My Printer Not Connecting

Image
 If you are having an issue with installing a printer or getting other issues dealing with a printer or printer setup on the computer, try this troubleshooter.  If a step doesn't apply, skip to next step  1. Turn computer off  2. Turn printer off 3. Disconnect power to printer for 2 minutes  4. Turn printer back on  5. Wait one minute  6. Make sure all connections are good  7. If your printer has both parallel and USB connectors, only have one of the two connected and not both. The USB is faster. (most new systems do not have parallel connections)  8. Turn computer back on  9. Make sure the printer has ink  10. Is the printer networked? If so is it connected to the network via computer or router. If it is connected via a computer and the computer is off, the other systems will not see it.  11. Make sure the dependencies to the print spool is started  12. Check the manufacturer of the printer to see if there is a newer driv...

RESISTOR TESTING

Image
1- Visual inspection: Checks for missing or any burning on resistance.   2- Using Digital Multimeter: You can check the resistor resistance by selecting the ohm range in the digital multimeter, If the resistor is in circuit, you will generally have to remove the resistor so you are testing only the resistor value and not the other components in the circuit.   Connect test probes across the two points of the resistor as shown in the photo, polarity isn’t important, value of resistance shown is 9.86 kΩ. Note: All resistors have a specific tolerance rating. The tolerance rating is marked by a color band on the end of the resistor’s body, normally the band is gold indicating 5 % tolerance. If the tolerance band is silver, then the rating is 10 %. How to test SMD Resistors: Because of the small size of SMD resistors, there is often not room for the traditional color band code to be printed on them. Therefore, new resistor SMD codes were developed. The most commonly seen codes are t...

IP Address: internet protocol

Image
   What is an IP address?     An IP (Internet Protocol) address is a unique numerical label assigned to each device connected to a computer network that uses the Internet Protocol for communication.     It serves two main functions: identifying the host or network interface and providing the location of the device in the network. Types of IP addresses:     IPv4: This is the most common type of IP address used today. It consists of four sets of numbers separated by periods (e.g., 192.168.0.1). IPv4 allows for approximately 4.3 billion unique addresses.     IPv6: With the increasing number of connected devices, IPv6 was introduced to address the depletion of IPv4 addresses. It uses eight sets of numbers separated by colons (e.g., 2001:0db8:85a3:0000:0000:8a2e:0370:7334). IPv6 provides a significantly larger address space. How IP addresses work:     When a device wants to communicate with a...
