What do I do if my scans are blurry, have lines, or are completely black?

In this article, we will discuss one common way of calibrating your scanner to ensure better scanning quality. Also included are links to the required materials if you do not already have them.

The following article can be applied to a couple of different models of scanners - Ambir 490i, Ambir PS667, and Ambir PS600.

Calibrating your printer can help to solve a lot of quality issues. These issues include:

  • Blurry Scan Images
  • Lines in Scan
  • Completely Black Scans

If you notice a decline in image quality, you should re-calibrate your scanner. For an average user, we recommend calibrating your scanner about every three months. For heavy users, once a month may be necessary. Generally, the best indicator of a needed cleaning will be the appearance of any black streaks, or if your auto-crop/auto-size functions stop working on scans.

Before calibrating, please ensure the scanner is plugged in and properly connected to the computer.

To properly calibrate your scanner, please use the following instructions:

1. Double-click on the AmbirScan icon on your desktop. If you don't have that, you can download the installer here.


2. Click on "Settings".


3. Click on "Cleaning & Calibration".


4. A window similar to the one pictured below will appear. It asks you to insert "black and white calibration paper". This likely came with your scanner, but if you do not have that you can use a blank sheet of white printer paper instead. You can also purchase these supplies from CDP at the following links:

Insert it into the scanner and click "Calibrate". The scanner will then read the blank page and calibrate itself.
