Hi,
Before losing all hope, this is what I'd do in your place:
If it this the exact same code (361.362) that point the the Yellow LPH subsystem, I'd try to move the Y drum to another slot and reboot. If the code stay the same after reboot, you'll know that a tech will be needed. If the error code change for something else then I'd try to replace the drum before anything else.
regards.
K.
