen is shown blank without any single word display on the screen, it still can print if the printer network can be set to proper wifi id. But, in this case the LCD screen is blank and showing nothing, so i can not set to any wifi id at all.

1. The Brother machine has an ON/OFF button located on the top left side of the machine above the button labeled WiFi. Verify the machine is powered ON.

NOTE: Due to the design of the control panel display, looking at display from certain angles can cause the display to appear blank or light. Stand where you can look at the machine display at a 45 degree angle.

5. If you are having difficulty reading the information displayed on the LCD or it"s too light, try changing the contrast setting. Adjusting the contrast will give the LCD a sharper and more vivid appearance.

Have you ever encountered a situation where the Brother printer says no toner after replacing toner cartridge? If so, you have come to the right place. This blog will introduce you in detail the reasons for the "no toner" error and how to deal with it. Please look down patiently.

Usually, no toner error in Brother printer is mainly caused by four reasons. Before we explain why, we have to mention the changes to Brother toner cartridges. If you are a loyal Brother printer user, you must know that Brother toner cartridges have no chips before 2017. And this does not affect the normal use of the toner cartridges.

In 2017, Brother released the first series of laser toner cartridges with IC chips. They are Brother TN-730,  Brother TN-760 and Brother TN-770 toner cartridges. One year later, Brother released the second series of chipped toner cartridges -Brother TN223 andBrother TN227 toner cartridges. That is, from then on, a new error message “No Toner” began to appear on client"s printers. And it is those small toner chips that cause the no toner error in Brother printers.

For Brother toner cartridge with a chip, the chip has become the key for Brother printer to recognize the toner cartridge. Like a lock, you need a key to open it. If your printer can not detect the chip, your printer will not recognize the toner cartridge. Even if your toner cartridge is full, it will not work. That"s why Brother printer says no toner but there is a new toner just installed. Now let’s explain how no toner error occur.

When the printer is running and printing, the toner cartridge driven by the supply roller might lead to the separation of the chip and the printer probe. Then the printer can not detect the chip, which causes no toner error.

When the toner cartridge comes with no chip or an incompatible chip, your printer will not recognize it and display no toner error. An incompatible chip may be due to the wrong chip installed, a damaged chip, or a printer firmware upgrade.

When there are stains, oxidation, gum or other foreign objects on the surface of the chip, the printer probe and the chip may have poor contact, causing the printer to fail to recognize the toner cartridge and display no toner error.

When the printer probe is deformed or damaged, the printer will not detect the chip even if everything is good. So the new toner can not be recognized. And the printer gives a no toner message.

1. Open the printer cover → Close the printer cover → Wait few seconds till the printer finishes running and check whether the printer is back to normal.

2. Open the printer cover → Remove the toner cartridge with drum unit → Reinstall them back to the printer → Close the printer front cover → Check whether the printer returns to normal.

3. Press and hold the “Power” button to turn off the printer power → Wait 3 to 4 seconds → Turn on the printer again → Observe whether the printer returns to normal.

1. Open the printer cover and check whether the chip coding model is consistent with the machine. (This action is only recommended for distributors with professional printing knowledge.)

If you can clearly see four clear scratch marks (as shown on picture ⑧ below) on the chip surface, that means the chip and the printer probe are in normal contact.

No scratch marks represents a poor contact between the chip and the probe and the probe may be deformed or damaged. You need to replace the probe (replace it yourself or contact Brother or 3rd party printer maintenance service for help) and observe whether the printer returns to normal.

The above methods are summarized by our engineers after repeated verification. They can help most printer users who use original and third-party Brother ink cartridges and toner cartridges to fix the no toner error with a high probability. When your printer displays a “No Toner” error, you can try to fix it by yourself according to the above methods. If the error cannot be resolved in the end, you can contact your toner cartridge supplier for a refund or replacement. We believe that if you buy the cartridge from a reputable toner cartridge supplier, they will surely provide you with satisfactory service.

"No Toner" error is a chip related issue. While "Low Toner" message has nothing to do with the chip. This is because Brother toner chip does not have the function of counting toner level. It is only equipped to make your printer recognize the toner cartridge.

