How to Fix Common Scanning Issues with iScanner’s Advanced AI Tools

In the dynamic world of document scanning, quality issues are fairly common and even expected. If you’ve ever dealt with scanning your own materials or worked with images others sent, you’ve likely encountered some frustrating problems. Among the most common ones are warped lines, missing text, blurred images, and unwanted shadows.

At iScanner, we understand these challenges. Moreover, we’ve deliberately researched how people scan on the go and, as a result, have identified the most frequent scanning problems. This user-centric approach allowed us to create finely tuned AI tools. Housed in the AI Refine menu, they’re designed to tackle scanning issues head-on. What sets iScanner apart from the competition is our very own neuro-algorithms behind those AI features, offering an unmatched level of precision.

In our recent Mastery of PDFs free online course for students, we’ve created a top chart of these issues.

Let’s explore the top five most irritating scanning issues and how iScanner’s AI tools can fix them.

Wavy Lines

Wavy lines may look artistic on certain occasions, but there’s no place for them on your scanned documents. This issue typically emerges when you scan thick books or magazines, resulting in perspective distortions. It’s particularly troublesome for scanning music sheets, as wavy lines make reading notes nearly impossible.

Solution: iScanner’s AI Straightener is the perfect tool to solve this problem. Found in the AI Refine menu, it allows you to correct distorted lines with just a few taps. Once you open the document in the app, tap “Adjust,” select “AI Refine,” and hit “Straighten.” This powerful tool restores the original layout of your document by using neuro-algorithms that map out and realign skewed text and images. AI Straightener is the result of an immense amount of work. A combination of a neural network and analytical models, our new algorithm has proven to be effective at scanning documents with various layouts.

Eaten Lines

If you’re still receiving paper mail, you’ve likely encountered this problem. Official letters are often folded to fit in envelopes, and scanning them can result in entire lines of text disappearing into the creases. It’s as if those lines were “eaten” by the fold, rendering your document incomplete.

Solution: iScanner’s AI Straightener isn’t just for wavy lines — it’s also your go-to tool for restoring folded, eaten-up text. With just a few taps in the “AI Refine” menu, you can straighten your folded document and bring back those missing lines. This tool is designed to handle complex distortions with ease, making your scanned documents complete again.

Cut Fingers

Sometimes, when in a rush to scan a document, you use your fingers to hold it in place. Unfortunately, they often end up a part of the scan, leading to unsightly images of cut-off fingers on the final PDF. While quite fitting for Halloween, it’s far less entertaining when submitting important paperwork.

Solution: iScanner’s Finger Eraser solves this problem effortlessly. Located in the AI Refine menu, this tool is specifically designed to detect and remove fingers from scanned images. If multiple pages are affected, you can choose “Apply to All.” With the neuro-algorithms powering this feature, the app seamlessly erases any accidental fingers without compromising the quality of your document. The algorithm analyzes the background around the fingers and, after removing them, fills in the void with the same background color. All you need on your side is to make sure that no important data is covered by your fingers while scanning.

Blurred Text

Have you ever been in a hurry to scan documents before the deadline arrives or rushing to complete the task in one go after having too much caffeine? Blurred text is often the result of shaky hands, making scanned documents nearly unreadable.

Solution: iScanner’s Deblur tool is designed to rescue these scans. Available in the AI Refine menu, Deblur uses advanced algorithms to sharpen and bring to clarity any out-of-focus text. It handles different kinds of focus and motion blur, making it perfect for addressing blurriness caused by unsteady hands or scanning while in motion, such as on a bumpy bus ride. The algorithm sharpens blurry documents by smoothing out rough, fuzzy edges and enhancing the contrast between the text and background. In mere seconds, your document will go from a blurry mess to a crisp, readable file.

Scanned Artifacts

One of the most frustrating issues with scanned documents is the presence of unwanted artifacts — yellowed backgrounds, shadows, dust, and even blemishes. These artifacts usually occur because of poor lighting conditions, dust particles, or scratches on the document. Old or low-resolution printouts are particularly prone to these issues.

Solution: Let us introduce iScanner’s newest AI tool — AI Polish. This feature, conveniently placed in the AI Refine menu, uses cutting-edge neuro-algorithms to clean up your documents by automatically detecting and removing unwanted backgrounds, shadows, and other blemishes. AI Polish evaluates exposure and contrast, detecting over- or underexposed areas and adjusting them for balanced lighting. This helps remove artifacts such as halos. Additionally, it fine-tunes the color balance, eliminating unwanted tints to ensure whites remain true and colors appear natural. This process is essential for preserving the accuracy of the image’s color palette. Just tap “Polish,” and the app will work its magic, leaving you with a pristine, professional-looking scan.

Why iScanner’s AI Tools Stand Out

All these AI-powered features — AI Straightener, Deblur, Finger Eraser, and AI Polish — are part of the AI Refine menu in the iScanner app. These tools have been meticulously developed based on user feedback and real-world scanning scenarios, making them uniquely equipped to handle the most common problems of scanning on the go.

What truly sets iScanner apart is our proprietary neuro-algorithms, which allow for an incredibly precise and efficient refinement process. Unlike other scanning apps, iScanner doesn’t just enhance images; it intelligently analyzes them and makes adjustments that align with the real-world needs of its users. Whether you’re scanning documents for work, school, or personal use, iScanner ensures your scans achieve the highest quality with minimal effort.

Conclusion

With iScanner’s advanced AI tools, you no longer have to worry about wavy lines, missing text, blurred images, or unwanted artifacts ruining your scanned documents. The AI Refine menu, powered by our in-house neuro-algorithms, is your all-in-one solution for fixing the most common and frustrating scan issues. Whether you’re a student, professional, or simply someone who scans a lot, iScanner will help you get every document clean, clear, and ready to use.
