Hi AfxTwn! Thanks for posting in the Canon Community Forum. I see that you are not satisfied with the colors produced when you use your PIXMA MG7550 to scan.
Please note that we do not support the MG7550 in the United States. We do support the MG7520 which is similar. The information in this post is for the MG7520.
If you would like to reach support in the country you are in, please visit:

You mention that the colors on your scans are much redder than you would like them to be. The colors that you see on a paper are affected by the lights that you have overhead, so they will look different under different types of light. It’s possible that the light inside the scanner is much different than the one you are using at home. The tint of the paper and the glass on the surface of the scanner can also affect the colors of your scan.
As far as printing, please note that the color profiles included with the printer driver are for paper that is white. If you are printing the image that you scanned on paper that is not white, the colors will be much different than what you see on the screen. It may be better to draw your image on paper that is white and scan it. Then, see how it looks when you print it on your paper.
You can use ScanGear to adjust the color and image settings. This program has more control over the scanner driver so you can adjust the image prior to scanning. On a Mac computer, the ScanGear option is called Driver.
To open this program, you must first open the IJ Scan Utility on your computer. When it opens, please click on the ScanGear button (on Windows computers) or the Driver button (on Mac computers). Within a minute, the ScanGear program will appear on your screen.
When the ScanGear window opens, I recommend selecting the Advanced Mode option in the top right. Then, you can click on the PREVIEW button. When you click on Preview, you will see a temporary scanned image on the left side of the window.
You can use the options on the right side of the window to adjust the image. As you are making the adjustments, you should see the change in the preview on the left side of the window. When the preview looks good to you, you can click on the Scan button and the image will be scanned again using the adjustments you made. The finished scan should look like the preview you saw on the left side of the screen.
For more information on the ScanGear program, please visit the following sections of the manual (for Windows computers):
https://ij.manual.canon/ij/webmanual/ScanGear/W/MFP/20.0/EN/SG/Top.html
https://ij.manual.canon/ij/webmanual/ScanGear/W/MFP/20.0/EN/SG/sg-904.html
The second link has information on using the Advanced Mode option in Scan Gear. In step 6, you will see links that will show you your Image Setting and Color Adjustment Button options. You can click on those links to see which options may help.
As far as the Image Settings are concerned, you can consider changing the Image Correction option to Magazine or leave it at None. You can also try setting the Grain Correction option to Low. If the image still doesn’t look right, you can try one of the other options. For example, you can turn on the Photo option (instead of Magazine).
If Image Settings do not help, you can then try the Brightness/Contrast and Saturation/Color Balance buttons. For more details about those options, you can click on the Color Adjustments link in step 6. You can use those buttons to adjust the color and brightness of the scanned images.
If you have a Mac computer, please use the links below instead:

Using the Scanner Driver option on a Mac computer is different. You can click on the Overview (instead of Preview) button to see a preview of the image. When you are done making changes, you can click on the Scan button.
On a Mac computer, you only have access to the Image Settings (not the Color Adjustments). If you have a Mac computer and you are not able to get the colors you want with the scanner driver, you will need to use another program to adjust the colors or brightness before you print.
I hope this information helps. Thanks again.
