Scan takes too long

●

Scanning with higher scan resolution takes longer and results in larger file sizes. Lower the

resolution to scan more quickly.

●

If you sent a print or copy job before you tried to scan, the scan starts if the scanner is not busy.

However, the printing and scanning processes share memory, which means that the scan might

be slower.

Part of the document did not scan or text is missing

●

Check the original

◦

Make sure that you loaded the original correctly.
For more information, see Load an original on the scanner glass or Load an original in the

document feeder.

◦

If you scanned the document from the document feeder, try scanning the document directly

from the scanner glass.
For more information, see Load an original on the scanner glass.

◦

Colored backgrounds can cause images in the foreground to blend into the background.

Try adjusting the settings before you scan the original, or try enhancing the image after you

scan the original.

●

Check the settings

◦

Make sure that the paper size loaded in the input tray is large enough for the original that

you are scanning.

◦

If you are using the HP printer software, the default settings in the printer software might be

set to automatically perform a specific task other than the one that you are attempting. See

the on-screen Help for the printer software for instructions about changing the properties.

Text cannot be edited

●

Make sure that the OCR (optical character recognition) program has been installed:
Depending on your operating system, do one of the following:

◦

Windows 8.1: Click the down arrow in lower left corner of the Start screen, select the printer

name, and then click Utilities. Select Printer Setup & Software. Click Add more software,

click Customize Software Selections, and make sure the OCR option is selected.

◦

Windows 8: Right-click an empty area on the Start screen, click All Apps on the app bar,

select the printer name, and then click Utilities. Select Printer Setup & Software. Click Add

more software, click Customize Software Selections, and make sure the OCR option is

selected.

◦

Windows 7, Windows Vista, and Windows XP: From the computer desktop, click Start,

select All Programs, click HP, select your printer name, and then select Printer Setup &

Software. Click Add more software, click Customize Software Selections, and make sure

the OCR option is selected.

When you scan the original, make sure that you select a document type in the software that

creates editable text. If text is classified as a graphic, it is not converted to text.
If you are using a separate OCR program, the OCR program might be linked to a word-

processing program that does not perform OCR tasks. For more information, see the

documentation provided with the OCR program.

Make sure you have selected an OCR language that corresponds to the language used for the

document you are scanning. For more information, see the documentation provided with the

OCR program.

●

Check the originals

◦

Make sure that you loaded the original correctly.
For more information, see Load an original on the scanner glass or Load an original in the

document feeder.

◦

Make sure the document is not skewed.

◦

The software might not recognize text that is tightly spaced. For example, if the text that the

software converts has missing or combined characters, "rn" might appear as "m."

◦

The accuracy of the software depends on the image quality, text size, and structure of the

original and the quality of the scan itself. Make sure that your original has good image

quality.

◦

Colored backgrounds can cause images in the foreground to blend too much.

Scanned image quality is poor

●

Text or images on the back of a two-sided original appear in the scan
Two-sided originals can "bleed" text or images from the back side to the scan if the originals are

printed on paper that is too thin or too transparent.

●

Unwanted lines
Ink, glue, correction fluid, or an unwanted substance might be on the scanner glass. Try cleaning

the scanner glass.
For more information, see Maintain the printer.

●

The scanned image is skewed (crooked)
The original might have been loaded incorrectly. Be sure to use the paper-width guides when

you load the originals into the document feeder. For more information, see Load an original in

the document feeder.
For best results, use the scanner glass for scanning rather than the document feeder. For more

information, see Load an original on the scanner glass.

●

The scanned image shows blots, lines, vertical white stripes, or other defects

◦

If the scanner glass is dirty, the image produced does not have optimum clarity.
See Maintain the printer for cleaning instructions.

◦

The defects might be on the original and are not a result of the scanning process.

●

Size is reduced
The HP printer software settings might be set to reduce the scanned image.
See the HP printer software Help for more information about changing the settings.
