TCR Toner Supply

[Synaux]

Can someone define "auxiliary supply" and/or "reference value" of toner for me?
Is auxiliary supply simply the just the the sub hopper? Or does this actually put more toner in the developing section changing the T/C ratio too?

Manual states the following for TCR Toner Supply:

To adjust the set T/C level by replenishing an auxiliary supply of toner when a low ID
occurs due to a lowered T/C after large numbers of prints have been made of origi-
nals having a high image density.
...
These sequences are repeated up to a maximum of four times until the toner density
reaches the reference value. If the toner density is found to be higher than the refer-
ence value, only a developer agitation sequence is carried out.

To me, it is adding toner to achieve correct TCR, unless the level is too high... then it just stirs it.

As far as I know what Craig says it just takes it from the cartridge to increase to the tcr level for that machine, around 7 to 8 %. The language used does make it sound more complicated though.

If I know my Japinglish as well as I think I do, "auxiliary supply' is actually the toner cartridge. "Reference value" is the ideal T/C ratio.
