If you regularly work with architectural plans, construction drawings, engineering documents or other oversized originals, there comes a point where a standard office scanner simply is not large enough.
A4 and A3 documents are straightforward to scan, but once you start working with A1 and A0 sizes, the requirements change considerably.
For many businesses, the challenge is not just finding a way to scan larger documents. It is finding a setup that is practical, easy to use and suitable for everyday work.
Large format scanning is the process of turning oversized paper documents into digital files when they are too large for a standard desktop scanner.
This can include:
A 24-inch scanner is generally suitable for A1 documents, while businesses working with A0 plans will usually need a 36-inch scanning solution.
When choosing a machine, it makes sense to think about the largest document you may need to scan, rather than only the size you use most often.
If your business mainly works with A1 drawings, a 24-inch machine can provide a compact and practical solution while still covering a broad range of technical documents.
If you regularly handle A0 plans, a 36-inch scanner gives you the extra width needed to scan the full document without reducing its size, folding it or having to work around the original format.
This can be especially useful for architects, engineers, construction companies and facilities teams that need to store, share or update large plans digitally.
It can also make a big difference when working with older drawings that may only exist as paper copies.
Size is important, but it is not the only factor to consider.
A good large format scanning setup should fit naturally into the way your business already works.
Scan resolution is important if you need to retain fine details, small notes or precise line work.
Scanning speed becomes more relevant if you regularly digitise multiple drawings rather than scanning the occasional document.
Ease of use is also worth considering, especially if several people will be loading and feeding documents through the scanner.
Then there is the physical setup itself.
Some businesses may prefer a dedicated large format scanner, while others will benefit from combining printing, scanning and copying in one machine.
For many workplaces, this is where a multifunction large format printer starts to make sense.
A drawing can be printed for a meeting or site visit, marked up by hand, then scanned back into a digital format once the changes have been made.
The whole process can be handled from one device.
This also reduces the need to find space for separate large format printing and scanning equipment, which can be particularly useful in smaller offices, studios and technical departments.
Canon's latest imagePROGRAF TM-510M and TM-610M are good examples of this type of setup.
Both combine large format printing with a built-in scanner, allowing users to print, scan and copy from a single machine.
The TM-510M is the 24-inch model and is well suited to A1 workflows, while the larger TM-610M provides 36-inch capacity for businesses that need to work with full A0 documents.

Canon already has a long history in scanning technology through its imageFORMULA range, but the TM-510M and TM-610M bring that experience into the imagePROGRAF TM range in a different way.
Previous TM multifunction systems used a separate scanner mounted above the printer.
With the latest models, the scanner is built directly into the machine, creating a cleaner and more straightforward all-in-one setup.
An integrated scanner creates a tidier overall system.
There is no separate scanning unit to assemble and mount, no additional scanner power supply and fewer individual components to manage.
For businesses installing new large format equipment, this can make scanning feel like a natural part of the printing workflow rather than a separate process handled by another device.
For everyday plans, technical drawings and document digitisation, it can help create a smoother workflow from start to finish.
Scanning old drawings is one obvious use, but large format scanning can play a much bigger role in everyday work.
A paper plan can be digitised and emailed to another office.
A marked-up drawing can be scanned and added to a project folder.
Older plans can be saved digitally before the original copies become damaged.
Copies can also be created without repeatedly handling important originals.
For teams that regularly move between digital files and physical drawings, having easy access to A1 or A0 scanning can make the whole process much simpler.
For A1 plans and smaller documents, a 24-inch system is likely to be the most practical choice.
If you regularly work with A0 plans, a 36-inch system is likely to be the most practical choice.
