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). NOTE Scanning ppi levels are not interchangeable with printing dpi (dots per inch) levels. Color, grayscale, and black and white define the number of colors possible. You can adjust the scanner hardware resolution to up to 1200 ppi with the HP LaserJet 3052/3055/3390/3392 all-in-one or up to 600 ppi with the HP LaserJet 3050 all-in-one. The software can perform an enhanced resolution up to 19,200 ppi. You can set color and grayscale at 1 bit (black and white), or at 8 bit (256 levels of gray or color) 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). 150 Chapter 8 Scan ENWW

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).

NOTE

Scanning ppi levels are not interchangeable with printing dpi (dots per inch) levels.

Color, grayscale, and black and white define the number of colors possible. You can adjust the

scanner hardware resolution to up to 1200 ppi with the HP LaserJet 3052/3055/3390/3392 all-in-one

or up to 600 ppi with the HP LaserJet 3050 all-in-one. The software can perform an enhanced

resolution up to 19,200 ppi. You can set color and grayscale at 1 bit (black and white), or at 8 bit (256

levels of gray or color) 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).
