Paper is jammed inside my Brother Wireless Color Laser MFC-L3750CDW printer. How to fix this issue?

No matter what the cause of the paper jam is, it’s important to know how to fix it. There are several solutions that Brother printer support can offer depending on the type of paper jam you have. The LCD will display a message telling you which side the paper is sticking to the front, the back, or both.

Before you begin troubleshooting, unplug your printer from the power supply. You should wait until the printer cools down before you touch the print head or inspect the printer’s interior.

These steps should be followed if the paper is stuck to the front.

1. The paper tray should be removed from the printer. Do not leave the paper support unattended.

2. Slowly take out the jammed paper.

3. Lift the jammed paper from under the jam clear flap and take it out.

4. You should also check for jammed paper areas in the printer, such as the scanner cover.

5. After you have removed all jammed paper, plug it back in the socket to check if the error message is no longer being displayed.

Here’s how to get rid of stuck paper at the back.

  • Remove the Brother printer’s back cover.
  • Remove the jammed paper carefully.
  • Cover it and verify that you have done it correctly.
  • You can see the inside of your printer to find any paper left over.
  • Reconnect the printer to the outlet and verify that it is working.

Follow the steps above if the jammed paper is on both sides. First, remove jammed paper from both the front and back. Next, check the printer’s interior. You should make sure that there is no paper left under the printer head. However, you must be careful not to get ink onto your clothes.

How to clean your Brother Wireless Color Laser MFC-L3750CDW printer? 

 a. choose the Ink option from the screen of the printer.

Press the Ink key on your printer if it is present. To select Ink, open Menu and press the OK and arrow buttons. To use a touchscreen printer, you can either choose Ink from the screen or look for a square symbol that has black, yellow, and blue lines. This is the Ink Indicator. The black ink or the color ink can be cleaned, or both.

b. Choose Cleaning to conduct a cleaning cycle.

If something is not right, this is the best way to clean your printer. It will only take the printer a few minutes for old ink to be removed from the print head. This will result in cleaner prints. A cleaning cycle may be necessary if your print jobs appear sloppy or smudged.

c. While the cleaning cycle progresses, leave the printer alone.

It takes only a few minutes to complete the cleaning cycle. You won’t have any printing or other options. The cleaning cycle will continue for a few minutes, so don’t unplug it. After cleaning, the printer will return to its home screen and be ready to print.

d. Print a single-page document.

Print a single page to test whether the cleaning was successful. You should check it for any smudges. If you have cleaned the ink in color, you should print it in color. If your printing is still not perfect, you might need to do another cleaning cycle or unclog any print head nozzles.

e. You can do up to four cleaning cycles at a time.

You may need to do more than one cleaning cycle in order to achieve the best results. You should not run more than four cycles at a time. This can cause the ink to start drawing out of the cartridges making cleaning less efficient and cost-effective. Try printing 10 pages to check if the printer is still not working after several cleaning cycles.

What is the default password for my Brother network card, BRAdmin, Remote Setup, or Web-Based Management?

To manage all the machine settings of your printer, your default login password is either “initpass”. And, the password that is located on either bottom or back of your printer is preceded by “Pwd”.

I print mainly black and white documents. How can I stop the life of my color toner cartridges from decreasing when I print?

First of all, change the print setting to Mono mode. By default, the driver for printing attempts to determine what kind of documents are black and white, by searching for information about color when you submit an order for printing. The printer driver can then determine what toner cartridges are required. Sometimes, documents can have colored information, even if the document appears white and black document (for example, areas of grey are actually an amalgamation of colors). If the printer driver recognizes the presence of color in your document, it will make use of the toner cartridges in all four for printing.

It is possible to alter settings in the driver of your printer to ensure that the machine treats every document as if only comprised of black and white information. This will stop the life span of your cartridges for color from reducing as you print.
