How to Identify and Fix Common printer Problems ?

Our sources include academic articles, blog posts, and personal essays from experienced technical support :

Cause 1: The photo bypass tray is located at the wrong position. Cause 4: Paper dust has accumulated on the surface of the paper pick-up rollers. Cause 6: The paper tray was not fully inserted. NOTE: Illustrations shown below are from a representative product and may differ from your Brother machine.
The toner cartridge or the toner cartridge and drum unit assembly is not installed correctly. Remove the toner cartridge and drum unit assembly. Remove the toner cartridge from the drum unit, and reinstall the toner cartridge back in the drum unit.
An Ink cartridge has not been inserted in its slot correctly: If an ink cartridge isn`t fully clicked into its designated slot, the printer can`t detect the new ink cartridge and will display an error message.
Hold each ink cartridge as it would be installed in the machine and locate the black Ink Sensor in the Ink Sensor Window at the top of the cartridge.
Missing colours, streaky prints, smudges and ink blotches are all signs that your printer ink or toner cartridge may be damaged. Some printers will actually warn you if a cartridge is damaged and will refuse to print. This includes HP ink cartridges, Samsung toner cartridges and Canon ink cartridges.
Just above the circuit board on most printer cartridges, you`ll find a small button. You`ve seen these tiny buttons before on cell phones, phone chargers, etc. This is your reset button, and the only way to get in there is either with a paper clip or the tip of a pen (which will leave a tiny ink smudge on the button).
Make sure that the paper is fully inserted into the product. Try printing again. If the issue is not resolved, try loading different brands of paper and different types of paper, one type at a time. Then, try printing again.
Most of the time, people are getting the blank page from their brother printer due to the ink cartridge issue, so you need to assure that your printer has enough ink to print a text on the paper, if it doesn`t have enough ink, you may replace the ink cartridge as well.

An error in the cartridges, the heads clogged by dry ink, a very low level in your consumables, a bad connection between the computer and the printer, a damaged cable, a jam in the print queue…, there are many reasons why your Brother printer may stop printing or print poorly even though you have not jumped the ink …

printer doesnt work
ANSWER : Next time, when the printer ink of your cartridge gets over, get a refillable printer ink. It is an affordable way to reduce the printing cost and to avoid bearing the sky-kissing rates of cartridge replacements. If its is still in warranty then contact seller.
