If your office prints a steady flow of invoices, forms, statements, reports, shipping paperwork or internal documents, Canon’s imageFORCE 1643 Series is the kind of device worth paying attention to. Rather than trying to be everything to everyone, it focuses on what many workplaces actually need: fast A4 black-and-white printing, strong scanning performance, sensible paper capacity, and security features designed for modern business environments.
Canon positions the range as a compact but capable mono multifunction option for small to medium offices and shared workgroups. In practical terms, that means it is built for places where document output matters every day, but floor space, simplicity and running efficiency still matter too.
Who the imageFORCE 1643 Series is really for
This is not a home printer, and it is not trying to be a creative studio machine either. The imageFORCE 1643 Series makes the most sense for workplaces that are document-heavy and productivity-focused.
That includes settings such as:
- Small to medium businesses with shared printing needs
- Finance, legal and admin teams handling high volumes of black-and-white paperwork
- Reception areas and back offices that need fast scanning and copying
- Schools, healthcare settings and professional services firms that value reliability and security
- Workgroups that want a serious A4 device without moving to a larger A3 footprint
If colour output is not the priority, a strong mono multifunction device like this can often be the more practical and cost-conscious choice.
What stands out most
Fast everyday performance
The imageFORCE 1643 Series prints at up to 43 pages per minute on A4, with duplex output up to 36 images per minute. Canon also quotes scan speeds of up to 100ipm, which makes it a strong fit for offices digitising forms, contracts, delivery paperwork or batches of admin documents throughout the day.
Compact footprint, serious capacity
Although this is an A4 machine, it is not a lightweight entry-level device. Standard paper input is 650 sheets, expandable up to 2,300 sheets with optional paper feeders. That makes it much more suitable for shared office use than a basic desktop printer that constantly needs refilling.
Strong focus on security
Canon places a lot of emphasis on security across this range. Features highlighted include secure print, encrypted PDF support, TLS 1.3, WPA3, IEEE 802.1X, SIEM support, Verify System at Start-up with automatic recovery, and Trellix Embedded Control. For businesses handling sensitive information, that matters just as much as speed.
Usability that suits busy teams
A large 7-inch colour touchscreen, mobile and cloud print support, and the ability to save scanned files in formats including Word and PowerPoint all help make the machine feel designed for real workflows rather than just raw output.
Sustainability improvements
Canon also highlights sustainability improvements, including up to 25% recycled plastic in the build and low energy consumption features such as low melting point toner technology.
imageFORCE 1643 vs imageFORCE 1643F
The range includes two main multifunction variants:
- imageFORCE 1643 – Print, Copy, Scan and Send
- imageFORCE 1643F – Print, Copy, Scan, Send and Fax
For many modern offices, the standard 1643 will be enough. But if your business still relies on fax workflows, the 1643F keeps that functionality in the mix without needing a separate device.

Why this series makes sense in 2026
There is still plenty of focus on digital workflows, cloud storage and paper-light processes, but the reality for many businesses is that documents still move through offices every day. Purchase orders, invoices, dispatch paperwork, internal forms, legal packs, compliance records, staff documents and signed copies all still need to be printed, scanned, copied or securely shared.
That is why a machine like the imageFORCE 1643 Series still has a clear place. It gives teams a serious document hub without pushing them into an oversized device or a more complex setup than they really need.
For offices that want dependable A4 mono output, stronger security, better scan performance and enough paper capacity to avoid constant interruption, this looks like a very sensible addition to Canon’s business lineup.
Final thoughts
The Canon imageFORCE 1643 Series is unlikely to grab attention because it is flashy. It is more interesting than that. It is a business printer built around the real needs of shared office environments: speed, scanning, security, usability and sensible efficiency.
If your business does not need colour, but does need a compact A4 multifunction device that can handle serious daily workloads, the imageFORCE 1643 Series looks like a strong fit.
