9. Hints and tips
To obtain a quality print, your image resolution should be slightly
higher than the printer's given LPI. To calculate this ideal
resolution, multiply the LPI by about 1.5 to obtain the ideal pixel
per inch (ppi) figure for your image. For example, given a 360 dpi
photo-quality printer with a 150 lpi, you can get a photo-quality
print if your image has 150 x 1.5 or 225 ppi. If you do not know
your printer's lpi, the best way to find your optimal print resolution
is to experiment. Print a test image at various resolutions to find
out what your minimum ppi is for a photo-quality print. A good test
image is a close up picture of a newspaper or a photo that has
some angled straight edges in it.
Black and white scanning mode
In Black and White mode, scan Long Edge Feed (LEF) whenever
possible. Scanning LEF allows the scanner image module to
travel quickly across the document, allowing it to finish a scan
quicker, and if scanning from the Document Feeder, to begin
scanning the next document sooner. To scan a large stack of
documents quickly using the Document Feeder, feed the stack
LEF.
NOTE: When scanning in Grayscale or Color modes, feed your
originals Short Edge Feed (SEF). This is significantly faster than
Long Edge Feed for these modes.
