Fix Ricoh MP C6004 Paper Jams

My Ricoh MP C6004 has started jamming almost every time I print in black-and-white. The sheets stop inside the machine, right around the toner / fuser section, so I suspect the feed path or fuser rollers need attention—possibly a pickup clutch, worn rollers, or a sensor giving false feedback.

I need a technician who knows this model inside out to inspect, diagnose, and eliminate the jam source, then test the machine until it runs a full stack smoothly. Replacement parts (rollers, sensors, fuser parts) can be billed separately once we confirm what is required; I’m happy to approve them quickly so the fix isn’t delayed.

Please outline how soon you can be onsite, your experience with Ricoh colour MFPs—especially the MP C6004 or similar—and what checks you’ll perform before and after the repair. A short post-service report confirming jam-free operation will complete the job.
