mpc4500 adding tonr

[rsyarcia]

I encountered this problem many times with black toner (MP C2500), what I did is just cleaned the host(tube) from the toner to the black dev't unit. The toner tends to get stuck on the host(tube) because on the middle it is elevated. Just try this!!!

I've cleaned out clogged toner supply tubes a few times on the MPC 2500-4500 range.
And I've also had a couple of faulty toner attraction pumps.

NIGHTMARE FAULT .... Turned out the fault is caused by the toner signal from the NVRam not being altered when the new bottle installed.
FIX.. copy NVRam on to SD card. Print SMC report. Print of Non standard data report. Carry out MEMORY ALL CLEAR. Reinstall NON STANDARD settings,( mainly the Scanner settings) as you may have back ground. Time will tell if this has worked.
( some machine just will not have it.) If this is the case turn of toner end detect in sp3 05 ???

I have had to do what Spaceman did also. Engine clear. Machine is f*&^%d afterward, and all settings, init's need to be reloaded and performed (line positioning, color cal., etc.)
