Sometimes a scan just isn't coming out the way you planned: too bright, too dark, grainy, yellowish, etc. When that happens, you have options!
Change the Quality (DPI):
- 200 dpi: usually adequate for simply retaining a print copy of a document (not for pictures, colorful documents, or great OCR results)
- 300 dpi: is sufficient enough to be of good legibility and to provide adequate OCR results
- 400 and 600 dpi: recommended for scans with photos/images or intricate or delicate documents (will result in slower scan speeds)
Change the Compression:
- Select the GEAR icon in the top right corner of the screen.
- Click SETTINGS from the slide-out side menu.
- Choose the File Compression drop down and select your preferred compression.
- Press SAVE to finalize your changes.
This will change how much the document is compressed during a scan when it's sent to it's final destination (email, fax, Cloud, etc.) Higher compression means file sizes, but can also adjust the quality of the document just a bit. Lower compression means larger file sizes, but you won't lose all those little details in translation.
Change the Color:
-
Black and white (monochrome), only has two "colors", black (ink or toner) and white (no ink or toner). Black and white scan mode is typically used for documents that contain text, where everything that is a printed character displays as black on the scan and the background white (unprinted). Black and white mode forces everything darker than a certain threshold to black and everything else as white. This makes most standard documents easier to read and a better representation of the original.
-
Grayscale contains shades of grey (a continuous scale from black to white) and is used for reproducing images or documents that contain more than just black printed text. With Grayscale mode, the scan will reflect more of a "photograph" of the document, showing anything that has some color (including imperfections such as wrinkles, creases and sometimes the paper coloration).
- Color will scan in full color to match as shown on the page.
If that doesn't make a difference, we need to test/recalibrate the lens (for 1st Gen Original scanners with serial numbers beginning in 553 or 554):
- Select the GEAR icon in the top right corner of the screen to go to SETTINGS
- Adjust BRIGHTNESS and CONTRAST to both be 50
- Turn off REMOVE BLANK PAGES option
- Return to the HOME screen
- Go to SIDES and select TWO-SIDED (FACE DOWN)
- Do a test scan
- Go to SETTINGS and reset BRIGHTNESS and CONTRAST
- Turn back on REMOVE BLANK PAGES (if you prefer)
- Select which type of scan you prefer from SIDES
