How to Scan on a Scanner: A Practical Setup Guide for Documents
A thorough guide to scanning on a scanner, covering hardware choice, document prep, optimal settings, OCR readiness, and best practices for clean, searchable digital archives.
If you want to turn paper into digital copies quickly, this guide shows you how to scan on a scanner with clear steps, essential settings, and practical tips. According to Scanner Check, choosing the right hardware and keeping glass clean dramatically improves results. By following the steps here, you will produce crisp images, OCR friendly PDFs, and organized archives.
Understanding the basics of scanning with a scanner
Scanning is the process of converting a physical page into a digital image. A flatbed or sheet fed scanner uses a light source and a sensor to capture light reflected from the page as it passes under the glass. The resulting file is a raster image that can be saved as PDF, JPEG, or TIFF. When you plan to scan for documents, choose color mode, resolution, and file format with your end goal in mind. For text heavy documents, OCR enabled workflows and moderate DPI around 200–300 are usually sufficient; for detailed images, graphs, or forms with fine print, 300–600 DPI often yields crisper text and better OCR results. If your aim is searchable content, enable OCR and save as searchable PDFs. Most scanners support TWAIN or WIA drivers, which let you control scanning directly from software, preview pages, crop margins, and adjust brightness. In this how to scan on a scanner guide, we cover practical steps, recommended settings, and common mistakes to avoid.

Understanding the basics of scanning with a scanner
Tools & Materials
- Scanner with TWAIN/WIA compatibility(Prefer a model with a clean glass surface and reliable drivers for your OS)
- Original documents(No staples; avoid wrinkled pages; remove heavy folds)
- Computer or tablet with scanning software(TWAIN/WIA compatible software; OCR-capable if possible)
- Connectivity options(USB cable or network connection; ensure drivers are up to date)
- Cleaning supplies(Lint-free microfiber cloth and mild cleaning solution for the glass)
- Color test sheet (optional)(Helps calibrate color accuracy when needed)
Steps
Estimated time: 25-40 minutes
- 1
Prepare the scanner and workspace
Clear the area and connect the scanner to your computer. Power on the device and let it initialize. Ensure the glass is clean to avoid smudges that affect image quality.
Tip: Wipe the glass with a lint-free cloth before loading each page to prevent specks from showing in scans. - 2
Load the document correctly
Place the document face down on the glass, aligning it with the corner marks. Make sure pages are flat and do not overlap. Close the lid gently to prevent shifting during the scan.
Tip: For multi-page scans, use the document feeder if available and ensure pages are straight for reliable feed. - 3
Select scanning settings
Open the scanning software and choose color mode, resolution, and file format. For text-heavy documents, select black and white or grayscale at 200–300 DPI; for mixed media, use color at 300–600 DPI. Enable OCR if your goal is searchable text, and choose a PDF or TIFF output as appropriate.
Tip: Set a consistent naming convention for all scans to ease later retrieval. - 4
Preview and adjust
Run a preview to check alignment, margins, and brightness. If necessary, crop borders and adjust contrast before the final scan. Correct any skew by re-feeding the page.
Tip: Use automatic deskew if available to save time while preserving accuracy. - 5
Scan and save
Execute the scan and save to a designated folder. If doing multiple pages, ensure each page is captured in the correct order. Verify the first and last page for completeness.
Tip: Whenever possible, save to a high-quality format like PDF/A for archival purposes. - 6
Post-process and organize
Review the scanned files for clarity and consistency. Run OCR if not already performed, and apply metadata or tags to facilitate search. Move files into a logical folder structure for easy access.
Tip: Standardize file naming with date, title, and version for long-term organization.
Common Questions
What DPI should I use for document scanning?
For most documents, 200–300 DPI offers clear text with reasonable file sizes. If your documents include detailed graphics or small print, 300–600 DPI improves legibility and OCR accuracy. Adjust based on your needs and test a sample first.
For most documents, start with 200 to 300 DPI. If you have small print or detailed graphics, try 300 to 600 DPI and test a sample scan.
Can I scan multiple pages into a single PDF?
Yes. Use the scanner’s feeder or multi-page scanning feature if available. Ensure pages are aligned and in the correct order before saving. Most software lets you combine pages into one PDF or TIFF file.
Yes, you can scan multiple pages into one PDF by using the feeder and the software’s multi-page option. Keep pages aligned for proper order.
Do I need OCR software to search text?
OCR converts images of text into searchable text layers. Some scanners include built-in OCR, while others require separate software. For best results, enable OCR during or after scanning and save as a searchable PDF.
OCR lets you search text in your scans. Use OCR during scanning or with dedicated software to create searchable PDFs.
Which file formats are best for archiving scanned documents?
PDF/A is ideal for long-term archiving because it preserves content and ensures readability. For raw image preservation, TIFF can be used, but it creates larger files. JPEG is common for quick sharing but not ideal for archival quality.
Use PDF/A for long-term archives. TIFF is good for raw images but larger; avoid JPEG for archival storage when possible.
How do I clean the scanner glass safely?
Power off the scanner, unplug it, and use a microfiber cloth with a mild, non-ammonia cleaner or plain water. Wipe in a single direction to avoid streaks, and let the glass dry before scanning. Regular cleaning prevents spots and artifacts.
Power off, clean with a microfiber cloth and a mild cleaner, wipe in one direction, and dry before use.
What is duplex scanning and when should I use it?
Duplex scanning captures both sides of a page in a single pass if your hardware supports it. It saves time and keeps pages in order, but requires compatible software and sometimes higher DPI to capture backside content clearly.
Duplex scanning captures both sides in one pass where supported. It’s faster but may need tweaking for backside clarity.
