Hi, I'm Sudipto. Welcome to JustAnswer. I'm reviewing your question now, and will post back with your reply ASAP
Can you please recheck and let me know the model no. of the printer, because Brother CL61 is the cartridge number and this cartridge is used in many models.
Thanks for providing the model no. can you tell me, if you have tried anything else, except replacing the cartridges to solve the problem.
