							Using page-by-page scanning
NoteFor best results, load originals in the automatic document feeder (ADF) input tray, not the
flatbed scanner.
1. Load the originals that are to be scanned face-up in the ADF input tray. Adjust the media
guides to hold the originals in place.
2. If the device is connected directly to your computer, the HP Director opens after you
insert an item into the automatic document feeder ADF input tray. If the HP Director
does not automatically open, double-click the desktop alias for the HP Director.
3. To open the HP LaserJet Scan dialog box, click the HP LaserJet Scan button in the
HP Director.
4. Specify an image type.
5. Click Scan.
6. After the scan process has finished, click Scan next page.
7. Repeat step 6 for each page of the original.
8. After all of the pages have been scanned, click Send Now!.
OR
Click the Save As icon to save the pages to a file.

							Scanning by using TWAIN-compliant and WIA-compliant software
The device is TWAIN-compliant and Windows Imaging Application (WIA)-compliant. The
device works with Windows-based and Macintosh-based programs that support TWAIN-
compliant or WIA-compliant scanning devices.
Using TWAIN-compliant and WIA-compliant software
While you are in a TWAIN-enabled or WIA-enabled program, you can gain access to the
scanning feature and scan an image directly into the open program. For more information,
see the Help file or the documentation that came with your TWAIN-compliant or WIA-
compliant software program.
Scanning from a TWAIN-enabled program
NoteThe Macintosh device software complies with TWAIN Version 1.9 requirements.
Generally, a software program is TWAIN-enabled if it has a command such as Acquire, File
Acquire, Scan, Import New Object, Insert from, or Scanner. If you are unsure whether
the program is compliant or you do not know what the command is called, see the software
program Help or documentation.
When scanning from a TWAIN-enabled program, the HP LaserJet Scan software program
might start automatically. If the HP LaserJet Scan program starts, you can make changes
while you are previewing the image. If the program does not start automatically, the image
goes to the TWAIN-enabled program immediately.
To scan from a TWAIN-enabled program
Start the scan from within the TWAIN-enabled program. See the software program Help or
documentation for information about the commands and steps to use.
Scanning from a WIA-enabled program (Windows XP only)
WIA is another way to scan an image directly into a software program, such as Microsoft
Word. WIA uses Microsoft software to scan, instead of HP LaserJet Scan software.
Generally, a software program is WIA-enabled if it has a command such as Picture/From
Scanner or Camera in the Insert or File menu. If you are unsure whether the program is
WIA-enabled, see the software program Help or documentation.
To scan from a WIA-enabled program
Start the scan from within the WIA-enabled program. See the software program Help or
documentation for information about the commands and steps to use.
OR
In the Cameras and Scanner folder, double-click the device icon. This opens the standard
WIA-enabled software program, which enables you to scan to a file.

Scanning a photo 
1. Place the photo on the flatbed scanner with the picture-side down and the upper-left
corner of the photo in the lower-right corner of the glass.
2. Gently close the lid.
3. You are now ready to scan the photo by using one of the scanning methods. See
Understanding scanning methods for more information.

							Scanning by using optical character recognition (OCR) software
You can use third-party OCR software to import scanned text into your preferred word-
processing program for editing.
Readiris
The device software CD-ROMs include the Readiris OCR program. If you want to use the
Readiris program, install it from the appropriate software CD-ROM, and then follow the
instructions in the online Help.

							Scanner resolution and color
If you are printing a scanned image, and the quality is not what you expected, you might
have selected a resolution or color setting in the scanner software that does not match your
needs. Resolution and color affect the following features of scanned images:
●Image clarity
●Texture of gradations (smooth or rough)
●Scan time
●File size
Scanning resolution is measured in pixels per inch (ppi). Color, grayscale, and black and
white define the number of colors possible. You can adjust the scanner hardware resolution
to up to 1200 ppi. The software can perform an enhanced resolution up to 9,600 ppi. You
can set color and grayscale at 1 bit (black and white), or at 8 bit (256 levels of gray) to 24 bit
(true color).
The resolution and color guidelines table lists simple tips that you can follow to meet your
scanning needs.
Note
Setting the resolution and color to a high value can create large files that take up disk space
and slow the scanning process. Before setting the resolution and color, determine how you
are going to use the scanned image.
Note
The best resolution for color and grayscale images is achieved by scanning from the flatbed
scanner rather than from the automatic document feeder (ADF).
Resolution and color guidelines
The following table describes the recommended resolution and color settings for different
types of scan jobs.
Intended useRecommended resolutionRecommended color settings
Fax150 ppi●Black and White
E-mail150 ppi●Black and White, if the

							Inserting a memory card
The HP Color LaserJet 2840 all-in-one can read the following memory-card types:
●CompactFlash
●Memory Stick and Memory Stick PRO
●MultiMedia
●Secure Digital (SD)
●SmartMedia
●xD
Note
The HP Color LaserJet 2840 all-in-one memory card reader recognizes only files in .JPEG
file and sRGB color format when printing from the device control panel. To print other file
types, you must use the software, such as HP Image Zone, provided on the CD-ROMs that
came with the device. See the software online Help for information about how to print photos
from your computer. Windows operating system users also can use Windows Explorer to
move other file types to their computer and then print the files from the computer.
Insert the memory card into the appropriate slot on the HP Color LaserJet 2840 all-in-one.
To determine in which slot your memory card needs to be inserted, see the illustration below.
1 Accepts xD and SmartMedia memory cards.
2 Accepts MultiMedia, Memory Stick, and Memory Stick PRO memory cards.
3 Accepts CompactFlash memory cards.
4 Accepts Secure Digital memory cards.
The device reads the card, and then the device control panel displays X Photos found on
card, where X is the number of recognized .JPEG files found on the memory card.
Now you can use the HP Color LaserJet 2840 all-in-one to print photos.
Note
You can use only one memory card in the device at a time. If two or more are inserted, the
device displays an error message. For more information about memory-card messages, see
Memory card problems.
Note
The HP Color LaserJet 2840 all-in-one will recognize memory cards up to 2 GB.
