# Common error messages
|
|||
|
|
|
|||
|
|
## Page already has text
|
|||
|
|
|
|||
|
|
:::{code}
|
|||
|
|
ERROR - 1: page already has text! – aborting (use --force-ocr to force OCR)
|
|||
|
|
:::
|
|||
|
|
|
|||
|
|
You ran ocrmypdf on a file that already contains printable text or a
|
|||
|
|
hidden OCR text layer (it can\'t quite tell the difference). You
|
|||
|
|
probably don\'t want to do this, because the file is already searchable.
|
|||
|
|
|
|||
|
|
As the error message suggests, your options are:
|
|||
|
|
|
|||
|
|
- `ocrmypdf --force-ocr` to
|
|||
|
|
`rasterize <raster-vector>`{.interpreted-text role="ref"} all vector
|
|||
|
|
content and run OCR on the images. This is useful if a previous OCR
|
|||
|
|
program failed, or if the document contains a text watermark.
|
|||
|
|
- `ocrmypdf --skip-text` to skip OCR and other processing on any pages
|
|||
|
|
that contain text. Text pages will be copied into the output PDF
|
|||
|
|
without modification.
|
|||
|
|
- `ocrmypdf --redo-ocr` to scan the file for any existing OCR
|
|||
|
|
(non-printing text), remove it, and do OCR again. This is one way to
|
|||
|
|
take advantage of improvements in OCR accuracy. Printable vector
|
|||
|
|
text is excluded from OCR, so this can be used on files that contain
|
|||
|
|
a mix of digital and scanned files.
|
|||
|
|
|
|||
|
|
## Input file \'filename\' is not a valid PDF
|
|||
|
|
|
|||
|
|
OCRmyPDF checks files with pikepdf, a library that in turn uses libqpdf
|
|||
|
|
to fixes errors in PDFs, before it tries to work on them. In most cases
|
|||
|
|
this happens because the PDF is corrupt and truncated (incomplete file
|
|||
|
|
copying) and not much can be done.
|
|||
|
|
|
|||
|
|
You can try rewriting the file with Ghostscript:
|
|||
|
|
|
|||
|
|
:::{code} bash
|
|||
|
|
gs -o output.pdf -dSAFER -sDEVICE=pdfwrite input.pdf
|
|||
|
|
:::
|
|||
|
|
|
|||
|
|
`pdftk` can also rewrite PDFs:
|
|||
|
|
|
|||
|
|
:::{code} bash
|
|||
|
|
pdftk input.pdf cat output output.pdf
|
|||

Sometimes Acrobat can repair PDFs with its [Preflight
|
|||
|
|
tool](https://helpx.adobe.com/acrobat/using/correcting-problem-areas-preflight-tool.html).
