220-1101 Question 467
Single answerStaple jamsA technician is troubleshooting a multifunction laser printer in an office that repeatedly reports a finishing-unit error and stops when users print stapled packets. Loose pages print normally, but jobs that require stapling stop before completion. The technician opens the finisher and sees several bent staples lodged near the stapler head. Which action should the technician take FIRST to resolve the issue safely and correctly?
- A
Power off the printer, follow the finisher's jam-clearing procedure to remove the stuck staples, and reload the correct staple cartridge if needed
- B
Use compressed air to blow the staples deeper into the stapler assembly so the sensor can reset
- C
Disable duplex printing because two-sided jobs commonly cause staple jams in the paper path
- D
Run a printhead cleaning cycle and calibrate the toner density before printing another stapled packet
Show answer and explanation
Correct answer: A
Explanation
This question focuses on practical printer troubleshooting in A+ Core 1: identifying the specific failed component and applying the correct first step. Because loose pages print normally, the main print engine and paper feed are likely functioning. The failure occurs only during stapled jobs, and bent staples are visible in the stapler head, which strongly indicates a staple jam in the finishing unit. Best practice is to power down or otherwise place the device in a safe service state, follow the vendor's documented jam-clearing steps, remove lodged staples carefully, inspect for damaged or incorrect staples, and then test with a small stapled job. Manufacturer service guides for multifunction printers and finishers typically emphasize clearing jams from the exact affected assembly and using only the correct staple cartridge and approved procedure to avoid damaging the stapler head or sensors.
- A. Correct.
This is the correct answer. A staple jam in the finisher/stapler unit should be handled by stopping operation, safely opening the assembly, and removing the jammed staples according to the manufacturer's procedure. If the staple cartridge is damaged, empty, misseated, or the wrong type, reseating or replacing it is an appropriate next step. This matches standard printer troubleshooting practice: identify the jam location, clear the obstruction, verify supplies, and test functionality.
- B. Incorrect.
This is incorrect. Compressed air is not an appropriate way to clear jammed staples from a stapler mechanism. It can push debris farther into the assembly, damage sensors, or create a safety hazard from flying metal fragments. A candidate might choose this because compressed air is often used for dust removal, but it is not the proper tool for a metal jam in a finishing unit.
- C. Incorrect.
This is incorrect. Duplex printing is not the root cause indicated by the scenario. The problem occurs specifically when the finishing unit attempts to staple, and the technician has already found bent staples lodged in the stapler head. Although duplex jobs may change page handling, the evidence points to a staple jam, not a duplexer issue.
- D. Incorrect.
This is incorrect. Printhead cleaning and toner calibration address print-quality problems such as streaking, color alignment, or density issues. They do not resolve a mechanical jam in the finisher. Someone might pick this option if they broadly associate printer maintenance with any printer error, but the symptom here is clearly related to the stapler mechanism.
