Black, gray, or white vertical bar in scan or copy image check

Issue description

Electrostatic discharge events may occur in the Automatic Document Feeder which consequently cause sections in the Contact Image Sensor (CIS) Bar to ‘latch up’ or lock in a certain color. These ‘latch up’ events manifest as vertical bars at least 3 mm wide in a scan or copy image which may be white, black, or gray in color.

See the print defect samples below.

Solution

1. Restart your printer and retry the scan or copy job. If the issue persists, proceed to the next step.



2. Clean the scanner by following the steps outlined here. Retry the scan or copy job.
