Hello,
I am sorry to hear you are having problems with your M425. Can you provide samples of the black scans? That will help us better understand the problem and provide a solution. If the document is confidential you can private message me with the sample. Other questions that will provide helpful information.
- Flatbed or ADF?
- If ADF, is it side 1, side 2, both?
- Mono or color or both?
- Does copy and fax have the issue too or just scan?
