ユーザーから、レーザー プリンターの印刷物に線や汚れが入っているという報告がありました。また、プリンターの用紙送りが時々失敗します。この問題を解決するには、技術者は次のどのコンポーネントを交換する必要がありますか?
正解:B
Comprehensive and Detailed In-Depth Explanation:
A maintenance kit for a laser printer often includes rollers, fuser, and other parts that wear out over time.
If the printer is smudging and misfeeding, it's a sign that multiple components are failing, which a maintenance kit is designed to resolve.
* Option A (Fuser): May cause smudging if it's not heating correctly, but it won't resolve paper misfeeds alone.
* Option C (Corona wire): Can cause poor image quality if dirty but doesn't affect paper feeding.
* Option D (Toner cartridge): Can cause streaks if defective, but not paper feed issues.
CompTIA A+ Core 1 Exam Objective Reference:
* Objective 3.4: Given a scenario, install and configure printers.
