Why are there only three cartridges in the black ink conversion kit?
The ink conversion process drains only the black ink channel; the C/M/Y colors are not drained. The three cartridges in the conversion kit are used to close the C/M/Y ink valves during the draining process. However, the process performs an initial fill on the whole ink system after the draining is complete.
