Unfortunately, I don’t think it is. I used to use knock-off toner, but after a firmware update, the printer would no longer recognize those cartridges. Luckily, I had bought them on Amazon, so I just explained the problem to customer service and got a full refund. I still love the printer though.
Wow what does Oman have going on over there?
