Ricoh PostScript3 Unit Type M45: Which Ricoh Printers Does It Fit?
If you have a used Ricoh IM 2500, 3000, 3500, 4000, 5000 or 6000 black-and-white MFP and the genuine Adobe PostScript option is missing, the card you need is the PostScript3 Unit Type M45 (EDP code 418889). It is an SD-card-style module that plugs into the controller and unlocks the real Adobe PostScript 3 interpreter on the machine.
Below is the full compatibility list, what the card actually does once installed, and what resellers should know before buying in bulk.

Do not confuse Type M45 with Type M54, M52, M44 or M37 — those are built for other Ricoh generations and are not interchangeable. If you own an IM C2510–C6010 color machine, that one takes Type M52 instead.
What does Type M45 actually do?
- Adds a genuine Adobe PostScript 3 RIP, replacing the machine's default PS3 emulation.
- Complex PDFs, technical drawings and invoices render exactly as designed — no swapped fonts, no shifted logos.
- Machine reports "PostScript3" as installed under User Tools → Machine Features → Option.
- Raises resale value: legal offices, accounting firms and mid-size businesses specifically ask for "PS3 enabled" Ricoh B&W MFPs.