Sometimes Brother printer will still say "Low Toner", "Replace Toner" or "Toner Empty" after installing a new toner or drum unit. The possible reason is that the printer failed to reset the counting gear on the toner cartridge. You need to manually reset the toner cartridge in order to make it work as a full new toner. By the way, if you get the Replace Toner error message, you can check Brother Printer Replace Toner Override.

Steps to reset toner: Open the front cover of the printer → On the control panel, press and hold the "Return" and Cancel "X" buttons for 2 seconds → Press the "Return" button again to enter the reset menu → Scroll through the menu to select color toner you want to reset → Press “Yes" to confirm reset → The toner level should be reset. Check whether the "Low Toner", "Replace Toner" or "Toner Empty" message is disappeared.

Please note that the first letter "K" "C" "M" "Y" on the reset menu represent four toner colors, black cyan magenta yellow. The following three letters "TNR" represent toner cartridge. And the last two or three letters represent toner yield. "STD" represents standard capacity or standard yield. And "HC" stands for high capacity or high yield. For example, if you want to reset standard yield Brother TN-223BK black toner cartridge, you need to select "K. TNR-STD" (As shown in picture ④ below).

Till now, Brother printer doesn"t require a chip on drum unit. Brother drum unit is the key component for your printer to turn the toner powder to text or image. When the print text or image quality drops, you need to replace the drum unit or clean the corona wire to improve the print quality.

The printer shown in the pictures is Brother MFC-L3770CDW. It"s the most popular Brother color laser printer in the market in 2022. So, we use it to show you how to remove "No Toner" error message in Brother printer. If you are using this printer, you can clear the no toner error message by following the steps in this blog completely. If you are using other Brother printers, you can also try the same methods.

Locate the chip. It’s a tiny green circuit board about the quarter of the size of a postage stamp. They are often located on the front or bottom of your printer cartridge.

Clearing the memory can give you a more accurate idea of your printer’s ink levels, the number of pages still available to print, and other valuable printing information.

Don’t make the same mistake with your printer’s ink levels. (If you stain your hands or clothes while refilling, turn that frown upside down! Here’s how to clean up!)

Shake your cartridge. The first thing you should try with an HP LaserJet cartridge that’s supposedly empty. This old-school trick will free up the toner particles that are stuck to the inside walls and nooks. After you mount it back to your printer, it may register it as full. You may need to deactivate the ink-saving mode for the printer to detect toner levels properly.

Install an HP chip to a replacement cartridge. This requires some fine motor skills and good tools. You’ll also possibly need to turn off toner level monitoring on the printer.

Get an aftermarket chip for a refilled cartridge. The majority of modern HP toner cartridges are equipped with a small chip that communicates toner levels to the printer.

Canon printers have thermal printheads. The ink actually cools the print heads down, and if you run empty cartridges the print heads can overheat and get damaged.

So, if you replace and remove the four Canon cartridges, and, on the fifth attempt, install a newly refilled cartridge, the printer should accept the cartridge, and ink levels should read as full.

Another warning will pop up on the printer’s screen detailing that you are using refilled or third-party cartridges and may void the printer’s warranty.

Each time you install a refilled or third-party cartridge you will need to follow the on-screen instructions to disable the Lexmark ink monitoring software.

Close your eyes, take a deep breath, and stop expecting printers to “just work” because that would make sense in a world where a touchscreen supercomputer fits in your shirt pocket. Like most things in life that you have no control over, you’ll be happier if you accept printers for the janky money pits that they really are.

Most of you are going to hate something about any printer that you buy, and there’s nothing you can do about it. Instead of fighting it, try to reframe the issue in your mind: You’re not buying a printer because you’re supposed to have one at home. You’re buying a printer because it’s (just barely) less inconvenient than going to a copy center.Make peace with the error message. (Scene from Office Space.)

