Describe the exposing or writing step of laser printing. Your Answer:
1. Processing the image - A laser printer processes and prints an entire page at one time. The page comes to the printer encoded in a printer language and the firmware inside the printer processes the incoming data to produce the bitmap of the final page, which is stored in the printer's memory. For color images, one bitmap is produced for each of four colors blue, red, yellow, and black. (Better known as cyan, magenta, yellow, and black, and sometimes written as CMYK) 2. Charging or conditioning - The drum is conditioned by a roller that places a high uniform electrical charge of -600 V on the surface of the drum. For some printers, a corona wire is used instead of the charging roller to charge the drum. 3. Exposing or writing - A laser beam controlled by motors and a mirror scans across the drum until it completes the correct number or passes. For example, for a 1200 dots per inch (dpi) printer, the beam makes 1200 passes for every one inch of the drum circumference. 4. Developing - The developing cylinder applies to toner to the surface of the drum. The toner is charged and sticks to the developing cylinder because of a magnet inside the cylinder. A control blade prevents too much toner from sticking to the cylinder surface. 5. Transferring - In the transferring step a strong electrical charge draws the toner off the drum onto the paper. This is the first step that takes place outside the cartridge and the first step that involves the paper. The soft, black transfer roller puts a positive charge on the paper to pull the toner from the drum onto the paper. Very thin paper can wrap around the drum, which is why printer manually usually instruct you to use only paper designated for laser printers. 6. Fusing - The fuser assembly uses heat and pressure to fuse the toner to the paper. Up to this point, the toner is merely sitting on the paper. The temperature of the rollers is monitored by the printer. If the temperature exceeds an allowed maximum value (410 degrees F) the printer shuts down. 7. Cleaning - A sweeper strip cleans the drums of any residual toner, which is swept away by a sweeping blade.
Describe how an inkjet printer works. Your Answer:
1. Uses a type of ink-dispersion printing. Doesn't provide high-quality resolution of laser printers 2. Print head moves across paper. One line of text created with each pass 3. Print head moves across paper. One line of text created with each pass 4. Different types of inkjets form droplets of ink in different ways. Most popular is the bubble-jet 5. Includes one or more ink cartridges to hold different colors of ink 6. A stepper motor moves the print head and ink cartridges across the paper using a carriage and belt to move the assembly and a stabilizing bar 7. Some inkjet printers offer duplex printing. Be sure to use heavy paper so ink doesn't bleed 8. Inkjet printer buying advice. Printer using two or four separate cartridges 9. Software may be used to clean inkjet nozzles and calibrate/align cartridges. How to access tools differs from one printer to another 10. If inkjet printer still does not print after calibrating it. Cartridge nozzles may have to be manually cleaned 11. Laser printers automatically calibrate themselves periodically

When looking to install a hypervisor, what considerations should be made for the motherboard? Your Answer:
A hypervisor is a thin layer of software that resides between the virtual operating system(s) and the hardware. A hypervisor allows virtual machines to interact with the hardware without going through the host operating system. A hypervisor manages access to system resources such as: • CPU • Storage • RAM Commonly used hypervisor types include: • VMware Workstation and ESX (made by VMware) • Hyper-V (made by Microsoft) • XEN (open source) • Oracle VirtualBox • Kernel Based Virtual Machine (KVM)
Compare and contrast local versus network printer. Your Answer:
A printer connects to a single computer or to the network. A local printer connects directly to a computer by way of a USB port, parallel port, serial port, or wireless connection (Bluetooth, infrared, or Wi-Fi). Some printers support more than one method. A network printer has an Ethernet port to connect directly to the network or uses Wi-Fi to connect to a wireless access point. Some printers have both an Ethernet port and a USB port
