IM C4510 / C5510 / C6010
Smart Operation Panel (SOP) 2.5 · GW+ controller · 45 / 55 / 60 ppm color
This is the current color A3 family in the field. SOP 2.5, GW+ controller, ARMS-ready.
Field notes
Models
Unit locations, key SP numbers, and family notes. This is not the official Ricoh service book — screw counts and subcodes still live in the book for that serial.
IM C (current color A3)
IM C3010 / C3510
Smart Operation Panel (SOP) 2.5 · GW+ controller · 30 / 35 ppm color
Same architecture as C4510 at a lower process speed. SP map and SC meanings carry over.
IM C (current color A3)
IM C2010 / C2510
Smart Operation Panel (SOP) 2.x · GW+ controller · 20 / 25 ppm color
Smaller IM C. Same SOP/GW+ habits as C4510.
IM (current B&W A3)
IM 2500 / 3500 / 4000 / 5000 / 6000
Smart Operation Panel (SOP) 2.x · GW+ controller · 25–60 ppm B&W
Mono IM family. Fusing SCs 541–547 still apply. No color process control — ID sensor work is simpler.
MP C Gen 4
MP C4504 / C5504 / C6004
SOP 1.x / 2.0 (depending on dash and upgrade) · GW controller · 45 / 55 / 60 ppm color
Previous-generation color A3. Still everywhere. SC map is close to IM C; firmware packages are not interchangeable with IM C.
MP C Gen 3
MP C3003 / C3503 / C4503 / C5503 / C6003
SOP or classic (by option) · GW controller · 30–60 ppm color
Gen 3 color. Same 541–547 fusing family. Polygon / laser 201–220 still apply.
Pro production color
Pro C5200 / C5210
SOP (production UI) · EFI / GW hybrid depending on config · 65 / 80 ppm color production
Production engine. SC numbers overlap office machines but the FRUs and SP numbers do not. Use the Pro FSM.
