You have spent weeks tracking down the right documents. You have gathered your birth certificate, marriage license, academic transcripts, or immigration paperwork. You are ready to move forward. Then your translation comes back with a note: portions of the original were illegible. A stamp was cut off. A page corner was folded. The turnaround you were counting on just got delayed.
This is one of the most preventable problems in the certified translation process, and it happens more often than you might think. The quality of your scan determines the quality of your translation. A professional translator can only work with what they can see. Blurry text, shadowed corners, poor contrast, or incomplete page captures all create gaps that slow down your order or require a costly rescan.
The good news: preparing your documents correctly takes only a few extra minutes, and the payoff is enormous. This guide walks you through everything you need to know before you hit the upload button. Think of it as your pre-flight checklist for a smooth, fast, professional translation experience with ASAP Translate.
Certified translation is not just a language exercise. It is a faithful, word-for-word reproduction of everything on your document: text, headings, seals, stamps, handwritten notes, dates, and signatures. Under federal regulation 8 CFR § 103.2(b)(3), USCIS requires that a certified translation accurately reflect the original document in its entirety, including all notations. If a stamp is partially visible in your scan, the translator must note it — and the reviewing officer may flag it.
The same principle applies whether you are submitting documents to a university, a foreign consulate, an employer, or a court. Decision-makers need to trust that the translation reflects every element of the source document. When your scan is clean, complete, and high-resolution, the translator can do their job with confidence. When it is not, everyone loses time.
Before diving into the checklist, it helps to understand what translators look for when they open your file. They need to read every character of text, identify every seal and stamp (including partially faded ones), confirm page numbers and ordering, and verify that no section has been accidentally cut off. Our official translation checklist covers the full picture of what a properly prepared document looks like from start to finish.
The first decision you make — what device to scan with — sets the ceiling for everything else. You have three main options: a flatbed scanner, a multifunction printer with scan capability, or a smartphone scanning app. Each has strengths and trade-offs.
A flatbed scanner gives you the most control over resolution, color depth, and page alignment. For legal, immigration, and academic documents, this is the recommended hardware when you have access to one. Most office supply stores, libraries, and print shops have flatbed scanners available for public use if you do not own one.
Key settings to configure on your flatbed scanner before you begin:
Modern smartphone scanning apps have improved dramatically. Apps like Adobe Scan, Microsoft Lens, and CamScanner use perspective correction, automatic edge detection, and multi-frame image processing to produce surprisingly clean results. According to TechRadar's roundup of the best document scanning apps, top-tier apps can deliver output quality that rivals entry-level flatbed scanners when used correctly.
If you are using a smartphone app, follow these guidelines:
Smartphone scanning is perfectly acceptable for ASAP Translate submissions, provided the resulting image meets our quality standards. Many clients successfully use their phones for all document types.
Resolution is the single most important technical setting in document scanning. DPI stands for dots per inch — the number of individual pixels captured for every inch of the original document. Higher DPI means more detail, better legibility, and a larger file size.
According to research from eRecords USA on document scanning resolution and OCR accuracy, one of the most common scanning mistakes is using too low a resolution, which creates problems specifically for professional review workflows. Here is a practical resolution guide by document type:
A note on file size: a full-color 600 DPI scan of a standard letter-size page will typically produce a file between 10 and 30 MB. ASAP Translate's secure upload portal handles large files without issue. Do not compress your scan just to reduce file size — the quality loss is not worth it.
Before you place your document on the scanner or prepare to photograph it, take a moment to physically prepare it. This step is easy to skip, but it directly affects scan quality.
Staples, paper clips, binder clips, and rubber bands must come off before scanning. These create shadows, physical obstructions, and alignment problems that no amount of post-processing can fully correct. For multi-page documents that need to stay together, note the original page order before removing fasteners so you can reassemble correctly.
Folded documents — such as those stored in envelopes for extended periods — scan poorly along the fold lines. The crease creates a shadow valley that obscures text. Before scanning, place the document face-down on a flat surface and gently smooth it out. For stubborn folds, place the document under a heavy book for an hour before scanning.
Do not use heat or moisture to flatten documents. Heat can cause ink to smear or paper to warp, and moisture can damage the document permanently.
Dust, fingerprints, and smudges on the scanner bed transfer directly to your scanned image as dark spots or streaks. Before scanning important documents, wipe the scanner glass with a clean, dry microfiber cloth. If you are using a shared scanner at a library or office, this step is especially important.
Documents with torn edges, water staining, or brittle paper require extra care. Do not force a damaged document flat — you risk further tearing. Instead, scan as much of the legible surface as possible and note any areas of damage in your submission notes to our team. Our guide to handling documents with water damage, fading, or missing sections provides specific strategies for these challenging cases.
Once your document is on the scanner bed or positioned under your phone camera, run through this checklist before capturing:
All four margins must be visible in the scan. This is one of the most common sources of rejection. If the edge of the document is cropped, text, stamps, or signatures near the border may be missing. Verify that you can see a small border of white space on all four sides of the document.
For passports, ID cards, and smaller documents: scan the entire item without zooming in. The translator needs to see the complete document layout, not just a portion of it.
Official stamps, embossed seals, and signatures are legally significant elements of your document. Translators are required to describe or reproduce them in the certified translation. Ensure these elements are fully visible and not cut off, obscured by shadow, or washed out by glare.
