Question 300
On a service ticket for Horizon College, the team observes: An inkjet photo printer produces blank horizontal stripes in cyan images. The supporting record states that a nozzle check identifies missing cyan nozzles while the paper path is clear. The desired outcome is to correct an ink delivery issue rather than changing duplex settings. User data and business service continuity must be preserved. Which verification result supports the intended technical outcome?
- Verify dark print appears on the active coated side without consumable ink
- Verify cyan lines are continuous and color image banding is reduced
- Verify queued and new jobs print and the queue reports the device online
- Verify repeated marks are gone across consecutive pages
Explanation
Correct Answer
B:
Verify cyan lines are continuous and color image banding is reduced. It proves the required function with an observable result instead of assuming the change worked. The relevant observation is that a nozzle check identifies missing cyan nozzles while the paper path is clear. The support goal is to correct an ink delivery issue rather than changing duplex settings; this validate action specifically addresses inkjet horizontal banding and nozzle obstruction without confusing a different subsystem.
Incorrect Answers
