The most daunting experiences of possessing a car is when you need to replace or repair a broken windshield. Windscreen replacement is not for the faint of heart; it requires strength, a pair of stable hands, and a willingness to follow instructions cautiously.

Every car is different, but in general, removing a windshield requires loosening the urethane that holds it in position, then carefully lifting it out of its position so as not to drop and shatter it. Next, the leftover urethane must be cleared away with a utility knife to make room for the windscreen replacement. The new windscreen is then glued into place, and enforced with bolts. When replacing a windshield, it is very important to make sure that the new urethane seal is put in place properly, because any leaks can cause wind to get into the car, totally ruining the experience of driving.

You do not always need to replace your windscreen if it has a chip, it may be possible to repair it instead of replacing it. windscreen repair is a considerably simpler procedure. Repair kits are sold by nearly every auto parts store, and involves sealing off the chip with resin. The resin the clear and does not leave a mark, and once the process is complete, it is virtually impossible to distinguish that the windshield was ever damaged. Windshield repair kits can be unreliable when used to fix large cracks, however, and can sometimes make the problem worse, needing a replacement. This job is often better left to professionals.

If you decide to let a professional deal with your windshield problems, you may be delighted to find that very often you do not need to bring your car to the garage. Many companies offer mobile repair services, which can be completed in a matter of an hour or less, even if the windshield requires to be replaced completely. Mobile windscreen repair services are able to perform the service at the comfort of your own home, or while you are at work, making it an extremely convenient one.

A good first-rate electric log splitter can be used in a personal workshop as well as by professional lumbermen who use them on the job sight for commercial work. wood splitters come in several varieties. Deciding on the one that’s right for your project or job can make a big difference in the long run.

The simplest hydraulic wood splitterthe basic splitting axe is all you’ll need for a few piles of firewood now and then. The log splitting axe blade cuts into the lumber and the wedge shaped log splitting maul head forces the wood to split along the grain. A couple of strong log splitting axe blows can split a log up to 25 inches long. Any person who doesn’t mind some solid exercise will find the regular axe to be the ideal tool.

Those who use a wood splitter on a daily or weekly basis, or for detailed home projects, spending the money on a hydraulic log splitter should be considered. Do you think you will need a horizontal or a vertical loading manual wood splitter for the type of work you do? This is a choice you’ll need to make. For on-site and outdoor use, log splitters with gasoline powered or diesel engines are available. Another option for those who have access to a power supply is to use an electric manual wood splitter.

Regardless of which type you choose, a manual wood splitter works with the use of a piston that drives the timber through a secured blade.

The best hydraulic log splitter is one that can get the job done fast and without mechanical complications. Although it can be a costly investment, the hours of manual labor saved make a electric wood splitter well worth the cost. Appropriate safety measures should always be taken to protect the operator from unnecessary injury.

Others should stand clear of the wood splitter when in operation. Protective eyewear should always be worn to avoid injury from flying particles of wood. Loose fitting clothing and jewelry are a safety hazard and should not be worn.

Independent contractors who work on homes or for those who remodel and use wood regularly, a manual wood splitter is a smart investment decision. From chopping firewood to making furniture, a hydraulic wood splitter can be used for numerous projects. Looking for a hydraulic log splitter? They can be purchased wherever other logging equipment is sold.

Background:

The main advantages of HDMI, high definition multimedia interface, over standard analog video transmission is that it is 100 % digital from source to display. However, transmitting HDMI over long distances is not so easy. In this article we will describe some of the issues encountered during HDMI transmission and present a solution that can significantly improve HDMI transmission: the HDMI Extender.

Basic HDMI transmission characteristics:

HDMI is based on TMDS, transmission minimized differential signaling, developed by Silicon Image. In order to support non-compressed HD video quality, HDMI needs to support data rates up to ~1.65 Gbps for each of 3 transmission pairs. In addition, TMDS is based on a characteristic impedance of 50 Ohms ( 100 ohms differential).

The math of HDMI signaling:

Although TMDS is a base-band “digital” signal, mathematically it can be thought of as a summation of harmonically related sine waves. The great French mathematician, Jean Baptiste Fourier (1768-1830), showed that any signal waveform including a square wave (think digital here) could be resolved into a summation of harmonically related sine waves. As the data rate of a digital signal increase, so does the frequency of the individual sine waves that make up the “composite” digital signal. For example, for a 50% duty cycle perfect square wave, the fundamental frequency (lowest frequency component) is of the data rate. In summary, a digital signal is simply composed of the fundamental frequency sine wave and harmonics of this fundamental sine wave. The amplitude of the individual sine waves is determined by Fourier transforms.

The challenges of HDMI signaling over long cables:
Transmitting high-speed HDMI signals is not easy because the frequency of the individual sine waves is such high frequency. As frequencies of the signal increase, the design of a good HDMI transmission product falls in the realm of good RF/microwave engineering. The challenges of high-speed digital transmission can be broken down to :

Attenuation: as frequencies increase, signal attenuation of the cables increases due to the “skin effect.” Essentially, the “skin effect” describes the phenomena that as the frequency of a sine wave increase, the wave tends to travel on the outer portions of the cable conductor. Whereas ordinary 60Hz AC signal might travel through the entire cross sectional area of the conductor, a high frequency may only travel along the outer edges of the conduct therefore the “impedance” to signal travel is greater. Think of this as a water pipe where the center of the pipe is blocked and fluid can only travel on the outer edges of the pipe. In addition, the attenuation of a cable increases with the cable length.

Intra-signal pair skew: recall that higher frequency sine wave also have shorter wavelengths. HDMI is based on differential signaling, therefore the “skew” ( any delay between a transmission pair ) of each the signal must be minimized. Any differences in trace/cable lengths will tend to skew the arrival time of the signal to the receiver. As frequencies and cable lengths increase, the errors will be more pronounced.