Embossed (raised) seals are particularly challenging because they contain no ink — their visibility depends entirely on lighting and contrast. Scan in color mode and, if using a flatbed scanner, apply gentle, even pressure with the lid to flatten the embossment slightly for a clearer capture. If the embossment remains difficult to read, consider taking a separate close-up photo with side-lighting to supplement your scan.
For a detailed approach to difficult seals and stamps, our practical guide to translating documents with faded stamps and illegible seals covers every scenario in depth.
Each page should be scanned right-side up and level. A page that is scanned sideways or at an angle is annoying at best and a compliance issue at worst when submitted to government agencies. Most scanner software and apps offer automatic rotation — verify that the automatic rotation has not introduced a problem before saving.
For documents with multiple pages, verify the following before saving your file:
Our guide on how to translate a PDF covers file assembly and formatting best practices for multi-page submissions in detail.
Readable, descriptive filenames may seem like a minor detail, but they help our team route your documents accurately, especially when you are submitting multiple files at once. Use this naming convention:
Avoid generic filenames like scan0001.jpg or document.pdf. These create confusion when multiple files need to be matched to orders.
ASAP Translate accepts the following file formats:
Once your files are scanned, named, and organized, you are ready to upload. ASAP Translate's secure web portal encrypts your files in transit and at rest. You can also submit documents via email if you prefer. Either way, your documents are handled with strict confidentiality — we never share, store unnecessarily, or distribute your personal documents.
For a detailed walkthrough of what happens after you submit, our article on what actually happens from upload to delivery takes you through every step of our process — from receipt to final certified translation.
After uploading, you will receive an order confirmation. Our team reviews every document before beginning translation. If a quality issue is detected — a page that is too blurry, a cut-off margin, a missing page — we will contact you immediately so you can rescan rather than waiting until after translation is complete.
We understand that the documents you submit for translation are deeply personal. Birth certificates, medical records, legal proceedings, and immigration paperwork represent significant moments in your life. Data privacy in translation is something we take seriously at every level of our operations. Our confidentiality protocols meet or exceed industry standards, and all team members handling your documents are bound by strict non-disclosure agreements. Your files are never shared with third parties, and we handle every submission with the same care we would want applied to our own personal records.
Not every document arrives in pristine condition. Here is how to approach the most common challenging scenarios:
Documents that have faded due to age, poor storage, or light exposure present a real challenge. For these, always scan in color at 600 DPI. The additional tonal information captured at higher resolution often makes faded text legible in ways that a 300 DPI grayscale scan cannot replicate.
After scanning, open the file and zoom in to 100% to verify that faded text is actually readable — not just visible as a smudge. If text is too faint to read on screen, it will be too faint for a translator. In that case, try adjusting your scanner's brightness and contrast settings, or photograph the document with a strong side-light to increase contrast before scanning.
Passports, official booklets, and bound records present a common challenge: the pages near the spine curve away from the scanner bed, creating blur and shadow in the center of the spread. Scan each page individually rather than scanning both pages of an open spread. Apply gentle, even pressure with the scanner lid or your hand to keep the page as flat as possible.
For passports specifically: scan the photo and biographical data page, the visa pages, and any entry or exit stamps that are relevant to your submission. If uncertain about which pages to include, scan the entire document — it is always better to include too much than too little.
If your document has physical damage, scan what is available and submit it with a note explaining the condition. Our translators are experienced with damaged documents and will translate every legible element while noting areas that could not be read due to damage. Handling damaged documents requires specific strategies that our team is well-equipped to address.
For immigration purposes specifically, if a document is genuinely illegible due to damage, you may need to obtain a certified replacement copy from the issuing authority. Our team can advise you on next steps if this situation arises.
If your translation is destined for USCIS or another immigration authority, the stakes for document quality are especially high. According to CitizenPath's guide to USCIS certified translation requirements, the translation must accurately reflect the original document — including all text, stamps, seals, and signatures. A scan that omits or obscures any of these elements creates a compliance gap that can delay or jeopardize your application.
ASAP Translate offers a 100% USCIS Acceptance Guarantee on all certified translations. This means if your translation is not accepted by USCIS for any reason related to our work, we will re-translate at no charge. But this guarantee works best when you provide the cleanest possible source document — which is exactly what this checklist helps you do.
Key USCIS-focused scanning tips:
Use this quick-reference list every time you prepare documents for certified translation:
Here is something most people do not consider: the quality of your scan directly affects how quickly your order can be completed. When a document scan is clear and complete, our translators can work continuously from start to finish. When a scan requires clarification, our quality team must pause work, contact you, wait for a new scan, and restart. This can add anywhere from a few hours to a full business day to your turnaround.
This matters most if you have selected one of our expedited service levels:
If you are ordering rush or express service, understanding how 6-hour rush delivery actually works is essential reading. And the single most reliable way to protect your deadline is to submit a clean, complete scan the first time.
The best practices in this checklist align with established professional document management standards. According to Recordsforce's professional document scanning preparation guide, proper pre-scan preparation — including removing fasteners, flattening documents, and verifying completeness — is the foundation of any effective document digitization process. These are not arbitrary preferences; they are industry-standard practices developed across decades of document management work.
The core principle is simple: a translator, like any professional reviewer, can only work with what they can see. Your originals contain the legal truth of your life events, credentials, and records. A well-prepared scan preserves that truth faithfully. A poor scan introduces ambiguity that no amount of professional skill can fully resolve.
Now that you have your pre-translation scanning checklist, the path forward is clear. Gather your documents, apply the preparation steps above, scan at the right resolution, verify legibility, and upload through ASAP Translate's secure portal.
