: Connect hardware peripherals Part one
- 1. UNIT THREE: CONNECT HARDWARE PERIPHERALS Coverage topics 1. Considering environment and OHS Standard 2. Removing and replacing old peripherals 3. Configuring operating system 4. Testing and conforming hardware peripherals
- 2. Considering environmental and OHS standard • environmental consideration like dust, temperature, humidity, electric system, working tables • When installing software it take time ,the client may not be happy due to urgent report • Occupational health and safety (OHS)a way of improving workplace health and safety standards • give advanced notice • It is important to schedule installation time and OHS standards that are: - • Also suitable to the client’s or computer user’s • Sufficient length to install and thoroughly test the hardware device and • Create attractive working place for the clients • schedules the client and Before or after normal office hours
- 3. Removing and/or replacing old peripherals • backup any system files changed during installation ‘readme.txt/ file contains. • Connecting Peripherals • Connect the hardware • Install the software drivers • Test the peripheral • Peripheral Software Drivers • Driver software: allows computer to recognize new hardware • windows have it for common hardware e.g., modem • if comes with ‘disk’ use it as it is more recent • if on internet check ‘readme.txt’ file first – latest drivers • peripheral manual guides to installation process OR ‘control panel’
- 4. 3.3 Configuring operating system to accept the new peripherals • It is important to refer to manufacturer guidelines and manuals when installing any hardware device due to each peripheral device will have its own individual installation procedures. The procedure are • Plugging in the cables between the device and computer system • Installing driver software for configuration • Troubleshooting device installation when necessary • Customising the device and updating drivers • Testing the device for satisfying required conditions of clients
- 5. • To install a hardware peripheral device we need to install a driver depending on types of devices • A device driver is a software program that allows the hardware device to talk to the operating system and create an interface between users and devices • It is a good idea to check the manufacturer’s website to see if any new drivers have been developed for the specific peripheral devices. • Plug and play is a hardware technology that enables many operating systems to automatically recognize new hardware devices and configure them automatically. Eg USB
- 6. • Before connecting all the peripherals to its corresponding ports, check it that the power cord was unplug into the power source to prevent electrical related injury. • You should be able to connect the Mouse, Keyboard, Monitor, Printer, Scanner, Speaker and power up your computer by connecting the power cord to the power supply. • To connect the scanner , mouse , keyboard to the PC, you can use the USB cable.
- 7. Connect the printer to pc • Step1. Obtain the correct printer cable • To connect the Printer to the PC, you can use the cable via printer port or A USB to connect the new printer to the computer especially the colored and laser printer. • In many cases a printer won’t automatically have a cable included with the original purchase. • Check the printer specifications; you will probably need to buy either a parallel or USB cable.
- 8. Step2. Plug in the cable • Turn off the power of both printer and computer system • Plug the printer cable into the correct port of the computer • Steps3. Install ink cartridges of printers • install an ink cartridge (for inkjet printers) or toner cartridge (for laser printers). • Turn the computer’s power on and follow the manufacturer’s guidelines to install a new cartridge
- 9. Steps4. Install the printer driver • At some point the computer will either recognise that new hardware has been installed (for example if the operating system is plug and play compatible) or you will need to tell the computer that a new device has been added. • Sometimes the installation CD will automatically run, installing the printer driver at the same time.
- 10. Steps5. Print a test page • quickly determine if the printer is working correctly. If not you can troubleshoot the installation.
- 11. Customizing the printer • Depending on your client’s needs, alter the default printer settings. Eg : • Changing the page layout: alter to either landscape or portrait orientation. • Changing the paper source/size • Changing the print quality • Setting the default printer: - if there is more than one printer attached to a computer, you may need to change the settings so that the newer model is considered the default model
- 12. Testing and confirming hardware peripherals • In addition to a device perform a basic task all functionality required by the client is must be tested before use to work • Printer functions that may be tested are: • Can the printer handle different paper types? • Will the printer work successfully on different computers? • Will the printer work successfully with different software packages (for example, word processing, spread sheets and desktop publishing)? • Is black and white print quality acceptable to clients? • Is colour print quality acceptable to clients?
- 13. 3.4.1 Test plan • A test plan is used to work out a structured process to ensure that a new device will work under all expected circumstances. It logically describes: - • Functions that need to be tested • An example test case scenario • Expected results for each scenario
- 14. Operation Sheet 3.1 adding local printer • Operation title: Add a local printer • Purpose: To connect printer and computer for printed documents. • Instruction: Use the given step below appropriately. For this operation you have given 30 minutes and you are expected to provide the answer. • Tools and requirement: • Computer • Divider • Printer • Paper • Printer data cable or crimped network cable • Precautions: before starting computer identify and plunge the correct peripheral and check printers to get power.
- 15. Procedures • Step 1: - Connect the printer to your computer using the USB cable and turn it on. • Step 2: - Open the Settings app from the Start menu. • Step 3: - Click Devices. • Step 4: - Click Add a printer or scanner. • Step 5: - If Windows detects your printer, click on the name of the printer and follow the on-screen instructions to finish the installation. And you're done. • If Windows doesn't find your connected printer, click on "The printer that I want isn't listed" link.
- 16. • Quality Criteria: final print test pages and print any documents as you went. • Lap Test 3 • Task 1: install printer driver to communicate with computer and print test page? • Task 2: Print any document as you want? • Task 3: Remove and replace old internal and external hardware peripherals based on organizational policy?
