- You can clean or calibrate your Neat scanner using the Neat Desktop Application.
- Find cleaning supplies here.
- In a pinch, you may dab isopropyl alcohol on the leading edge of a plain white sheet of paper as a temporary cleaning sheet.
- If you've misplaced the calibration sheet, you may use a blank white sheet for calibration.
- You may need to clean or calibrate your scanner many times in some cases.
- If you have the NeatConnect scanner, you can follow the steps in the link above or you can clean and calibrate the scanner from the Maintenance section of the built-in Settings Menu.
- Additionally, you can manually clean your NeatDesk or NeatConnect scanner by following the steps detailed here.
If it is defective and you have the ND-1000 or NC-1000, which scan both sides of a page simultaneously, you may be able to get by a little longer by scanning 2-sided with the remove blank pages option turned on and your pages facing backwards. This works if the front lens is faulty, but the rear lens still works.
