Advantages of Having an A3 Printer Scanner

There are many printers available in the market and each one has to decide based on what each of them offers. Most people will buy printers just for the sake o printing. However, the choice of printer depends on the kind of features the printer has. People choose the features that exactly match that of their needs. In this article, we will focus more on what an A3 printer and scanner can do that will make buyers want to choose one.

Let us first see its advantage in printing. The advantage that an A3 printer scanner has, coming from the name itself, is that it can print up to a maximum size of 17" x 11". This is the standard dimension of an A3 size. Not all standard desktop printers are capable of printing this size. This offers more benefits compared to other standard printers since you are able to print materials that will require larger paper sizes. Examples of these are newsletters, posters and banners. You also have the option to print documents that need more attention on larger paper sizes.

The next advantage of an A3 printer scanner is it can also scan documents. Not only is it able to scan documents, it is able to scan A3 size documents as well. This will be very helpful in occasions where you need to scan larger documents. If you want to scan documents like newspapers and posters, it will be convenient for you to use an A3 printer and scanner. One common use for it is to scan pictures. Considering that we are still transitioning from filmed cameras to digital cameras, there are a lot of people who still have pictures to be scanned. With an A3 scanner, you can put in more pictures and save time scanning. Then you can get a photo editing software and just crop the pictures.

Another advantage that an A3 printer scanner has over others is that it can act as a copier. Most printer scanners have this advantage. They have the option to directly copy a scanned document and print it in an instant. If it is a colored printer, then you have the added advantage of copying colored documents as well. This is a very handy capability so that there is no need to go out and look for shops that can offer large format scanning.

Apart from the advantages that A3 printer scanners have over standard desktop printers, they have disadvantages as well. These printers are larger than other printers are since they need larger areas to hold A3 paper. One disadvantage that printer scanners have over printers is that they need more caution when handling. This is because of the glass of the scanner. It is one of the fragile parts of printer scanners.

These are the advantages that A3 printer scanners have over ordinary printers. Other equipments also have additional advantages as well. If you take a look at all-in-one equipments, they have additional features like facsimile. These features are very ideal if you use these equipments in offices.

Mr. Johnson specializes in finding the best A3 printer scanner for personal and professional use. Choosing a printer that can print AND scan in A3 format is not something that should be taken lightly. The wrong choice will not only make your life more difficult, but it will also be a waste of your time and money.

Cleaning and Maintaining Your Printer - How to Prevent Your Printer From Having an Off Day

Printers these days have been engineered to such a point where the slightest speck of errant dust can be the hairs breadth difference between smooth operation and professional documents or sayonara to the skip bin.

With that in mind, and noting that the current cost of most high performing office machines now exceeds New Zealand's GDP, a few small but invaluable procedures could save your pocket, your business and your sanity far more than the 5 minutes of precious time it will take to service that old faithful printing thingamajig.

Inkjet Printers

Some tools required when cleaning an inkjet printer, laser printer and cartridge etc. are a micro-fibre cloth, paper towel, cotton balls, cotton buds, isopropyl alcohol and an air compressor.

Below are a few steps to ensure your Inkjet Printers smooth operation and longevity.

1. Do not allow your printer to entirely run out of ink. In some inkjet printers the ink is also the lubricant for the print head.

2. Regularly check print-head nozzles. For Windows Users this can be done by clicking Start => Control Panel => Printers and then by right-clicking on your printer and selecting "Printer Properties". Select the Maintenance Tab and click "Nozzle Check" If any nozzles are blocked perform a cleaning procedure.

3. At least once a week clean print head. For Windows Users this can be done by clicking Start => Control Panel => Printers and then by right-clicking on your printer and selecting "Printer Properties". Select the Maintenance Tab and click "Cleaning"

4. At least once a month align print head. For Windows Users this can be done by clicking Start => Control Panel => Printers and then by right-clicking on your printer and selecting "Printer Properties". Select the Maintenance Tab and click "Print head Alignment"

5. At least once a month remove the ink cartridges entirely from the printer and manually inspect the internal working components. Some inkjet printers require the power to be on to remove the ink cartridges and make sure the printers power source has been turned off upon completion.

6. Now you have removed the cartridges be careful not to touch the metal components if yours is a cartridge which has the print head built into it. Wipe the excess ink from the print head of the cartridge by pushing the ink side down firmly onto some paper towel. Once cleaned place in a secure place until ready to be reinstalled.

