Due to running out of C280 black toner, i needed to get a customer going urgently, as the C360 uses the same IU & drum units, i figured it must be the same toner,but the caps are different...so taking a chance, i swapped over the cap from the C280 toner to the C360 toner....have done 2 of these in the last week & both work ok...but if you do swap the caps, make sure that you give the bottles a good shake, otherwise when you remove the cap, you'll spill toner everywhere...it's a 2 min job to swap them...
