Low toner warning? Are toner errors causing you problems? Is your laser printer really running low on toner, or is the low toner warning premature?
Find out by removing the toner and gently shaking it to see if it is actually low. If the toner has stuck to the walls, shaking it will distribute the powder more evenly. This may remove the low toner warning. If you are looking for a way to fix a toner error in your Brother printer, shaking the toner cartridge a few times may be the solution.
If the cartridge is low on toner and you are disappointed at how quickly it ran out, consider investing in high-yield toners, which contain more toner and last longer. For comparison, the HP 37A has a yield of 11,000 pages, the HP 37X has a yield of 25,000 pages, and the HP 37Y has a yield of 41,000 pages.
