Filed under: Computer

Computer problems are ones users encounter all the time. Although technological innovations have greatly advanced and the Internet has become an essential part of day to day living, computer problems seem to plague computers from all parts of the globe. You complain of slow start-up and shut-down processes, a virus in your system file, memory glitches, and other software-related issues. The list goes on and on.

Luckily, you can find different troubleshooting tips that can help you detect the problems in your computer, attack and destroy them. These troubleshooting tips are vital pieces of information that will effectively fix your computer problems.

There are several websites that offer tips on how to repair computer. This site is one of those and the tips we have for you are simple, easy to follow, and tried and tested.

Unknown to some computer users, most of the computer problems you encounter is caused by software-related matters. In order to avoid software-related computer problems, it is highly recommended that you update your applications, drivers and operating systems by having their most recent versions. Have a list of the software and hardware you’ve installed in or on your computer over time and search for their updates, as well as new services, patches and bug fixes available in the market. Getting updates will also help you avoid software conflict, in which one application works only when another remains unopened.

Check for viruses. This is perhaps the golden rule in maintaining the top performance of your computer; it’s the most commonly suggested tip on how to repair computer and it makes sense. Viruses wreak havoc all over your system files and, before long, will damage your computer for good. Prevent this by getting antivirus software to do the tough job of detecting and destroying viruses. Also be mindful of malware. The most notorious of this kind of computer problem are spyware and adware, for which antispyware and antiadware should be used. You can also run a scan on your computer to find viruses and malware, and keep the virus definition files updated.

Uninstall and reinstall programs or applications that have not been in use for a long time. Most people have the idea that cleaning up memory and space means simply deleting programs, applications and files. It’s not that simple. These things are interrelated and removing one may render the others useless. If you’re not careful, you could create one messy web in your computer. To avoid this, what you can do is to keep track of the programs, applications and files that you haven’t touched for a while. You must uninstall these programs, applications, and files and then reinstall them. Get their updated versions while you’re at it. If you’re highly adept on how to repair computer, you can individually reinstall files, so you’ll be able to tell and reinstall only those files that don’t cause any trouble to your computer.

With these troubleshooting tips, your computer will soon be working like new.

Upgrade to a Color Laser Printer

Filed under: Computer

I have taken the cheapest current model from the following manufacturers for comparison, Canon, Epson, HP, Konica Minolta, Lexmark and Samsung.

Let’s get the technical bit out of the way first; colour laser printers come in two distinct engine types. The carousel type printer uses for different colour toner cartridges that rotate over a central drum unit, laying down each colour of toner in turn and making a total of four passes over the drum or imaging unit. Epson, Konica Minolta, Lexmark and Samsung all use a variation of this technique. Canon and HP cartridges come in one complete unit per colour that contains both the toner and drum giving each colour its own drum as opposed to sharing a central unit.
So which system is best? There is no correct answer to this question although I personally favour the option used by the Canon, HP duo. With this system there is no uncertainty as to how long the drum will last, it is replaced with every new cartridge. With the carousel system the life of the drum can be dramatically reduced from quoted figures if the colour content of your output rises over the standard 5%. The more colour printing you do the more passes over the central drum unit, the greater the wear on the unit and the more often it will need to be replaced.

If you are replacing an ink printer it is worth bearing in mind that these colour laser printers are somewhat larger, heavier and noisier, so if desktop space is tight check out the dimensions before committing to a purchase.

The smallest, lightest and quietest colour laser printer is the Samsung CLP300, when it was originally introduced this was probably the cheapest colour laser printer on the market and thus an argument could be made for its purchase. Times change very quickly in this market and a sub £90 price is no longer bargain basement territory. If you only intend to print colour text and charts then it will perform well enough but the quality of any colour output beyond this will I fear disappoint.

Moving to the dearest will give us the Lexmark C500N. This printer is almost twice the price of the tiny Samsung and in true Lexmark style is also the most expensive to run, in its favour it is network ready and has the fastest mono speed but this does nothing to compensate for its high costs.

The Epson AcuLaser C1100 has been one of my favourite colour printers since its introduction, it is still one of the fastest printers of its type and print quality is still above average, I feel however that it is now getting a little long in the tooth and the new Konica Minolta Magicolor 2530DL now offers several advantages. With an ethernet 10/100 base TX interface for networking and Pictbridge via a special USB on the front for downloading direct from a digital camera this has moved the goalposts and it tries to replicate ink printer facilities closer than seen before on colour laser printers. The standard 64mb Ram is also twice that on offer from the Epson and should ensure capable handling of even the most complex colour work. Whilst print quality is above average, the printer speed, especially for colour disappoints and is this printer’s major flaw. Be aware also that both these printers are delivered with low capacity cartridges offering only 1,500 colour prints, these will require replacing all too soon. The upside is that high capacity cartridges are readily available and offer better value with a capacity at around 4,500pages.

That just leaves the HP Color Laserjet 1600 and the Canon i-Sensys LBP5000 to be considered. Both of these printers use the same Canon engine so it comes as no surprise that the specifications match with a print speed of 8ppm and a print quality of 600x600dpi. Neither of these printers has an abundance of memory with the HP the most generous at 16mb, the Canon’s 8mb is particularly stingy and may struggle to cope with very complex colour work. The other main difference is in the price, the HP printer can easily be found online at a price under the magical £100 mark whereas the Canon at £50 more is competing with the HP’s big brother, the Color LaserJet 2600. As is the norm the printers are shipped with starter cartridges which give a maximum yield of 1,000 pages and will need to be replaced fairly quickly, fortunately both HP original cartridges and compatible cartridges are readily available from around £120 for a full set of cartridges yielding 2,000 pages.

We have used HP laser printers in our own offices for many years and have always found them to be both reliable and economical, especially if compatible cartridges are used. We have noticed some criticism online of a problem with colour bleed with the HP Color LaserJet 1600, we have not been able to substantiate these claims and only a small number of users seem to experience it, I am beginning to wonder if the quality of the paper may be at fault and not the printer. We have tried using some fairly low quality paper in an attempt to replicate the fault but so far have not experienced any degree of colour bleed.
So, if you are looking for your first Colour Laser Printer, and do not want to spend a fortune, look no further than the HP Color LaserJet 1600 - a fine buy at less than £100.
