Good day people. I have an off lease machine, Bizhub C220. Works OK for the most part. Last week, while doing some sequential numbering, just one small spot in red, my magenta toner ran out, replaced it with a full one, and continued on. The run was 2000 sheets. Then a few minutes later, the machine throws a C-2553 code, Abnormally low toner density detected magenta TCR sensor. And I see that the machine is using and dropping an abnormally high amount of Magenta toner, my waste toner box was almost full of just magenta toner, and after maybe 100 sheets, the brand new Magenta toner was almost empty. Is this the sign of the developer on the way out or contaminated? TCR level was 6.5% for magenta. Some fixes say to clean the TCR sensor for the MAgenta color under the Imaging unit. Where is this located?

I'm located in the greater Montreal area. Looking for a technician who could service the machine from time to time. References would be appreciated. Thank you all.

Are you using aftermarket toner? what are life counters of developer units & drums?

Using OEM toner

Todays TCR readings: C- 6.89, M - 3.55, Y- 5.52, K-4.33

Drums are reasonably new, display says to replace, but image is good, toner use on C Y and K are normal.

Its the Mag.

With that low TCR number, is the M dev unit on the way out?

try a toner add cycle? at least to see if it increases or its not adding toner at all.

New Drum and Entwickler Magenta and cleaning up HV Board contacts helps for this error for i-Series. Try worth it
