Our take
The Xerox B315/DNI suits an office that needs more than print output from its shared monochrome device. Xerox documents print, copy, scan and fax, automatic duplex, Wi-Fi and Ethernet, a single-pass duplex document feeder, and up to 42 pages per minute on Letter paper. It also lists a recommended average monthly print volume up to 6,000 pages. This combination supports recurring two-sided documents and multi-page capture without adding a separate scanner. The workload figure is an upper recommendation rather than a complete range, and a printer-only desk may not need the MFP’s extra functions.
A small or midsize office that needs fax, two-sided output and networked document capture from one monochrome machine..
Skip it if you need color, only occasional direct printing, or a documented lower-to-upper monthly range for precise volume matching.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Xerox documents print, copy, scan and fax for the exact B315/DNI.
- Automatic duplex output and a single-pass duplex ADF reduce two separate handling steps.
- Wi-Fi and Ethernet are both listed as standard connections.
What to weigh up
- The recommended average volume is given as up to 6,000 pages, without a lower range bound.
- A multifunction unit adds features and setup steps that a print-only desk may not need.
- The headline 42 ppm rating does not predict each scan, copy or print job's actual time.

What the features mean for you
One machine for monochrome print and document work
Xerox identifies the B315 as a multifunction model that prints, copies, scans and faxes in black and white. It can consolidate routine forms, correspondence and scan-to-network tasks where a separate copier is not already available. Its functions are broader than a print-only model, but buyers should confirm the office will actually use them; adding an MFP does not automatically simplify a workflow if staff already have a managed document system. Xerox describes fax features on the exact B315, so the DNI listing fits a fax-required workflow rather than relying on a neighboring printer variant.
Automatic duplex extends beyond printing
The B315 supports automatic two-sided print jobs. Xerox also specifies a single-pass duplex document feeder, which reads both sides of an original during a scan instead of asking someone to flip each page manually. Those are distinct capabilities: the first affects finished printouts, and the second affects copying or scanning incoming paper. The feeder is rated up to 50 sheets and supports multipage originals. This combination is useful for offices handling double-sided forms or reports, though document alignment, file naming and destination rules still need to be configured by the people who manage the workflow.
Speed and monthly guidance describe an office workload
Xerox rates the B315 up to 42 pages per minute for one-sided Letter printing and gives a recommended average monthly print volume up to 6,000 pages. The recommendation is separate from the 80,000-page duty-cycle maximum; the maximum should not be used as the regular workload target. A team can compare its expected monthly output with the 6,000-page recommendation, but the source does not provide a lower endpoint for a range. The speed figure is a rated print result, not a claim that every mixed scan, fax or copy job finishes at that rate.
Wi-Fi and Ethernet cover flexible placements
Xerox lists wireless 802.11 networking and Ethernet for the B315/DNI. Wi-Fi can make installation easier when a cable route is inconvenient, while Ethernet may fit a managed office network. The device also supports mobile printing services, but a buyer still needs a compatible network, client software and suitable security configuration. In a shared environment, administrators should decide whether users print over Wi-Fi or wired Ethernet and control access to scans and fax data. Those setup questions matter because this is an MFP handling more sensitive document flows than a stand-alone printer.
Paper handling and workload should fit the team
Xerox lists 350 standard input sheets split between a 250-sheet main tray and a 100-sheet multipurpose feeder; an additional tray is optional. The multipurpose slot supports different media and sizes, while the main tray covers routine replenishment. That standard capacity can help a small group avoid frequent refills, but it is not unlimited and does not imply every paper type is automatically selected correctly. The 6,000-page recommended average is an upper guidance point, not proof of any particular monthly cost. Check expected use, toner planning and the exact tray configuration independently.
What else to compare
Choose a print-only mono printer for a simpler queue, or a color MFP if documents need color output as well as fax and scanning.
Before you buy
Does the B315/DNI include fax?
Yes. Xerox lists fax as a standard function for the B315 multifunction printer, alongside print, copy and scan.
Can it scan both sides of an original automatically?
Xerox specifies a single-pass duplex document feeder for the B315, supporting two-sided document capture without manual page flipping.
Is 6,000 pages a monthly duty-cycle maximum?
No. Xerox calls it recommended average monthly print volume up to 6,000; the duty-cycle maximum is a separate, higher figure.

The decision
The B315/DNI is a versatile mono document hub with network options and two-sided output and capture. Its MFP size and open-ended volume guidance are the main trade-offs.
