What I understand, you changed the fuse and after changing the fuse, printer is turning ON? If so did you checked the fuse again? If it is blown again then there is a fault in Power Supply Section.

Unlike the inferior Epson cartridges, the Brother printer resets the chip when you refill them.
Follow the installation of fresh cartridge instructions.
The is a lot of help and videos in the bottom link, but this post appears to fix the issue according to Brother, and the link below that from iFixit gives an alternative solution but way more complicated..
Could the DCP-L2540DW be waiting for another page to be scanned for a two-sided document? If it is set for manually copying both sides of a page that is on the scanner glass, press 2 or the down arrow to get the copy to print. See the basic user guide available here: https://support.brother.com/g/b/manualtop.aspx?c=us&lang=en&prod=dcpl2540dw_us_as to find the section to set the copy function to turn off the two-sided option.
If the LCD screen says "out of memory", you need to get faxes and other print jobs out of memory or turn off memory receive. If the LCD screen shows "scan unable", then the scanner mechanism may not be moving properly. Try turning the all-in-one off and unplugging it for a while. If the mechanism is still stuck when the power is connected again, then the unit needs to be repaired or replaced. If it is under warranty (1 year unless you bought the extended protection), contact Brother.

If you have replaced multiple components in your Brother 8510 printer, including the oven unit, laser unit, high voltage board, power board, and drum unit, but are still experiencing faded images, there are a few other potential causes and solutions to consider:
1. Toner Cartridge: Ensure that you are using a genuine and compatible toner cartridge for your Brother 8510. Low-quality or incompatible toner cartridges can result in poor print quality. Try replacing the toner cartridge with a new, genuine Brother cartridge to see if it resolves the issue.
2. Toner Density Settings: Check the toner density settings in the printer's software or control panel. If the density is set too low, it can result in faded or light printouts. Increase the toner density setting to see if it improves the print quality.
3. Cleaning the Corona Wire: The corona wire is responsible for transferring the toner to the paper. If it is dirty or contaminated, it can cause faded prints. Consult your printer's manual for instructions on how to clean the corona wire properly. Be careful when handling the corona wire as it is delicate.
4. Print Settings: Check the print settings on your computer or within the printer's software. Ensure that you are using the appropriate print quality settings and that any power-saving modes are disabled. Adjusting the print settings to a higher quality mode can enhance the print quality.
5. Contact Brother Support: If you have exhausted all the troubleshooting steps and the issue persists, it may be beneficial to reach out to Brother customer support or a qualified printer technician. They can provide further guidance or arrange for a professional inspection and repair of your printer.
Remember to follow the manufacturer's guidelines and safety precautions when working with printers and their components.
If error message still says replace waste toner box, then you need to check the sight glass again. The flag must be horizontal at the bottom of the glass or it is not completely empty.
Personally, I would just have found the correct USB Cable for it. The most likely reason would be that the Router details for the WiFi were not entered correctly. A quick search suggests it might be incorrect drivers. The windows version tends to be important in these questions.

Your Brother printer model 7535's drum may be getting toner powder on it for a number of different reasons.
You might try the following troubleshooting steps:
Make sure the toner cartridge is seated and correctly put in the printer by checking it.
Toner powder may spread on the drum if the toner cartridge is not placed properly.
Cleaning the drum may be necessary if it is unclean or has toner powder on it.
A clean, lint-free cloth should be used to carefully wipe the drum after opening the printer and removing the toner cartridge.
Avoid touching the drum with your fingers as this may leave a fingerprint that can affect print quality.
Replace the drum: The drum may need to be replaced if it is worn out or damaged.
For information on how to change the drum, consult the documentation or manual that came with your printer.
Go at the printer's settings:
Make sure the printer's settings are configured properly for the kind of paper you are using.
Toner powder may spread on the drum if the printer is configured to use heavy or thick paper.
If your Brother GX-8500 electric typewriter is not typing after replacing the ribbon, here are a few things you can try:
Make sure the ribbon is properly installed. Ensure that the ribbon is installed with the correct side facing the platen and that it is threaded properly through the guides.
Check the print wheel. Make sure the print wheel is properly installed and that none of the spokes are bent or damaged. If the print wheel is damaged, it may need to be replaced.
Check the correction tape. If your typewriter has a correction tape, make sure it is installed properly and that it is not jammed or tangled. A faulty correction tape can cause typing issues.
Check the power supply. Make sure the typewriter is properly plugged in and that the power outlet is functioning. You can also try plugging the typewriter into a different outlet.
Try resetting the typewriter. Some typewriters have a reset button or combination of buttons that can be pressed to reset the machine to its default settings. Refer to the user manual or contact Brother customer support for instructions on resetting your specific model.
If none of these solutions work, it's possible that there may be a more serious issue with the typewriter that requires professional repair.
