Canon laser printer 30 18, after the first powder addition, the printed words became thinner, but they were not clear before powder addition, which was added by Canon after the sale. What is the reason? The quality of the added powder is not good. If you want to have a good effect, you have to buy the original selenium drum. According to the manufacturer's regulations, the machine manufacturer who added powder does not give warranty. You can call the Canon service hotline and ask: The design of the toner cartridge of the 400622666 manufacturer was originally disposable, or it may be that the toner cartridge is used up!

They add powder to you just to make more money. A bucket of powder is only a dozen dollars. They generally charge about 100 yuan for adding powder, and the profit is high. Euphemistically called saving money for you. The original toner cartridge costs more than 300 yuan. If you want a good effect, you have to use the original one, but it's more expensive!
