does it show on the toner meter?

is it a compatible toner?

is the laser lens cover in toner?

did you check to see if the toner/drum contact are clean n not bent?

are there any error codes listed?

how many pages on the machine total?

how many pages on the drums/belt/fuser?

can you do a stop test? is there magenta on the drum/itb?

other than swapping mentioned WHAT HAVE YOU DONE?

we need all pertinent ifNo in the OP SO WE DON'T SPEND weeks PULLING TEETH!
