Do You Really Need an Expensive A3 Scanner?
Many businesses occasionally need to scan larger documents such as engineering drawings, architectural plans, or long reports. However, traditional A3 document scanners are often expensive and bulky, typically costing several thousand dollars.
The good news is that in many cases, you do not actually need a full A3 flatbed scanner. A new category of devices called wide-format sheetfed scanners can scan documents up to A3 width while remaining compact and affordable.
Understanding Scanner Width: A4 vs A3
Most office scanners are designed for A4 paper. This means they can scan documents up to approximately 21 cm wide.
A3 documents are wider and measure approximately 29.7 cm in width.
| Paper Size | Width |
|---|---|
| A4 | 21 cm |
| A3 | 29.7 cm |
Standard A4 scanners cannot capture A3-width documents unless the document is folded or scanned in multiple sections.
What Is a Wide-Format Document Scanner?
A wide-format document scanner is designed to handle documents wider than standard A4 scanners. One example is the Plustek S30 Wide-Format Duplex Document Scanner, which supports scanning up to 30.5 cm wide, making it capable of capturing A3-width documents.
This allows businesses to scan large documents without investing in expensive A3 scanning equipment.
Extra-Long Document Scanning
Another advantage of wide-format scanners is the ability to scan very long documents.
The Plustek S30 supports scanning documents up to 5 metres long, which is far longer than typical office scanners.
This makes it suitable for digitising:
- Engineering drawings
- Construction plans
- Long invoices or receipts
- Medical ECG strip records
- Archive registers
