C309a Service Manual, Exploded diagram

I’m pretty handy with repairs. But a Service Manual, and/or an exploded diagram of the HP C309a would really help.

@lonote53 Is there anything in particular you are trying to repair/replace?

At the far right of the cartridge carrier track, there is a biuld-up of black, tar-like gunk. I fear it may be interfering with the printer’s ability to align the print heads. Mainly I just want to give the printer a good cleaning, without damaging anything.
