But that sensor can be just a little dirty and if you know how to remove the IBT, you can clean it with a dry cloth. It is located inside the machine, next to the registration assembly under the fuser unit.
"Marks on belt". It is a sensor that read the toner marks on the IBT so can auto adjust color registration.
Hello, I have tried doing an automatic Color Registration from the support menu, but the colors on my VersaLink C7000 laser printer are still misaligned. A thin yellow line is always slightly above a corresponding thin cyan line. For example, when a thin line is printed with color C=100 Y=100, the yellow line falls slightly above the cyan one. This is even more noticeable when the CMYK color is C=50 Y=100, allowing more of the yellow to show through the halftoned cyan line.
How can I do a manual Color Registration adjustment on this printer to vertically realign Cyan and Yellow, since an automatic registration is not doing it.
