I have used Monoprice laser ink cartridges for several years in my three home Brother printers and have been pleased with the results until this purchase. The print output is not black and white but lightly printed backgrounds and greyish text. I am disappointed and wondered whether this is just a bad luck draw or to expect more of the same for future purchases.
I've been a Monoprice customer for years, so thought I'd try this toner cartridge on my Brother printer/copier, replacing the 15,000 copy high yield OEM toner. At first I thought the cartridge price and quality was excellent, and I thought I had found a new supplier. But after only 3,000 copies, the print quality started fading to print only gray tones and must be replaced after only 3,600 copies. Not sure if this is an anomaly after reading other reviews, but it's disappointing for my first use.
