In the digital age, document scanning has become an essential tool for personal and professional efficiency. Scanners are used to digitize everything from invoices and contracts to receipts and personal records. However, many people still make several common document scanning mistakes that can lead to poor image quality, wasted time, and frustration. Understanding these mistakes and how to avoid them can help you optimize your scanning process for the best results.

Here are three common document scanning mistakes and tips on how to avoid them.

1. Not Adjusting Scanner Settings for Document Type

One of the most common document scanning mistakes is failing to adjust the scanner settings for different document types. Whether you're scanning a contract, a photo, or a handwritten note, each document requires specific settings to ensure the best scan quality.

How to Avoid It

Before scanning, take a moment to adjust the scanner settings according to the type of document you are scanning. For text-heavy documents, set the resolution to 300 dpi (dots per inch), which is sufficient for clarity. For images or photos, a higher resolution of 600 dpi or more is recommended for optimal detail. Additionally, choose the right color mode—black and white for text-based documents and color for photos or scanned graphics.

2. Ignoring Document Alignment

Another mistake people commonly make is placing documents haphazardly on the scanner bed. A misaligned document leads to skewed scans, wasted time, and the need for manual corrections later on.

How to Avoid It

Always ensure that your document is properly aligned with the edges of the scanner bed. Many scanners have guides or markings to help with alignment, but if yours doesn't, manually adjust the document so it sits squarely within the scanning area. This will ensure that the scan is straight, and the final document will require minimal editing.

3. Using the Wrong File Format

Using the wrong file format when scanning documents can result in large files that are difficult to store and share. Common file formats like PDF, JPEG, and TIFF each have their advantages, but if you choose the wrong one, you may experience issues with file size, accessibility, or image quality.

How to Avoid It

For text-based documents, PDF is usually the best choice because it is highly compressed without compromising the quality of the text. This makes it easier to store and share. If you're scanning photos or images, however, JPEG or TIFF might be better choices due to their ability to preserve high-quality images. Always consider the purpose of the scan when selecting the file format.
