Dear All, The Ricoh MP C4503 yellow pcu Developer leak at the center of drum as the photo show. we exchange the yellow pcu with another mpc4503 but after few day later the yellow developer leak again.
We check the 1st pcu's developer unit look ok & clean. only the drum got yellow toner/developer at the center. reinstall it to another MPC4503 and no developer leaking after 50 sheets of color printing.
These unit have B/W meter ~ 500k and color meter ~ 10K only.