7. Some printer heads can also be removed entirely and cleaned with paper towel and isopropyl alcohol. If this is not the case, where the cartridges dock you will see excess ink and fine particle paper dust. Use a cotton bud dipped in isopropyl alcohol to remove as much of this as possible.

8. With the printer still open check for paper fragments, ink, dust and any other fine particles that do not belong there.

9. Use a dry micro-fibre cloth to carefully wipe the other accumulated ink, dust etc from inside the printer. Do not use paper towel for this procedure. If you have access to compressed air a gentle clean can do a great job clearing the fine particle dust inaccessible with a cloth.

10. Once you are satisfied with the internal clean it will not hurt to also give the external casing a thorough wipe down with a micro-fibre cloth and compressed air if available.

11. Finally there is one more piece of advice as far as inkjet printers go and it is also quite controversial. DO NOT TURN THE PRINTER OFF IF YOU DO NOT HAVE TO.

Printers generally use minimal electricity and by leaving the printer on it is able to cycle the ink at the appropriate intervals preventing the print heads from clogging.

Also when you first turn on an inkjet printer it usually performs a clean which not only wastes ink but this excess ink will be absorbed by waste pads beneath the printer and once full will cost more to repair than it will to replace the entire printer.

If you absolutely must turn the printer off do so from the power button. The printer will go through a shutdown phase clearing the residual ink and closing the heads to mitigate the chance of clogging. Turning a printer off at the power point bypasses this important procedure.

Laser Printers

Each specific laser printer includes an instruction manual and a section on how to clean and maintain and should be followed at all times. However there are some procedures which are generally universal and can be applied to most laser printers when in the process of cleaning.

Some tools required when cleaning an inkjet printer, laser printer and cartridge etc. are a micro-fibre cloth, paper towel, cotton balls, cotton buds, isopropyl alcohol and an air compressor.

Never attempt to clean your laser printer while the power is still on and ensure machine has cooled down before proceeding.

Below are a few steps to ensure your Laser Printers smooth operation and longevity.

1. Before cleaning gently remove the toner cartridges from machine and carefully wipe with a dry micro-fibre cloth and place aside.

2. Remove paper trays and wipe these and paper tray bay clean with a dry micro-fibre cloth.

3. Clean empty cartridge compartment with dry micro-fibre cloth taking particular care not to damage any wires or sharp edges that are exposed. (Corona Wires etc.)

4. Dampen a cotton bud with isopropyl alcohol and clean the Corona Wire by gently running it along the top and underside being careful not to apply any pressure.

5. Clean the transfer roller and fuser assembly with a dry micro-fibre cloth. Be careful not to touch the transfer roller with your fingers as oil from your skin may damage it.

6. If you have access to compressed air now is the time to apply a low gentle flow which will clear the fine particle dust inaccessible with a cloth.

7. Once you are satisfied with the internal clean reinstall the toner cartridges.

8. Clean the external casing with a slightly dampened micro-fibre cloth and compressed air if available.

9. With compressed air and a dry micro-fibre cloth clean paper feed rollers which can be accessed from the rear and once complete reinstall paper tray.

10. Finally perform a test print to ensure all is well.

Apologia Science Curriculum - Having Fun With Lasers

Lasers remind us of Star Wars and parties. Lasers are associated with fun and although many other educational programs such as the Apologia science curriculum have touched the surface, I want to delve deep and enable kids to safely experience lasers and their diffraction.

    

L.A.S.E.R. stands for Light Amplification by Simulated Emission of Radiation. The light emitted by an incandescent bulb spreads in all directions, and therefore lights up the room, while the light coming from a laser is in the form of a thin beam made up of photons travelling in a straight line. Therefore a laser beam makes just a dot of light on your wall. I have gone through many homeschool curriculums such as the Apologia science curriculum, and I felt that I must take learning one step ahead by introducing some practical and fun ways of learning science.

 

How Lasers Work

When a light source throws light into the tube of your laser pointer, the particles of gas in the tube begin to vibrate harder (imagine your excited pet dog running all over your living room). When these excited particles relax (imagine your dog lying lazily on the couch), they release light energy in the form of photons. These released photons now collide with other gas particles in the tube and make them vibrate or relax. After some time many photons of light are released. They bounce off mirrors in the tube and are released through the opening of the tube (imagine a doggie door) in a controlled manner, forming a thin and straight beam.

