> Scan a double sided bank statement without shuffled pages: duplex settings, the flip-the-stack method, and spotting blank backs before OCR.
To scan a double sided bank statement in order, use the scanner's duplex setting if it reads both sides in one pass. On a single-sided feeder, scan all the fronts, flip the stack, scan the backs, then interleave the two batches. Before OCR, remove blank backs and check that page numbers and balances run in sequence.

## Duplex settings for a double sided bank statement

Duplex scanning reads both sides of each sheet in one pass, so a double sided statement comes out as front, back, front, back without any sorting. Look for a setting called Duplex, 2-sided or Both sides in the scan dialog. If the options mention only a single side, your feeder probably cannot do it.

Two kinds of duplex exist, and they behave differently:

- **Single-pass duplex** has a sensor on each side of the paper path. The sheet goes through once and both faces are captured.
- **Reversing duplex** pulls the sheet through, flips it inside the machine, and feeds it again. It is slower, and on some models it can jam on thin or creased paper.

Check two more settings while you are in the dialog. Set the binding or flip edge to the long side, which matches how most statements are printed. A short-edge setting can save every back page upside down. Then look for an option to skip blank pages, covered in a later section.

Most flatbed-only scanners have no duplex at all. On those, you scan each side by hand, turning the sheet over on the glass, and the order stays right as long as you work through the pile one sheet at a time.

## The flip-the-stack method for double sided statements

The flip-the-stack method gets both sides through a single-sided feeder in two passes. Scan the whole stack once to capture the fronts. Then turn the stack over and scan again to capture the backs. On many feeders the backs come out in reverse, so the last step is to interleave the two batches in the right order.

### A worked example with three sheets

Take an example statement of three sheets, printed on both sides, so six pages in all.

| Step | What you do | Pages captured, in file order |
| --- | --- | --- |
| 1 | Feed the stack fronts up | 1, 3, 5 |
| 2 | Turn the whole stack over and feed it again | 6, 4, 2 |
| 3 | Combine with the second batch reversed | 1, 2, 3, 4, 5, 6 |

The reversal in step 2 happens because turning the stack over puts the last sheet on top. Some scanner programs have a setting for this, often called interleave, collate or combine with reverse order, that joins the two batches for you. If yours does not, any PDF tool that reorders pages will do it.

Count the sheets before you start, and count the pages in each batch afterwards. A feeder that pulls two sheets together drops two pages from one batch, and the interleaving then pairs every later front with the wrong back.

## Why do blank statement backs matter before OCR?

Blank backs matter because every page goes through OCR and into the conversion, even when it holds nothing useful. An empty page adds a little time. A back printed only with terms and conditions adds paragraphs of text that a converter may try to read as rows. Either way the cleaner input is the file without them.

Statement backs usually fall into three kinds:

- **Truly blank.** Safe to delete. Many scanners can skip them automatically with a blank page threshold, but check the setting does not also drop a nearly empty last page that holds only a closing balance.
- **Terms, notices or a fee schedule.** These carry no transactions. Remove them from the file you convert and keep the full scan as your record.
- **Continued transactions.** Some banks print the transaction list on both sides to save paper. These are real pages and must stay.

Credit card bills often print the cardholder agreement or payment instructions on the back of each sheet, so this step matters even more there. [Converting a scanned credit card statement to Excel](/blog/scanned-credit-card-statement-to-excel) covers the other parts of that layout.

## How do you confirm double sided statement pages run in order?

Confirm the order with page numbers first and balances second. Most statements print "Page 2 of 6" or similar on each page. Flip through the file and check the sequence. Then check that each page's opening or carried-forward balance equals the closing balance of the page before it.

The balance check catches what page numbers miss. A page can be present and numbered correctly but come from another month's statement that was in the same envelope. Only the balance shows that it does not belong.

After the conversion, a few more signs point to a shuffled scan:

- dates that jump backward partway through the sheet
- a transaction count far below what the paper shows
- a running balance that breaks at one page and never recovers

When dates look out of place in a spreadsheet, check whether the cause is page order or the format itself. In Google Sheets, a day and month swap from the import locale looks similar, and [fixing dates in Google Sheets after a CSV import](/blog/fix-dates-in-google-sheets) covers that case. For how OCR builds rows from each page once the order is right, see [how OCR turns a scanned PDF into Excel](/blog/ocr-pdf-to-excel).

## Bleed-through on thin double sided statement paper

Bleed-through happens when print on the back of a thin sheet shows faintly through the front in the scan. To a person it is a pale ghost. To OCR it can be a second set of characters, mirrored, sitting between the real lines, which adds noise and sometimes stray digits to an amount column.

Three steps reduce it:

1. **Put a dark sheet behind the page** on a flatbed. Black card behind the statement absorbs light that would otherwise pass through and pick up the reverse.
2. **Lower the brightness slightly,** or use a background removal setting if the scanner has one, so faint marks drop out.
3. **Scan in greyscale** rather than colour, which keeps the real print strong while the ghost stays pale.

If the ghost is still visible after that, and amounts come back with extra digits, the scan may simply be too poor to use as it is. [When a low quality scan should be redone instead of converted](/blog/low-quality-scan-to-excel) helps you decide.

FastBankConvert is built to read scanned statement PDFs as well as digital ones and to warn you before download when the balances do not add up, which is how a missing or swapped page shows itself. It is getting ready to open, and you can [join through Get started](/get-started).
