Do you have an inkjet printer at home? If yes, I'm sure you know the cost of purchasing an ink cartridge or inkjet cartridge. Just in case you are not able to figure out which part of the inkjet printer I'm talking about, an ink cartridge, or inkjet cartridge, is a standardized interchangeable part of an inkjet printing machine that comprises of the ink. Each ink cartridge comprises of one or more than one separated ink sources.

Purchasing a new ink cartridge can burn a hole in your pocket, particularly if you do a lot of printing work. Fortuitously, almost all of the printing machine producers have built up refillable ink for ink cartridges. Oftentimes you can economize up to 50% or more than that over a new replenishment cartridge. Ink jet replenish kits hold in very simple to apply tools and directions for the filling again of an ink cartridge. Following are the back-to-back directions for setting up your ink cartridge or inkjet cartridge for a refill.

01 - Purchase an ink replenish kit from your local computer shop. As I said, almost all of the printing machine producers have built up refillable ink for ink cartridges, you can easily get one for the printer you own.

02 - Once you have the ink repllenish kit, get together all of the stuff that you will necessitate to replenish the cartridge. This can comprise of an injection syringe, a pair latex gloves to protect your hands, clear-tape, and paper-towel.

03 - Now withdraw the exhausted cartridge from your printing machine. Reckoning to on what kind of printing machine you own, there will be a unique procedure of cartridge remotion. Please look up to your printing machine guide on how to replenish a particular kind of ink cartridge or inkjet cartridge.

04 - Position the exhausted cartridge on a piece of paper-towel so that the floor or the surface does not get dirty with the ink in case there is a leakage. Also make sure that your hands are covered with latex gloves.

05 - Now that the your hands are safe, please look for the filling holes on the upper part of the cartridge by slipping your thumb crossways on the label. Unless you find the filling holes, you won't be able to replenish your empty cartridge.

06 - Now that you have located the filling holes, utilize a pencil or a tooth prick to puncture or open the filling holes on the upper part of the cartridge. Once the holes are open, you will be able to fill the ink.

07 - Now its time ti fill the ink. For this you will need an injection syringe. Make sure the syringe you are using is not very small in size. Introduce the extended needle of the syringe into the refill ink container into the right hole. Also make sure that you use a different syringe for a different ink type. There are two ink types - black and colour (Magenta, Cyan and Yellow).

08 - Bit-by-bit, add the ink. Again I tell you, add the ink bit-by-bit in small quantities. It is essential to make for certain that you do not fill more ink than required otherwise it will spill out. It is commonly 10 cc for black ink and just about 5 to 8 cc for colored ink. You can measure the quantities with the help of the syringe.

09 - Cease instantly when you find out ink flowing out of the filling hole. Withdraw the needle from the filling hole after discharging any leftover ink. Please makesure that you do not over-fill your cartridge.

10 - Cautiously tap the cartridge impinging on the paper-towel to find out if there is a pick out of ink which means there is a leakage of  ink. As such there are very less chances of leakage however, if a leakage is there, the cartridge cannot be used anymore. Mis-handling of the cartridge can cause leakage.

11 - Hide the filling hole with a little patch of clear-tape. This is to make sure that the ink that you just filled does not come out of the holes. Also make sure that you do not shift the colours. If you do, its obvious enough that you will not get good quality prints.

Replicate the same procedure for every ink color. On phat point are three ink colours as already said -  magenta, cyan, and yellow. Please follow the directions on which hole to enter which colour. If you are not able to nake it out, the tooth prick will come handy. All you need to do is, just press a tooth prick inside the holes to find out the colours as the marks on the printer cartridge. As already said, make sure that you do not shift the colours. If you do, its obvious enough that you will not get good quality prints.

12 - Now that you are done with the replenishment, its time to install the cartridge back into your printing nachine. So go ahead and place the ink cartridge or the inkjet cartridge back into your printer.

13 - Allow the ink cartridge to remain inside the printing machine for around 10 to 12 hours ahead of employing it to get print-outs. This will allow the little piece of sponge within the cartridge to turn well drenched with the ink that you have filled.

14 - Now that everything is done, its time to employ your printer to print different test pages in order to examine and make sure that the ink is running or there is some problem. In 99 out of 100 cases you will never encounter a problem with the method I just taught you. In rarest of rare cases you will find that the prints are not up to the mark which implies your cartridge has gone bad and replenishment won't work.

There are a so many of distinct procedures to replenishing your ink cartridge or inkjet cartridge. The profits of replenishing is that it is practically cost you much lesser than just throwing away the expended cartridge and purchasing a brand new cartridge. Another major benefit of replenishing the cartridge in this way is that keeps the toxic ink out of the environment. Most people ignore the fact that toxic ink will spoil the soil as hazardous chemicals are used in the manufacturing of ink. You also will serve scale down the add up of scraps and waste material going into the land-fill. So the next time your printing machine runs out of ink, please consider buying an ink replenish kit and try replenishing the cartridge. It saves money, it saves environment. Also make sure that you do not waste paper as it is made at the cost of trees. Think before you print.

Check and measure various power supply voltages of pc

$~Theory ~$

The PC power supply is primarily designed simply to take AC from the wall outlet & convert into the much lower DC voltages needed by the system. When system shut down, it must prevent any voltage overshoot & fluctuations so that none of sensitive circuits are exposed to any damaging voltage fluctuation .It must include some way of providing cooling air flow, because of the conversion process always has some heat by product.

$~Converting AC to DC power~$

Figure ~ Liner ModePower Supply

Figure~ Switching Mode Power Supply

$~ Output voltage supply voltage lines ~$

The voltages delivered by the power supply to the motherboard must remain stable in spite of a wide range of input AC voltage and varying load conditions

$~ +5 volt supply ~$

This is the basic supply voltage for nearly all-electronic components. The 5V supply is now sometimes used by motors, but usually only in smaller drives, such as “2.5inch” & some 3.5inch drive. The  +5V supply wires should always be red in any standard PC system.If regulated voltage is adjustable, the jumpers or switches will probably be found near regulator circuit.

$~ +12V power supply ~$

This line supplies most if not all, motors in the system, from drive motor to cooling fans. Because motors often used up to 50% more power on start up then while running ,the +12V supply may show adequate operation  while running , but be in an over loaded condition during the 5 seconds or so immediately .after the system or a particular drive is turned on .

$~ -12 V power supply ~$

This supply line is usually used for some of the same communications circuits that   use  +12 V line.

$~ -5 V power supply ~$

This voltage is no longer used by any device and is retained only the purpose of backward compatibility with the older ISA slots.  Originally, this voltage was used by some DRAM memory chips in original PC design. Micro channel system omitted this voltage from the power supply entirely

$~ +3.3V power supply ~$

Starting with the ATX designed in 1995 any system with  ATX compatible power supplies include a 3.3 volt supply line from the power     supply to the motherboard. Currently most CPUs & DRAM used 3.3V as well as some PCI adapter cards.

$~ Power Supply Control Signals ~$

Although the primary function of the power supply is indeed to supply clean electrical power to systems, the power supply also interacts with the motherboard to perform an increasing number of functions, including CPU startup, system power down, voltage and temperature detection and other functions.

$~ Power Good Signal ~$

The signal is actually a logic level signal designed as a power supply output signal to the CPU circuitry, to start the CPU running.

$~ Power On ~$

Prior to the ATX standard, AT compatible power supplies either had the power switch mounted on the back or side of power supply itself ,or had a remote switch mounted on the front panel.
The power on signal wire is apart of ATX standard and carries only a low voltage logic level signal from the motherboard to the power supply, telling it when to turn on and when to turn off.