 

Now let's do a couple of fun experiments. You can use a keychain laser or a simple red-laser pointing device for the same. Green lasers from astronomy stores are dangerous and should not be used. Remember to wear eye protection even if it feels weird to wear them in the dark.

 

Beam through Bottle Experiment: Fill a plastic soda bottle with water. Add a few pinches of cornstarch till the water turns slightly milky. Now switch off the lights and flash your laser pointing device through the bottle. What do you see? Do you see the original laser beam? Can you find the reflected and the pass-through beam?

 

Laser-Fog Machine Experiment: You can do a slight variation to the above experiment by using a fog machine instead of cornstarch water. Turn on the fog machine and flash a couple of laser pointing devices through the fog. Enjoy the spectacular laser show!

 

CD Laser Diffraction Experiment: Place an old scratched CD and a new smooth CD on a table. Turn on the fog machine around the CDs, and flash the laser pointer on both the CDs. What do you see? Which CD sends out more reflections, the scratched one of the smooth one? See to it that there is enough fog so that the laser beams are seen clearly. You can also place other shiny objects near the CDs and enjoy the laser patterns!

 

Homeschool science can be really cool, and I want to take you beyond your Apologia science curriculum experience. Click the link below to check out the free "Homeschool Parent's Guide to Teaching Science", for more great science experiments and activities.

A great free resource for really cool science activities and experiments is to download a copy of the Homeschool Science Experiment Guide.

Another good homeschool resource for science ideas, experiments and activities, is the homeschool science blog (just click on the "Blog" link). Definitely worth bookmarking.

Good luck!

Having Family Fun With Science Projects

Does your family need more time doing something educational but also to be fun and hold their attention as well? Well here are some ways that your family can do something together, have fun, and even have it be educational all at the same time. Below are some ideas on how to have family fun with science projects.

Family time is very valuable. You want to make sure when you are picking a science project for your family to make it something that will be fun for everyone. You want to make sure to pick something that everyone will be interested in and want to learn more about. This will help assure that all of the family will have a good experience and want to do science projects together more often.

The following are four reasons your family will have fun doing science projects:

1. You interact. You have to talk, theorize, and make decisions, which can create great memories.

2. It is hands on. Unlike watching television, science projects require thinking and action. As a family, you can work together to figure out how something works, test a theory, or build something. It is a great time to bond, and get off the couch.

3. You learn. Who said learning isn't fun? The truth is, when you learn through application it is a lot of fun. Seeing the results of mixing two colors to create a third, or creating a real erupting volcano can be lots of laughs, excitement, and amazement.

4. Your family will spend time together. When a family does a science project together they are working together for a common goal and having fun. What could be better?

One idea for you to try out for family fun with science projects is making soap. There are different ways you can make soap with different ingredients. You can look online and see what different ingredients different soaps use. You could also do a little lesson involving bacteria's and different ways of getting rid of bacteria and germs using soap. This will help your family have fun with science projects and help them to be a little more educated all at the same time.

The second idea for family fun with science projects is making a lava lamp. This can be done by taking water and sticking it into a glass jar. Then add food coloring in the water and mix it together. You take vegetable oil and pour it into the water in the glass jar. Then wait for the oil and water to settle. The water and oil should separate. Then take a salt shaker and shake salt into the oil while counting for five seconds. The salt and oil mixture should sink to the bottom in a clump. As the salt dissolves the oil should float back up to the top. To make the oil go back down to the bottom shake some more salt while counting to five again. You can also use this as a lesson on the laws of gravity.

The third idea for family fun with science projects is to create a funnel like a tornado would make. Do this by giving everyone in the family their own 2 liter bottle with a funnel. Take the funnel and place it in the top of the 2 liter bottle. Then take a pitcher of water and pour it into the funnel to fill up the 2 liter bottle. Do not fill the bottle all of the way up. Then put the lid back on. Then have your family shake the bottle clock wise around and around and then have them stop. This motion will cause the water to spin like a tornado would. You could do a lesson on tornados and what they do and then have this project to go along with it.

There are so many things out there that you and your family can have fun while doing science projects. It doesn't matter what kind of science project you do it is all about the information and discussions given. Showing your family that you are interested in science helps them want to be more involved and will help them be more interested. Ask questions and give answers that will help your family to understand science and the meaning behind the experiments you do. This will help them to remember what they need to know about different science experiments. So take your family and go have some fun with science projects.
