If your scanner is more that three years old, or seen a lot of slides and negatives, it needs cleaning.
CoolScan scanners are know for collecting dust on their internal mirror.
As our photo shows, these mirrors get loaded with dirt, dust and debris (notice hair). When you scan, the image that is scanned is refleced to the scanning lens by this mirror.
If this mirror is loaded is dirt, your scans suffer.
This service will clean the mirror and optical system.
We'll also do a good general cleaning "under the hood", inside.
