Query: Total scam

This printer works great until you get about halfway through the toner cartridge and it keeps giving you a toner low warning and refuses to print. You have to then take the cartridge out, shake it and put it back in. It will do this about every other page. It is a complete scam to make you buy more toner when you don't in fact need it. Unbelievably unethical. Running a printer with low toner does nothing to damage the printer itself, so stopping the printer from printing when the toner is "low" is only to make you buy more of their ink.If you have the opportunity to buy another printer with similar qualities, go with something else. While there may be "fixes" to this toner low issue, it's extremely frustrating when you need to print something and it keeps forcing you to stop because the the toner is low.Read other reviews, they'll reference this issue as well. Extremely frustrating.
