A: Yes & No. Actually Lexmark makes the the most of the inkjet printers and cartridges for the Dell. But the inkjet cartridges for the Dell inkjet printers are keyed Lexmark inkjet cartridge that will only work in a Dell machine. However, since most of the inkjet cartridges can be remanufactured or refilled, the "Keyed" part of the cartridge is usually engineered to be a universal cartridge which can be used for a Lexmark printer and/or a Dell inkjet printer.

Barcode Printers & Scanners - How does it work?

What is Barcode Technology and how does it work?

A bar code is a series of varying width vertical lines (called bars) and spaces. Bars and spaces together are named “elements”. There is a different combination to the bars and spaces which represent different characters in a bar code.

When a bar code scanner is passed over the bar code, the light source from the scanner is absorbed by the dark bars and not reflected, but it is reflected by the light spaces. A photocell detector in the scanner receives the reflected light and converts the light into an electrical signal.

As the Barcode Scanner is passed over the bar code, the scanner creates a low electrical signal for the spaces (reflected light) and a high electrical signal for the bars (nothing is reflected); the duration of the electrical signal determines wide vs. narrow elements. This signal can be “decoded” by the bar code reader’s decoder into the characters that the bar code represents. The decoded data is then passed to the computer in a traditional data format.

Some of the top Barcode Printers Manufacturers are: Zebra, Intermec, Datamax

Extending the Life of a Projector Lamp

These are simple and common sense tips to extend the life of a projector lamp.

During the use of a Projector
Keep the projector air filters clean. Clogged filters and/ or vents will not vent heat properly, and can cause the projector lamp to overheat and fail.

Do not place anything on top of the projector or in front of the intake or exhaust vents. This will cause the lamp to overheat and fail.

Some projectors now offer "low lamp" or "economy mode" options. Use them whenever possible. These options have been developed to extend lamp life.

Turning off a projector
Do not unplug the projector until the lamp has properly cooled. After the projector has been shut off, the fan will remain on for about 5 minutes. This aids in cooling the lamp evenly and completely and decreases the chance of early lamp failure.

Hot projector lamps are very fragile. Only move the projector after the lamp has completely cooled. The shock and vibration while in travel to a hot projector lamp may cause the lamp filament or the bulb itself to break.

Do not turn the projector on and off frequently during presentations. Each time the projector is switched on, the inrush of power causes stress on the lamp filament. Try to minimize on/ off cycles.


Replacing a Projector Lamp
Handle the lamp with gloves. Oils and deposits from hands and fingers can cause hot spots, which may result in early projector lamp failure.

When you replace the lamp housing, make sure the new housing is seated completely. Apply pressure at the base of the housing until it is completely secure.
