Printer Scanner "Vertical Line" on Every Page
4.5
When using the document feeder, every scan has a thin vertical line in the same spot.
Symptoms
- Vertical line
- Ruined scans
- Consistent mark
Possible Causes
- Speck of dust on the small scanner glass
Step-by-Step Fix
1
Clean the Small Glass Strip
Don't clean the big flatbed; clean the tiny 1-inch strip of glass to the left.
2
Use a Flashlight
Look for a tiny speck of white-out or ink on that glass strip.
3
Use Microfiber and Alcohol
Gently scrub the spot until it is perfectly clear.
When to See a Technician
A single speck of dust on the feeder glass becomes a line as the paper is pulled over it.
