P27 is a TDS sensor error. You need to check the connectors on you developer unit. Open front cover, push down on copier then lift green handle. remove screw just above toner suppy unit and remove your drum assembly. Next remove your developer unit(two latches hold it in place). your TDS connector is located under your dv unit(you will have to remove the black cover). When finished reinstall drum assembly then turn on copier. If problems persist turn copier on while holding down 47 then press 40 then start.you should hear a motor running (let it run for 1 min.) If you don't try P40 or 01. Turn copier on then back on. If the problems persist I recommend a service tech. your DV or TDS sensor needs to be replaced.
