I'm a homeschool mom on a budget. I print a lot of curriculum. I have a laser printer and buy off-brand toner because it saves me money. I am on my second color laser printer, so I know what I'm doing and have thousands upon thousands of pages worth of experience.My first complaint about this toner is the color. It is too bright. Having tried a variety of of brands, I know the color is never as good as the Brother brand, but is usually fine for the price. This company was my go to for my old printer, because they had the best color. This batch of toner was much brighter than what I had grown to expect from them. But that issue wouldn't have been a big deal if I hadn't had others.The magenta toner ruined everything! I knew there was something wrong with the magenta right away because it added a light pink to every page that went through the printer even the ones without any print. I emailed the company and asked for a replacement, but unfortunately the pink was difficult to capture in photograph (even compared to an unused sheet- see picture), so they didn't think anything was wrong and told me I just needed to clean my slides. If I were a company, I would've needed to order a whole new set, because the pink residue wasn't acceptable and to my knowledge you can't just order one color of off-brand toner.Well, next it turned into spots of magenta on everything. Unfortunately, I had two big printing jobs and kept trying to just clean off the slide as they had suggested to me. Nothing worked. When I was trying yet again, a large amount of magenta just spilled from the toner cartridge and made a huge mess. My thought at the time was not, "take a picture of the mess," it was, "get it out of the printer!" (I don't have a picture, but just imagine the inside of your printer where the cartridges belong with a wide pile of magenta powder and lots of magenta spots over everything else in about a one foot radius.) I couldn't reach everything, but after about 20 minutes detail work, it's not as noticeable. I should also mention that the inside of my vacuum canister is now a bold shade of magenta too. I wrote the company again at this point and explained how it had ruined everything I'd tried to print. They offered a $12 partial refund for the magenta. I went through the majority of the entire toner set (which is clearly not very high yield according to the printer censors) trying to make this magenta work and getting increasing larger amounts of pink all over everything. As a homeschool mom printing curriculum for my own family use, I can get away with ridiculous splotches of pink, but it's not ideal and I will need to reprint all of the non consumable pages, when I get a new set. Seriously though, when you've been in contact with a customer about the same toner and how they've not been pleased with they print quality,what is $12 going to buy to help the situation? I was a long time buyer of this brand for another printer, but I will no longer be supporting this company for my new printer.
