On the screen there is likely an oil can showing, it is a warning. If you touch it with your finger it will display the warning. If it is there it will come up as a "P-XX"

Remove yellow drum and yellow developer unt.
On dev unit check magnet roller for developer loss (lower density, voids) compare with other developer units.
Check yellow toner hooper (is it empty or is it full of toner).

Is customer experienced paged fully covered with yellow?

This might be HV unit problem but also can be caused by bad drum unit(s) or overlife drum unit or even transfer belt unit (overlife) or simply dev units reached end of life (or near).

* Off Topic * @ Synthohol: From where did you get that fancy "Schematics"? It's not in MY Tech Manual. Would love to have such for the BH-C-280 series and the BH-363/423 as well............
