Embedded EFI SendMe: Redefining productivity by increasing efficiency and reducing costs

With touch-screen ease, embedded EFI SendMe - technology in the CX3641 MFP lets users quickly convert paper documents to digital files, edit them in a variety of ways, and share, distribute or store them on or off-site right from the MFP.

SendMe saves time. When a document is scanned, its image appears on the full-color LCD screen, so users don't have to return to their PCs to see the results. The intuitive interface makes it simple to remove borders, change the angle, and select specific sections to cut and paste or simply erase.

The one-stop workflow also means that users can focus on the task through its completion, reducing the types of distractions that can introduce errors and diminish productivity.

SendMe manages documents

  • Scans can be saved in industry-standard digital file formats (PDF, JPEG and TIFF); with the optional OCR (optical character recognition) software, files can be saved as editable and searchable PDFs or Microsoft Word documents enabling users to search scanned documents for words, extract text, and perform document indexing.
  • When a file is ready to distribute, SendMe can send it to network folders, e-mail addresses and FTP sites. The SendMe NetConnect utility can add a hidden text layer to the file (i.e. metadata, in XML or CSV format), making it compatible with many document management and enterprise content management systems.1
  • Users can choose the optimum file size to provide the fastest transmission and best document quality.
  • SendMe works with all leading network infrastructures, including LDAP, Microsoft Active Directory, Microsoft Exchange and Lotus Notes.

And because the user is never separated from the document, the workflow cannot be broken, averting potential security issues.

SendMe saves money.With embedded SendMe software in the CX3641 MFP, there's no need to purchase additional PC software to complete the conversion or editing processes. SendMe is also designated for unlimited users everyone in the department or workgroup can enjoy SendMe advantages without additional costly software licenses. And the technology is so intuitive, so easy to use that minimal training is required to get the best possible results.

Embedded Fiery System 8e: Redefining color management for business color users

The CX3641 MFPis ideal for business color users with an eye for consistent, accurate color output from their office machines. They can take advantage of access to fast, incredibly precise color printing and copying through the embedded EFI Fiery System 8e controller and accompanying software. Yet with all of its advanced technology, the CX3641 MFP is remarkably simple to use. Once IT administrators have established basic profiles and configurations for specific types of color usage and print jobs (see below), end users can:

  • Print from virtually any business software application and get great results even with large files through Smart RIP technology.
  • Get consistent color page to page and job to job.
  • Produce graphic arts-quality documents with ease.
  • Save the time and cost of using internal repro centers or outside print vendors.

High Definition Color technology ensures outstanding business color output

Unmatched print quality
Not only can the CX3641 MFP print and copy faster than most of its competitors, with High Definition Color print technology and 1200 x 1200 dpi print resolution, there is no compromise on output quality.

High Definition (HD) Color Printing technology renders deeper, more saturated colors, finer detail, and more precise toner placement than ordinary color printers. This unique four-part process delivers fast, high-quality printing with breathtaking output, even on standard office paper. It includes:

1. Multi-level LED printheads: systematically control the amount of toner applied to each dot increasing the color intensity. Multilevel LED printheads can achieve 256 levels of intensity, so that crisp image detail is preserved and color fidelity is maximized.

2. Microfine toner: the large color gamut and pigment density of our color toner ensures that printed documents are sharp, crisp and glossy, owing to:

  • Greater dot stability and more precise toner placement
  • Lower levels of graininess and finer detail
  • High-quality gloss finish

3. Single Pass Color - technology: in this process, the paper medium follows a streamlined path, passing beneath four in-line printheads- one each for cyan, magenta, yellow and black (CMYK)- through the fuser, and out to the user. Simple, effective and fast.

4. Printer control system: each printer has software and firmware that provide:

  • Automatic adjustment for optimum print quality
  • Automatic alignment for sharp, clear images every time
  • Auto color checking and matching with Photo Enhance for professional photo-like quality
  • Automatic adjustment for different media weights eliminates manual setting while maintaining the highest quality

Get the most flexibility in your choice of media
With the CX3641 MFP, you can output reams of reports and high-impact presentations with color graphics; brochures on up to 170-lb. index (307 gsm); mailers on waterproof, tear-resistant sheets; transparencies; even attention grabbing banners up to 12.9" by 47.24".

Use standard off-the-shelf media or select your stock from the tested and proven media collection available through your Authorized OKI Printing Solutions MFP Dealer.

Control the ways in which the CX3641 MFP is used and take control of the bottom line.

Increased security for end users and the company
The CX3641 MFP is designed to provide peace of mind. Security features enable users and administrators to:

  • Protect files from hackers through 128-bit encryption on SendMe files.
  • Prevent unsecured connections to servers through IP filtering and port blocking features.
  • Link access restrictions to the company's e-mail directory (LDAP), and require user password authentication.
  • Limit e-mail from the MFP, with requests granted or denied based on entering of valid network passwords.
  • Control access privileges, such as ability to print/copy in color, through assigned Personal Identification Numbers (PINs) and LDAP user authentication.
  • Encrypt electronic documents and latent file images stored on the MFP's hard drive by overwriting the files with multiple passes of random characters.1

Further improve your bottom line
With outstanding reliability, long-lasting consumables and competitively low per-print and -copy costs, the CX3641 MFP delivers cost-effective operation as well as an exceptional return on your investment. You'll control your operating costs by:

  • Supporting one device rather than several
  • Stocking fewer replacement supplies
  • Reducing service interruptions

Even with all of the color-centric benefits included in the CX3641 MFP, users need not pay more if they have black & white print and/or copy requirements. With a low monochrome cost per copy, the CX3641 MFP is an ideal upgrade for existing monochrome MFPs.
