add toner indication for magenta

[sharpmind]

Maybe you are right with your suggestion. I really appreciate it. But why magenta toner is not detected??This is main problem of the machine.Second, no color output in the test page. After several checking, SC 672 occurs. Weird machine!

Interesting if the pipes are empty or are the blocked ie full then in all probabilty it is the pump clutch that is the issue here. remove the pump flush the clutch out with IPA and does this cure the problem. If the pipe is full then look further down the line ie the dev unit is starved of toner change the clutch pump assembly
