The "Intelligent" Scanner: Deconstructing the Onboard Processing of a 70PPM Workhorse
Update on Nov. 9, 2025, 11:09 a.m.
In any modern “paperless” office, from a medical practice to a law firm, the document scanner is the most critical bottleneck. For decades, scanning was a “dumb” process. A user would feed paper, and the scanner would produce a “dumb” image—often skewed, with missing pages from a multi-feed, or with poor color. This forced an employee to spend hours in “post-processing,” manually rotating pages, deleting blank sheets, and re-scanning jammed documents.
The solution was not just to make the scanner faster. It was to make it smarter.
A new class of “professional” desktop scanners is defined not by its “brawn” (its speed) but by its “brain” (its onboard image processing). To deconstruct this, the RICOH fi-8170 serves as a perfect technical case study.

1. The “Brawn”: The 70PPM, 100-Sheet Engine
First, a professional scanner must have “brawn.” The fi-8170 is engineered for high-volume, “paper-to-digital” workflows.
* 100-Sheet ADF: The 100-page capacity auto document feeder is the “hopper.” It allows an operator to load a large stack of documents and walk away.
* 70PPM / 140IPM: The engine scans at 70 pages per minute. Because it is a duplex (double-sided) scanner that scans both sides in a single pass, it actually captures 140 images per minute (IPM).
As one 5-star user from a law office noted, “This scanner runs at or near its rated 70PPM… Did I mention that it’s fast?” This raw power is what “provides employees to scan documents at a faster speed.”
2. The “Brain”: Deconstructing the “Intelligent” Hardware
This is where the engineering leap occurs. A “dumb” scanner, when faced with a “jam,” just stops. A “smart” scanner is a sensor-driven, robotic-capture device.
Clear Image Capture (CIC)
The fi-8170 doesn’t just use a generic Contact Image Sensor (CIS). It uses RICOH’s Clear Image Capture technology, which is driven by a “proprietary color-matching processor.” This is an onboard “brain” (an ASIC chip) dedicated only to image quality. It performs complex tasks like Auto Deskew, Auto Image Rotation, and Bleed-through Removal in real-time as the paper flies by.
The result? The file that hits your computer is already clean, straight, and color-accurate. It eliminates the manual post-processing step entirely.
Ultrasonic Multi-Feed Detection
This is a critical, high-end hardware feature. A common failure is when two “sticky” (like lightweight carbonless) pages feed through at the same time. A “dumb” scanner won’t notice.
The fi-8170 uses ultrasonic sensors. It sends sound waves through the paper as it feeds.
* If it “hears” one sheet of paper, it continues.
* If it “hears” two sheets stuck together (a “multi-feed”), the sound wave is dampened. The scanner instantly stops and alerts the user.
As one 2-star reviewer, Richard, discovered, this feature is so critical that “no sense paying a lot extra for a special feature” if it’s not turned on. This confirms that this physical sensor is a key B2B value proposition for “scanning large documents” where “we do not miss a page.”

3. The “Workflow”: Deconstructing the B2B Integration
This “smart” hardware is designed to feed into a professional workflow. This is handled by its “pro” driver stack and its connectivity.
The “Driver” Is the Product
A consumer scanner uses a simple app. A “pro” scanner, as one 5-star user, John Willis, noted, is bought for its drivers. The fi-8170‘s support for TWAIN, WIA, ISIS, and SANE is its “killer app.”
* TWAIN/WIA: Allows it to connect to “bazillion new and old programs.”
* ISIS: A high-speed, enterprise-grade driver essential for integrating with complex, expensive Document Management Systems (like Kofax).
* SANE: Ensures it can be used in Linux-based environments.
This universal compatibility means a business is not locked into one software; they are buying a platform.
The “Workflow” Is the Software (PaperStream)
The trade-off for this “pro-level” power is complexity. As user Tim noted, the included “software is somewhat lacking” and “not intuitive.” This is the “prosumer” paradox. The PaperStream Capture software is not a simple “click-to-scan” app. It is a complex profiling tool.
A 5-star reviewer, Discerning Buyer, captured this perfectly. They were frustrated until a Ricoh agent “spent time setting up profiles for categories of commonly scanned items.” This is the intended workflow. The user must “set up… a host of profiles” (e.g., “Invoices,” “Client Records,” “Receipts”) that define the DPI, color, OCR, and “scan-to” destination (e.g., Cloud, SharePoint, SFTP, or a network folder).
Once set up, the 4.3” touchscreen’s “56 customizable shortcuts” become “one-touch” buttons for these complex, pre-defined workflows.

4. The Network vs. USB Bottleneck
Finally, there is the connectivity choice: Ethernet or USB 3.0.
* The Network Use Case: As 5-star user JP noted, the “network port is extremely useful” in a “medical practice where front desk staff can share a scanner.” This reduces hardware costs.
* The “Throughput” Use Case: However, user Newbully made a critical discovery: “USB 3.0 is the best to use. I connected a USB 2.0 cable and the speed difference was very noticeble. Of course I hade to set up the network cable and found out that USB 3.0 is much more efficient.”
This suggests that for maximum speed (e.g., a “purge” scan of 1,000 pages at 600dpi), the direct-attached USB 3.0 connection is superior. The Ethernet port (even if Gigabit) is for convenience and sharing.
Conclusion: A “Work Horse” for Data Integrity
The RICOH fi-8170 is a case study in B2B “intelligent” scanning. Its “brawn” (70PPM engine) is impressive, but its “brain” (onboard image processing, ultrasonic sensors) is what provides the real value. It is not a “plug-and-play” consumer device. It is a powerful, complex “work horse” that, when “set up… with a host of profiles,” transforms a “dumb” paper bottleneck into a fast, reliable, and intelligent digital workflow.
