A user reports that printed receipts have black smudges over the entire image. The text is still present but is very dark and sometimes illegible. Which of the following are the MOST likely cause and solution for the printer issue?
A. The ribbon is jammed and is rubbing on the paper. Clear the bad ribbon and feed it through properly.
B. The printhead is too hot. Adjust the temperature down and retry printing.
C. The printer is loaded with the wrong type of paper. Replace the receipt paper with carbon paper.
D. The blue ink cartridge was loaded with black ink. Put in the correct ink and clean the printhead.
Explanation: The black smudges over the entire image on a printed receipt are most likely caused by a jammed ribbon that is rubbing on the paper. The solution is to clear the bad ribbon and feed it through the printer properly. Ribbon jams can be caused by various issues, such as incorrect installation or a damaged ribbon.

When a user's workstation is turned on, a message displays indicating that the date and time are incorrect. Other computers on the network do not display this message. Which of the following is the most likely cause of this issue?
A. The time server is misconfigured.
B. The BIOS is not updated.
C. The CMOS battery is discharged.
D. The CPU is slow.
Explanation: A discharged CMOS battery often causes a system to lose track of time and date settings when powered off, as this battery powers the real-time clock. The BIOS settings, including time and date, revert when this battery fails. Option A (time server misconfiguration) would impact multiple devices. BIOS updates (Option B) and CPU performance (Option D) are unrelated to timekeeping issues, as outlined in CompTIA A+ Core 1 (220-1101) exam objectives under hardware troubleshooting.
A user failed to gain access to a building's entrance after security measures at the entrance were upgraded last week. The company implemented the 13.56MHz frequency short band, and users can now utilize their mobile devices to authenticate. Which of the following has to be enabled for the mobile device to authenticate?
A. Bluetooth
B. Biometrics
C. NFC
D. PIN
Explanation: NFC (Near Field Communication) is a technology used for short-range wireless communication between devices, typically used for contactless payments and authentication. In this scenario, the 13.56MHz frequency short band was implemented, and users can authenticate using their mobile devices, which requires NFC to be enabled on the device.

A user complains that print jobs remain in the printer queue. A technician sends a ping command to the printer, and the printer replies successfully. The paper trays are full, and toner levels are okay. Which of the following is a reason the print jobs are getting stuck in the queue?
A. Theprinter is disconnected from the network.
B. Thefirst job in thequeue is waiting for paper inthemanual feed tray.
C. Thepaper size forthe last job in the queue is not available.
D. Theprint queue isunable to locate the printer.
Explanation: When print jobs remain stuck in the printer queue despite successful network communication (indicated by successful ping replies) and no issues with paper supply or toner levels, a common reason can be that the first job in the queue requires manual intervention, such as paper to be fed into a manual feed tray. Printers often pause the entire print queue if the first job requires a specific type of paper or manual insertion that hasn't been addressed, preventing subsequent jobs from processing.
