Difficulty: MediumPrinter Technologies and Consumables Maintenance

A desktop support technician is troubleshooting a high-volume color inkjet printer that is producing output with evenly spaced horizontal blank lines across printed images and text. The ink level indicator shows that all ink cartridges are more than half full. Which of the following maintenance steps should the technician perform first to resolve this print defect?

  1. Execute a printhead nozzle cleaning cycle using the printer's utility menu.Answer
  2. B
    Replace the fuser unit assembly to ensure ink proper thermal bonding.
  3. C
    Perform a hard factory reset to clear corrupt print spooler cache memory.
  4. D
    Calibrate the optical drum unit corona wire charging voltage.

Answer

The technician should execute a printhead nozzle cleaning cycle using the printer's utility menu.
In inkjet printing, dried ink can accumulate inside the microscopic nozzles of the printhead, preventing ink droplets from reaching the page and creating horizontal white lines across printouts. Executing a printhead nozzle cleaning cycle clears dried ink buildup using pressurized ink flow.

Step-by-Step Solution

1
Analyze the reported symptom and printer technology type.
Identified horizontal blank lines on an inkjet printer with sufficient ink levels.
Horizontal streaks or missing lines on inkjet output indicate dried ink blocking one or more printhead nozzles.
2
Select the appropriate non-hardware-replacement maintenance step.
Initiate a built-in printhead cleaning routine.
Automated cleaning routines prime the printhead and push ink through the nozzles to dissolve obstructions before replacing hardware components.
