Our take
The Canon imageCLASS D780 is a legacy monochrome laser device whose documented value is the combination of printing, copying and fax in one substantial desktop unit. Canon lists up to 16 pages per minute, a 500-sheet cassette and a 100-sheet multipurpose tray. Its standard interfaces are parallel and USB, while network use requires a separate adapter. Canon marks the product retired, and the source does not establish automatic duplex or a recommended monthly volume. Those limits make it a fit only when its particular older workflow and local connection still suit the buyer.

Choose another model if you require built-in Wi-Fi or Ethernet, a confirmed automatic duplexer, current manufacturer support, or a published monthly workload recommendation.
Pros & cons
What could work for you, and what to consider before buying.
What works in its favor
- Canon documents printing, copying and fax together, so those basic paper workflows can share one device.
- The 500-sheet cassette and 100-sheet multipurpose tray offer more standard input than a small personal printer.
- The U.S. support page specifies 120 V power and the standard USB and parallel interfaces.
What to weigh up
- Canon identifies the D780 as retired and says product support and content updates are no longer provided.
- Network use needs the optional AXIS1610 adapter; USB or parallel is the documented standard connection.
- Automatic duplex and recommended monthly volume are not established in the reviewed exact-model specification.

What the features mean for you
Print, copy and fax in a legacy workflow
Canon's D780 support page separates the printer, copier and fax specifications. That matters for a small office that still uses telephone fax or makes routine paper copies and wants those tasks at one station. The print speed is listed as up to 16 ppm, a manufacturer rating rather than a promise for every document. The source describes a mature device with old operating-system references, so a buyer should confirm that the host computer and required drivers still work with the exact setup. The page does not document a scan-to-computer workflow, so do not assume one from the multifunction label alone.
The tray arrangement supports more than a short stack
Canon lists a 500-sheet front-loading cassette and a 100-sheet multipurpose tray. This can reduce replenishment during ordinary paper runs and lets a user reserve the multipurpose path for a different paper size or type. The listed capacities are standard model specifications, not evidence about how full or clean a used machine's trays are. The D780 is large and heavy, so placement and access to the tray and rear ports deserve attention before choosing it for a compact desk. A missing recommended monthly range means workload fit should be checked against maintenance history and actual needs rather than inferred from capacity.
Connection is local unless an adapter is fitted
Canon names parallel and USB as the standard interfaces and identifies an AXIS1610 network adapter as optional. A single workstation can use the documented local connection; a shared office should verify that the exact offered unit includes the correct network adapter and that it functions with current network policies. The support page does not confirm built-in Wi-Fi or Ethernet in the base configuration. A seller's broad phrase such as network-ready is not enough to establish which adapter is installed. This is a meaningful limitation if the printer must join a shared queue without extra hardware.
Treat two-sided printing as an open question
The reviewed U.S. specification lists the print method, speed, paper intake, copy functions, fax and interfaces, but it does not identify automatic duplex. That omission should remain an unknown in the finder rather than being filled from a suffix or a generic D780 description. If two-sided output is important, ask for the exact manual or configuration record before buying and confirm the physical duplex path on the unit. For a one-sided routine, this uncertainty may not matter; for recurring packets it can add a manual handling step that changes the best choice.
Retired status makes the individual unit decisive
Canon explicitly labels the D780 retired and says it no longer provides product support or content updates. That does not tell us whether an individual listing is working or what supplies it includes. A buyer considering one should inspect the model plate, test printing, copying and fax with representative jobs, check the tray feed and output path, and verify that toner and service parts are obtainable from a source they trust. These are checks of a particular machine, not claims that the model has been personally tested. If support, a modern operating system or network setup is essential, a current model is a safer comparison point.
What else to compare
Compare a current mono MFP if driver support, built-in networking or confirmed automatic duplex matters more than this model's legacy fax and paper capacity.
Before you buy
Does the D780 include fax?
Yes. Canon's U.S. technical specifications have a separate fax section for the D780, including modem and receiving features.
Can it connect directly to Ethernet or Wi-Fi?
Canon lists parallel and USB as standard and calls the AXIS1610 network adapter optional; built-in Wi-Fi is not established.
Does Canon confirm automatic duplex?
The reviewed exact-model specification does not state automatic duplex, so treat two-sided capability as unknown until the exact unit is documented.

The decision
The D780 remains relevant only for a buyer who specifically values its print, copy and fax combination and can verify the older unit, connection and supplies. Retired support and unknown duplex are decisive trade-offs.
