All documents printed by the laser printer in the branch office have ghost or shadow images appearing on the paper. What should the technician do to resolve the issue?

To resolve the issue of ghost or shadow images appearing on the paper when using a laser printer, the technician should consider the following steps:

1. Replace the Drum: Ghosting or shadowing on printed documents is often a sign of a problem with the printer’s drum unit. Over time, the drum can wear out or become damaged, leading to poor quality prints. Replacing the drum unit in the laser printer is likely to resolve this issue.

The other suggestions are less likely to address this specific problem:

• Configure the Printer for Duplex Printing: This setting adjusts how the printer handles double-sided printing and is not related to the quality of the images being printed, such as ghosting.
• Update the BIOS: Updating the BIOS (Basic Input/Output System) is related to the computer’s firmware and is unlikely to have any impact on a printer’s output quality.
• Update the OS (Operating System): While keeping the OS updated is generally good practice, it’s unlikely to directly resolve a hardware-related print quality issue like ghosting.
• Connect the Printer Using Wireless: Changing the printer’s connection method from wired to wireless (or vice versa) will not affect the print quality or resolve issues like ghosting.

Additionally, it may be helpful to perform a general maintenance check on the printer, including cleaning and ensuring all other consumable parts (like toner cartridges) are in good condition.
