Printer Issues

     Printer is a device that converts the text that we type on the computer into a physical form either it becomes in a paper or any other media. It has become one of the important devices that computer users ought to have nowadays. Printers have played an important role for people. However, there are some printer issues that are happening such as health risks, printer problems,etc. Below are the detailed printer issues and some types of printers.

Types of Printers

Dot-Matrix Printer

     Dot-Matrix printer produces a quite similar letter-quality type. It uses ribbon for the ink. It has advantages of low-priced, has a low maintenance cost, low-priced ink costs, reliable and durable. But on the other hand, it has limited color printing, noisy sound that may distract users, low printing speed and has also a low resolution.

Inkjet Printers

     Inkjet printer is the most common used at home and it has also a good resolution. Inkjet printers use ink cartridges for printing. They are low cost, fast, quieter if compared to dot-matrix printers and require less space to put. However, the ink cartridges are yet expensive, it may cause a mess when the ink bleeds and less quick than laser printers.

Laser Printers

     Laser printers are commonly used to print in a large amount of printings. They are known as the fastest or quickest printers compared to others and make use of Toner Cartridges for printing. This kind of printer is very efficient, it produces less sound, a good quality of printing and relatively a light weight. But then, due to the advantages, laser printers are expensive and known to be quite dangerous because of the ozone that is produced. It is even said that laser printers can damage lungs like how cigarettes do.

  

3D Printers

     3D printers are the newest type of printer. They create a 3D object by using plastic or nylon thread. The merits of 3D printers are affordable price of printing, low production cost and eco-friendly as they only have a very minimum amount of waste. The demerits are the limitation of the raw material needed and dangerous printing weapons that may harm our body.

Health Risks

     Below are the possible health issues that are created by printers and some tips to prevent.

Ozone

     

     Ozone is commonly found in photocopiers and laser printers. They may affect our health through our respiratory system and eyes. Ozone is also produced by industrial activities that involve UV radiations.

Respiratory Health Risks

     Respiratory health risks such as asthma may also occur as the result of the use of printers. This may occur especially in laser printers which increase the concentrations of styrene (hazardous chemical that affect the eyes and skin when inhaled) and xylenes (flammable compounds). Inhaling the ultrafine particles produced by printers results from respiratory irritations to more deadly illnesses such as cancer.

Tips

A Ventilated Area

     Ensure that you prepare a ventilated area for your printer so the dust created will not affect your health. Regulating air qualities is also one way to prevent.

Be Aware when Changing Cartridges

     Be very aware if you are changing the ink cartridges for printers especially if you have asthma or any other respiratory illness. Changing cartridges may cause respiratory problems or may worsen your problems. Cartridges may contain carbon black (a dust that possibly harm humans' health that is found in toner ink), overheating cartridges that may burn your skin or again, ozone dangers.

The Appropriate Workstation for Using Computer (Revision)

     The content of this blog is about the appropriate workstation for using computer This may sound insignificant to you, but the greatest wealth is health. Besides that, a comfortable and appropriate workstation affects your works too. So below are some tips for you to have the appropriate workstation in your house, office,etc.

     Adjustable Office Chairs

  Basically, adjustable means you can control or you can make it into what do you want it to be. By adjusting the perfect position of sitting, you can comfortably do your jobs. This kind of chair has a good backrest with a lumbar(curved lower back) support. It also has an adjustable backrest height for you to control the height of the chair that suits you. Studies show that the best position is actually the reclined 100-110 degrees not the upright 90 degrees that are usually portrayed.

     Chair Armrest

  Having armrest may be useful to aid getting into or out the chair. Ideally, armrests should be height adjustable and able to be turned inwards or outwards. We can also place our hands in the armrest when we are relaxing, taking a break from using the computer, texting messages or etc. Having an adjustable armrest is very useful because you can remove the armrest if you do not want it to be there, maybe while you are typing because it may distract you. Sometimes, you got a chair with a very low armrest or a too high armrest which may distract your comfort. Thus, it is important to have an armrest chair or even an adjustable armrest chair would definitely be a better choice.

     Seats with Backrests

  Seat with backrest is definitely a must. It may serve us with comfort. An adjustable backrest is obviously a better choice. An angle of 100-120 degrees will be the perfect spot for users. Backrests are also useful for users to relax themselves in between their works which use computers.

     Scalloped Desk

  Studies show that  compared with a straight edged desk for computer-based work, a 

scalloped desktop (which has a shallow curve cut out at the center) provides you more opportunities for forearm support, greater desktop space and better work postures.
