Question about Brother MFC-8860DN Printer

1 Answer

Scanning I need to figure out a way to scan large documents with a high enough dpi to be legible but not have them end up over 10MB so that I can attach them to e-mail. The only way I have found to keep the size down is to decrease the quality, which doesn't work well for the recipient. I have a Brother MFC-8860DN networked into my computer. Any suggestions???

Re: Scanning

One approach that works for me is to scan the document at high resolution and then shrink it afterwards. For some reason this seems to result in higher quality than scanning at the final (lower) resolution in many cases. For example I use ACDSee Photo Manager to scan or post process a scan from elsewhere. Within ACDSee there is an option in the jpg output (file save as) dialog for quality versus compression. I set this to default to the highest compression and resave the jpg or convert to jpg if the file did not start out that way. This generally shrinks the file by up to 2x or even 4x without any degradation that I can see. For example the screen capture below went from 39k to 18k after this step with no resolution change. If that is not enough I then perform a resize operation, for example 50% which would further reduce the file size down to a quarter of the input size (the dimensions in each direction would shrink by 50%. Even after shrinking, I find that files lookbetter than if they had simply been scanned at the final resolution.f611aa5.jpg

I have used last 4 year canon 2900B printer. How to set 300 dpi printing resoluation

Canon PIXMA Manuals MG2900 series Resolution
Resolution The data in the image you have scanned is a collection of dots carrying information about brightness and color. The density of these dots is called "resolution", and resolution will determine the amount of detail your image contains. The unit of resolution is dots per inch (dpi). Dpi is the number of dots per inch (2.5 cm). The higher the resolution (value), the more detail in your image; the lower the resolution (value), the less detail.

How to Set the Resolution You can set the resolution in Resolution on the (Scanning from a Computer) tab of the Settings dialog.
Appropriate Resolution Settings Set the resolution according to the use of the scanned image.
Item Type Use Color Mode Appropriate Resolution Color photo Copying
(Printing) Color 300 dpi Creating a postcard Color 300 dpi Saving to a computer Color 300 dpi Using on a website or attaching to e-mail Color 150 dpi Black and white photo Saving to a computer Grayscale 300 dpi Using on a website or attaching to e-mail Grayscale 150 dpi Text document (document or magazine) Copying Color, Grayscale, or Black and White 300 dpi Attaching to e-mail Color, Grayscale, or Black and White 150 dpi Scanning text using OCR Color or Grayscale 300 dpi Important
  • If you double the resolution, the data size of the scanned image quadruples. If the file is too large, the processing speed will slow down significantly, and you will experience inconvenience such as lack of memory. Set the minimum required resolution according to the use of the image.
  • When you will be printing the scanned image by enlarging it, scan by setting a higher resolution than the recommended one above.

How do I reduce file size for scanned documents?

You're probably scanning at a high DPI or resolution. Try scanning at a lower DPI or shrinking the actual dimensions of the image in an image editing program.
File format is important also. .jpg files are compressed and take up far less space than .bmp files, for instance.

Adjust the Scan setting to the defalult/appropriate resolution. See guidelines below.


300 dpi black-and-white or 200 dpi grayscale or color

Documents of poor quality or that contain small text:

400 dpi black-and-white or 300 dpi grayscale

Please help... when i scan more than 10 docs and then try to attach it to an email, it states that the file is too large ... please help me with my Lexmark X4270

You should setup the scan resolution to a lot less.
Scanned images can take a lot of space it scanned at high resolution and with many colors.
If it is a document, you can set it to scan black and white or gray and instead of the default resolution (300dpi) you should try scanning at 75dpi or 100dpi.
Those settings can reduce a scanned image to few ks instead of 10s of megs.

The average mail systems can't handle mail messages larger than 10Mb.

I would also suggest playing with the scanner to get the best results before trying to mail the scanned documents.

The document size is too big when scanning

I'm assuming that you mean the scanned image is to big to fit the screen, and not that the document you are scanning is too big to fit in the scanner...

Try reducing the resoloution of the scan, this will redce the size of the scanned image.

EG: at the moment your probably scanning at 1200 dpi, when 300 dpi might suit the application better.

Scanning files to large

It's the resolution you are using to scan. Try a lower setting. for documents, 150-200 dpi is fine. That will produce smaller files.

Scan file from Lexmark 6100 is very large

If the documents you are scanning are black and white, make sure you are selecting that in the scanner dialogue box. If you need to keep gradiants, but don't need color, try selecting grayscale. If you are adjusting your DPI (dots per inch) to the maximum (300), try using something lower (recommend 150). Lastly, check the settings in the software you use to create PDFs to ensure they are the same as what you use at the office.

Scan views fine; prints fuzzy

Try to change the dpi to the maximum, maybe 600 dpi. This will make the picture more defined.
