[CQ] MX5111 color are fading in High coverage long-run

[ben@km]

Hello, we have a couple of MX5111's that run high concentration of colour on output sheets. The machines don't seem to keep up with replenishment of the toner and fall behind on the toner concentration maintained by the machine in the dev mix with resulting "off colour" service calls (Red become Orange).
Anyone know a way to increase the dump of toner up? I've seen on a different post that there is a TB about new style toner pipe. I dont have access to TB from the US only Techtip from Cnd.