Unfortunately, we can’t solve all of these problems. But our years of experience covering these apparent boxes of junk give us a better understanding of why they exist. Here are some other general truths that you may have never considered (or willingly ignore when you feel like throwing a tantrum about your printer). Assume that these apply to all printers from all manufacturers unless we say otherwise:Your printer is worth a lot more than you’re paying for it. Seriously, there is some amazingly complicated technology in your printer, including the printheads, the ink, and the mapping software. You take your printer for granted, but that box can cover a piece of paper in millions of dots of precisely located, color-matched ink in a few seconds. You’re probably buying the printer for the cost of parts and distribution, which means the manufacturer is effectively subsidizing the thing on the premise that they’ll recoup their research and development costs (and the rest of their overhead) from your ink purchases.

You should not expect a good experience if you use knockoff ink cartridges. See above. Part of R&D is designing ink to have the right physical properties to work with the printheads. Knockoff ink might not have those properties, and, as a result, may not work very well. Also, as we learned recently, most inkjet printers designed for home use actually have the printhead built into the cartridge itself. There is no permanent printhead in most cheap printers. So you might be buying crap ink and a crap printhead. And if you try to refill a genuine cartridge with knockoff ink, you’re probably putting subpar ink into a container with a burnt-out printhead.

Also, back to the subsidy thing. We’ve read that some manufacturers purposely design their printers to basically shut down if you try to use third-party cartridges. You may not like it, but from their perspective, they’re protecting their investment in their "ink futures," which subsidizes their dirt-cheap hardware.

Knockoff toner cartridges, on the other hand, are okay! Toner is just an electrostatically charged powder (part polymer, part carbon), and the cartridge itself is just a simple plastic container. There are no fancy printheads or circuitry. Manufacturers don’t fight as hard to protect toner cartridges because there’s not a lot of intellectual property in these things. However, they tend to charge a higher markup on the printers themselves to make up for the cheaper toner costs.

If an ink cartridge is missing, you shouldn’t expect your printer to print, and it may not even scan. Some models will still do either or both, many will not. Yeah, it feels like a shakedown when they employ this stand-and-deliver style of ink management, but it’s not uncommon across the industry.

If your home network is more complex than just a modem, a router, and your PC, there’s a reasonable chance that you’ll run into network connectivity problems. There’s not a good reason for this, but the state of networking in the printer industry is abysmal. A printer that works well in one network might need five hours of troubleshooting in another. Unfortunately, this means we can’t say for certain that any given printer will definitely work well on your home network.

At some point you’ll need to manually download new drivers for your printer when you update your operating system. Yeah, this should happen automatically, but it usually doesn’t. Some companies are better than others at issuing new drivers in a timely manner. In our experience, Brother is very diligent and Canon is the most likely to leave behind printers that are more than a couple of years old.

Basically, printers are a dismal product category. But doesn’t it feel better to know why? With that in mind, we realize you still need to use them now and then, and thus we still spend dozens of hours researching and testing in order to make a few recommendations for printers that rise above the (admittedly low) bar:

If you just need something to put words on paper, then simpler is better. You want a cheap laser printer. This thing will cost less than $100 to buy and less than 2¢ per page to operate and can take care of any black-and-white printing you need. Because it’s a laser printer, it uses toner instead of ink, which has two benefits: The toner cartridge will never dry out and become ineffective no matter how infrequently you print, and you can safely use cheaper, third-party toner if you want to save money. However, because it prints in black-and-white only, you’ll still have to make a trip to the copy center for color prints. And the LCD screens on these printers tend to be small and hard to navigate. But for most people that’s still preferable to being unable to print your black-and-white tax returns because your cyan cartridge dried up.

If you need more out of your printer, look into getting an all-in-one inkjet printer. These are best suited for home offices that occasionally use color printing, scanning, copying, or faxing, but don’t require any particular one of these tasks on a daily basis (CPAs need not apply). Like the cheap laser printer, an all-in-one inkjet printer is also affordable up front (less than $200) and cheap to operate (expect 2¢ to 4¢ per page for black-and-white, 7¢ to 10¢ per page for color). However, unlike a laser printer, you have to use the ink regularly or lose it, though these printers automatically perform periodic purges to keep their nozzles clean and ready to print.

