Printer does not recognize it
on May 18, 2012
I bought two toner cartridges based on the good reviews. One review suggested to buy 2 in case one does not work and this was the only one mentioned toner not working. Very sadly both did not work for me. I was too trusting about the reviews so I didn't try the toner right away when received. I waited till the Brother TN450 was completely out (more than 3 months passed after I made the purchase). Therefore, I can't return or replace them because the seller only provided 30 day return policy. Luckily I found on Youtube how to refill the TN450. I followed the refill instruction and dumped the black powder from the non-working OEM one and filled the Brother one. It worked!! So I don't need to throw away the un-compatible ones. It is also cheaper to buy the "powder" and re-fill by myself.
