A help desk technician receives a ticket regarding an impact dot-matrix printer used in a warehouse to print multi-part carbonless forms. The user reports that while text on the top copy is sharp, the impression on the underlying duplicate sheets is extremely faint and unreadable. Which of the following actions should the technician take to resolve this print quality issue?
- Adjust the printhead gap lever to decrease the distance to the platen.Answer
- BReplace the internal fuser assembly to increase toner heating temperature.
- CRestart the operating system print spooler service immediately without physical inspection.
- DVerify Ethernet connection speeds by observing the network interface card link lights.
Answer
Adjusting the printhead gap lever closer to the platen ensures sufficient pin strike impact force across multi-part forms.
Impact dot-matrix printers use a platen gap lever to adjust the distance between the printhead and the paper based on paper thickness. When printing multi-part continuous forms, reducing the platen gap allows the printhead pins to strike with enough mechanical force to clearly mark the pressure-sensitive carbonless layers underneath.