Those two printer types should cover most home users, but if what we currently recommend does not seem like it’s going to fit your needs, we suggest that you check out the libraries of individual printer reviews at Computer Shopper and Consumer Reports (subscription required for the latter). These are the most thorough professional sources of information about this category. But you must also read the user reviews of any printer that you think you want to buy. Some printers may test well in controlled settings when used by experienced testers, but fail the take-home test. User reviews considered in the aggregate will alert you to trends in long-term reliability, and individual reviews can reveal a lot of little details that the pro reviews sometimes overlook: poorly written owner’s manuals, whether it jams on card stock, the fax machine doesn’t work, etc.

Brother’s color inkjet multifunction printer (MFP), the MFC-6490CW, adds wide-format printing capability to an already long list of functions. Unfortunately, extremely slow performance is the tradeoff.

The control panel is mostly easy to understand. A 3.3-inch, color LCD shows menu items, photo images, and other info; it also divides fax buttons on the left from major-function and navigation buttons on the right--all labeled clearly. Our one quibble: It’s sometimes unclear which button you use to back out of a menu.

Ink costs are very fair. Brother ships the unit with high-yield cartridges to compensate for the ink typically lost during the initialization process. The 900-page black (K) cartridge costs $31.49 to replace, or 3.5 cents per page. The 750-page cyan (C), magenta (M), and yellow (Y) cartridges each cost $16.99, or 2.3 cents per color, per page. A page with all four colors would cost an economical 10.3 cents. Standard-size ink costs are average. One oddity: None of the ink cartridges are keyed; you can put them in the wrong slot. The unit performs normally anyway, but we’re surprised at this oversight.

The MFC-6490CW’s subpar performance overshadows its many nice attributes. In our tests, it did everything slowly: Plain text exited at a snail’s pace of 5.7 pages per minute (ppm), while the best graphics speed was just 2.4 ppm. Even its scanning and copying speeds were far slower than average. Wide-format output would take even longer. On plain paper, text looked fuzzy and charcoal-like instead of black, while photos looked dull and grainy. Brother’s own photo papers improved photo quality considerably.

Brother’s MFC-6490CW is hobbled by its lackluster speed and variable print quality. If you really need wide-format printing, check out options such as HP’s OfficeJet 7000 (a stand-alone inkjet), which is faster and has better print quality.

When a Brother Printer has a status of "Offline," it is not electronically connected to other devices, such as a laptop or desktop; when your printer is "Online," it is able to connect to other devices. A connection to other devices is necessary, as the printer must receive information from other devices in order to print materials. Your Brother Printer could be listed as "Offline" because it is not turned on, it has errors such as empty toner, it is not set as the default printer or its USB cord or its Network have a connection problem.

Printer Not Turned On Your Brother Printer could be listed as "Offline" because it is not turned on. Even if your printer is connected to your computer via USB, your computer will not recognize any connection if the printer is turned off. Brother reccomends checking the printer"s LCD screen; if it is blank, then the printer may not be powered on. Make sure the printer is plugged into an electrical outlet, the outlet is working and all switches are turned to the "On" setting.

Printer Error Your Brother Printer could be listed as "Offline" if it is experiencing errors such as "Toner Empty" or "Paper Jam," both of which would prevent printing. Brother recommends checking the printer"s LCD screen for any possible error messages. If you see an error message, attempt to remedy the error before checking the printer"s online status again.

Printer not the Default Printer Your Brother printer can be "Offline" if it is not set as the default printer on your computer. A default printer is the printer your laptop or computer automatically sends a print job (unless you specify otherwise) when you click "Print." If your Brother printer is not the default, your computer may be trying to connect to a different printer. You can make your printer the default in your computer"s "Devices" section. If it is not listed as a device in the devices section, you must re-install the printer driver from a CD-ROM or Brother"s website.

USB Cable or Network Problem Your Brother printer can also be listed as "Offline" if its connection is faulty. If you connect to your printer via a USB cable, the cable could have something wrong with its hardware; Brother recommends USB cables that have twisted pair wiring, are shielded and are not more than 6 feet long. If you connect to your printer via a network, the network could be down or firewall-protected; Brother recommends checking your network"s router or hub, checking your computer"s firewall setting to make sure it does not block the network connection and running network connection diagnostics.
