Our take
The Canon imageCLASS D340 is a monochrome laser printer and copier rather than a fax machine. Canon documents USB, 120 V operation, a 50-sheet ADF, and up to 15 ppm for both printing and copying. Its reviewed guide does not settle networking, duplex, or recommended monthly volume, so those needs should be matched elsewhere or verified before purchase.
A small office that needs a monochrome printer and copier, can connect by USB, and does not require fax or network sharing..
Look elsewhere if fax, built-in networking, confirmed duplex printing, scanning, or a numeric monthly recommendation is required.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon's U.S. guide identifies a 120 V D340 configuration with printer and copier functions.
- A 50-sheet ADF can feed a stack for copy work.
- The 15 ppm print and copy rating provides a concrete speed reference.
What to weigh up
- The exact D340 is not a fax model, and scan capability is not established by the reviewed guide.
- USB is the documented connection; Wi-Fi and Ethernet are not confirmed.
- Duplex support and recommended monthly workload remain unknown in the saved evidence.

What the features mean for you
Separate the D340 from the related D320
Canon's combined D320/D340 basic guide distinguishes the imageCLASS D340, which is the candidate model considered here. The reviewed U.S. support record and guide identify a 120 V configuration, while neighboring models can have different electrical or paper-handling details. Confirm the D340 nameplate on an offer rather than applying all D320 family facts to it. The D340 combines laser printing and copying, but the reviewed evidence does not support labeling it as a fax machine. Exact identity helps prevent a listing from borrowing capabilities from a different imageCLASS variant.
A printer and copier for paper documents
Canon documents printer and copier operation for the D340. Its 50-sheet automatic document feeder can help when copying several sheets in sequence, reducing the need to place every original separately. The source does not establish a scan-to-computer function, so the MFP profile should be understood as copy capability rather than a promise of a full digital scanning workflow. The unit can suit an office that handles paper originals and needs monochrome copies, provided it does not need fax or network scanning. A separate device may still be necessary for those tasks.
USB sets a direct connection expectation
Canon's guide lists USB for the D340, and no built-in Ethernet or Wi-Fi is confirmed in the reviewed source. This points to a direct-connected computer rather than a standard shareable network printer. A USB arrangement can work for one workstation, but sharing from multiple devices requires an independently confirmed print-sharing setup. Check the available host, driver, and cable before choosing an older model. Do not rely on a seller's generic imageCLASS description to establish that the D340 has network hardware or wireless support.
Do not fill gaps in duplex or monthly guidance
The saved Canon guide does not establish automatic duplex or a separate manual-duplex function for the D340. It also does not provide a recommended monthly volume. Those facts remain unknown rather than borrowing from the related D320 or from another Canon laser model. The 15 ppm rating describes speed, not intended average workload. If frequent two-sided printing or a numerical workload threshold is important, select a model with an exact D340-specific source for that feature or choose an alternative with clearer published guidance.
Verify voltage, feeder, and individual condition
Canon documents 120 V operation and a 50-sheet ADF, but the specification describes a model, not the condition of a particular used machine. Check the voltage label, feeder behavior, copier glass, paper path, USB connection, and print quality. Confirm that the offered device is D340 rather than D320 and ask what supplies and accessories are included. Current drivers, consumables, service, price, and return terms are offer-specific questions. If possible, run a multi-page copy and a print from the intended computer before depending on the unit for regular work.
What else to compare
Compare a networked monochrome MFP if fax, scan-to-computer, or shared access is part of the workflow.
Before you buy
Does the imageCLASS D340 include fax?
No. Canon's D340 guide describes printer and copier functions, not a fax function.
How large is its document feeder?
Canon lists a 50-sheet automatic document feeder for the D340.
What is its recommended monthly volume?
The reviewed Canon guide does not state a comparable recommended monthly range.

The decision
The D340 combines monochrome printing and copying with a 50-sheet feeder, but its USB-only, non-fax role and unknown duplex guidance define its limits.
