220-901 A+ Certification (Exam 220-901) - HLT Week 3

You've received a call from a busy accounting department with a complaint about a printing problem. When you arrive, you find that pages are output from the printer but all of them are completely blank. Nothing appears to be written on any of the printed pages. Which of these would be the most likely cause of this issue?

f the printer's mechanical operation is working normally, then the problem must be with the internal printing process of the laser printer. A completely blank page could certainly be related to a problem with a corona wire, but the more common issue is because the laser printer cartridge is faulty or completely empty of toner.

Wireless locators

find wireless network signals.

Inkjet printers do not have a

fuser.

USB 3.1

only supports speeds up to 10 Gbs.

Print spooler

part of the Windows operating system and is responsible for receiving print jobs from applications and forwarding them to the printer. The print spooler is an important middle-man in the printing process. Without the spooler, each application would need its own system to communicate directly to the printer.

Laser Printer Components

photoreceptor drum assembly fuser discharge lamp cleaning blade corona wire toner hopper laser scanning unit developer roller

GRiDPad

was the first commercial tablet released in 1989. None of the others were released until at least the year 2000.

The iPhone 5

was the first iPhone to use the lightning connector. IPhone 6 uses it as well.

Network address translation (NAT)

is installed on a router and translates the private IP address into a public one for the user to access the Internet.

QoS level 4

is known as controlled load, which is lower priority than interactive voice and video.

GLONASS

is the Russian version of GPS. Galileo is European, BDS is Chinese, and IRNSS is Indian.

Tethering

is when a Wi-Fi enabled device attaches to a cellular device to get on the Internet. The cellular devices is usually called a mobile hotspot.

What are the advantages of a universal serial bus printer interface

it has a higher transfer rate than a serial connection it has a higher transfer rate than a parallel connection it automatically recognizes new devices

If a laptop's AC adapter is underpowered

it will halt with a warning message at boot time. If the wall socket were faulty, the laptop would use battery power.

QoS level 6

only has 10 ms latency but is reserved for control traffic.

The fuser assembly

presses and melts the toner into the paper.

If print jobs are seemingly getting stuck in the printer queue, you should stop and restart the

print spooler service.

Basic rate interface ISDN (BRI ISDN)

provides 2 separate 64Kbs B channels for data transmissions. These channels can be combined to increase throughput.

Thunderbolt 2

provides for speeds up to 20 Gbs

It's the _____ to perform triangulation to determine its position based on data received from the satellites.

receiver's job

DNS

resolves host names to IP addresses.

If an ink cartridges faulty or develops a hole, it can release excessive amounts of ink, which will lead to

smearing.

And electrophotographic (EP) laser printer toner cartridge includes the

toner, print drum, and cleaning blade. The laser is usually contained within the printer, not within the toner cartridge.

Excessive humidity may cause smearing, but it wouldn't cause the disbursement of

too much ink

The transfer Corona

transfers the toner from the drum to the paper.

What is not an advantage of a universal serial bus printer interface

unlike the network printer interface, it does not allow the printer to communicate with networks, servers, and workstations

PRI ISDN

uses 23 B channels. DSL, cable, and satellite do not offer multiple dedicated digital channels.

Google glass

uses augmented reality (AR), which is common on heads-up types of displays.

Cable testers

The power plan has been adjusted to "Do nothing" when the lid is closed b. A faulty USB device is preventing the computer from entering a power-saving mode c. The LCD cutoff switch is broken d. This is the default behavior for Windows 7

a. The power plan has been adjusted to "Do nothing" when the lid is closed A faulty cut-off switch or incompatible USB device could cause this problem but you should consider the simplest explanation first.

Battery calibration for lithium ion batteries

Spooling occurs when

an application converts and stores a print job on the PC hard drive before sending to the print queue. A print spool is a file created in the format required by the printer that can be sent to the printer in stages (as it completes each page) to avoid overfilling the printer's memory.

PostScript and PCL
