1 Gray zone on one side of Scan
Hello,
I have an ADF scanner that failed to scan documents, from one day to the next.
On one side (the front side), a zone is completely dark gray, about 5cm wide:
The reverse side is okay:
Do you have experience with this kind of device? I haven't disassembled the scanner yet. Viewing some videos, I carefully cleaned the sensor's glass with a paper towel and isopropyl alcohol, with no luck: nothing changed. I suppose the gray zone is too wide to be caused by a dirty glass.
Thank you in advance for your help!

Hello,
I suppose the contact image sensor is dead. After 3 hours of trying to disassemble the device, here are the reference parts:
* The first side ("recto"): Brother D00S3P001
* The second side ("verso"): Brother D00S3N001
The second side is the same sensor, with an additional plastic part with 3 screws.
The sensor is a Lite-On DL520-01UHF-D. This is very hard to find and expensive. This part is shared by both the Brother ADS-2700W and the Brother ADS-2200. You can find a Brother ADS-2200 working for less than the sensor itself...