Impedance matching: : HDMI is based on 50-Ohm ( 100 ohm differential) impedance. All cables, traces must be matched to this characteristic impedance. Any “mis-match” causes reflections, which degrades transmission performance.

Using a HDMI extender to mitigate transmission problems over long cables:

In many front projection installation where cable lengths are significant, the problems described above will surface in the form of “pixelization” or even a complete picture drop out. An external HDMI Extender can be used in order to correct and compensate for the long cables that causes the impairments. The HDMI Extender automatically adjust and compensate for cable attenuation up to 40 dB. In addition, an adaptive equalizer compensates for the time-based skews. A limiting amp “squares ” up and re-shapes the input signal before sending to the output through output buffers.

The HDMI Extender is low power and can be attached to the display end ( after the long cable) to completely rectify any errors caused by transmission over long HDMI cables. The extender is housed in a small ease to use package. Power can be supplied directly from the HDMI source, however an external AC adapter is provided and recommended. The HDMI Extender can be used with DVI-D products simply by using a HDMI to DVI-D cable or adapter.

Conclusion:

HDTV technology is changing rapidly. HD connections such as HDMI will become the de facto standard in HDTV connections. Transmitting HDMI signals over long cables is a challenge and often causes pixelization and signal drop out. An external HDMI Extender can be placed at the display end of the cable to completely compensate for signal degradation caused by a long HDMI cable.

Hewlett Packard’s LaserJet 4200 and the LaserJet 4300 series of printers were first released in November of 2002. They were both designed to replace the now discontinued Hewlett Packard 4100 LaserJet printer.

Based on a new print engine, the 4200 and 4300 series have increased print speeds of 35 ppm (pages per minute) for the 4200 and 45 ppm (pages per minute) for the 4300 with an improved first page out time of less than 9 seconds.

Wow, that is pretty fast. At a starting cost of about $1,000 for the base model 4200 and $1,399 for the base model 4300. These new printers are priced at the same cost as the Hewlett Packard 4100 LaserJet printer.

There are differences in the molding of the cartridges which do prevent them from being interchangeable. One notable difference is in the design of the toner hopper.

The toner hopper on the HP 4300 is larger and holds 1,050 grams of toner for an estimated page yield of. This will approximately perform 18,000 pages @ 5% coverage.

The smaller toner hopper on the HP 4200 holds only 690 grams of toner and yields approximately 12,000 pages @ 5% coverage. Another notable difference is in the waste section. The waste hopper of the HP 4300 is larger to hold the extra waste produced by the higher fill weight.

The HP 4200 waste hopper also has a fin sticking up on the left side of the hopper that prevents the cartridge from fitting into the HP 4300 LaserJet printer.

Due to the fact that the 4200 and the 4300 both use the same print engine, the components that make up the cartridges are the same.

The cartridge chips located on the top right side of the waste hopper however, are in indeed different. A slight difference in programming prevents one chip from being used on both cartridges, so it’s important to use the correct chip when remanufacturing the cartridge.

Though the chip is physically different than that of the HP 4100, the information that the chip contains is nearly the same.

A few additional items like First Installed Date and Last Date Used are one-stored chips. This information is displayed at the bottom of the Supplies Status Page.

Just like the HP 4100, 4200 and the 4300, all can be run with a spent chip or with no chip installed at all.

Several testing have shown that the chip can be run again in the printer that it was used in originally. Running the used chip causes a “Replace Cartridge” message and the loss of the toner low warning.

Usage of the chip in a machine other than the one it was previously running in will result in a “Non-HP Cartridge Detected” message and the loss of all the information on the Supplies Status Page.

While running the cartridge without the chip, it will result in a “10.10.00 Supplies Memory Error” when the cartridge is first installed.

After pressing the Select button a “Non-HP Cartridge Detected message will appear before the machine goes to ready. All the information stored in the chip will not be available and a “Warning” message is all you will find on the Supplies Status Page.

•You will now need to seal the area around the wiper blade using expanding foam along the edge of the blade and in the square holes on the ends.

Step #20:

•Clean the PCR saddles using a swab and alcohol.

Step #21:

•At this point, you want to apply new conductive grease to the black contact saddle. Install the cleaned PCR.

Step #22:

•Apply padding powder to the drum. Slide the drive gear into the bearing hub.

Step #23:

•Install the contact end plate.

Note: Make sure the contact plate sits flush with the end of the waste hopper.

Step #24:

•Install the screw that holds the contact plate in position.

Step #25:

•Place the waste hopper aside in a protected area out of the light.

Step #26:

•Remove the mag roller drive gear housing from the end of the toner hopper. Then remove he mag roller drive.

Step #27:

•Remove the screw that holds the mag roller end plate.

Step #28:

•Using needle nose pliers, simply remove the hinge pin from the mag roller end plate.

Step #29:

•Remove the mag roller tension spring.

Step #30:

•Pull the mag roller end plate from the toner hopper.

Note: Do not lose the bearing that sits inside the mag roller end plate.

Step #31:

•Lift the free end of the mag roller sliding the roller out of the mag roller end plate on the opposite side of the toner hopper.

Note: Do not lose the bearing that sits inside the mag roller end plate.

Step #32:

•Remove the mag roller bearings from the each end of the roller. Clean the mag roller using dry compressed air or vacuum, then using a lint free cloth and a mag roller cleaner. Clean the mag roller bearings and use a lint free cloth.

Step #33:

•Remove the two screws holding the doctor blade.

Step #34:

•Lift the plastic scrapers and mylar shims off each end of the doctor blade.

Step #35:

•Lift the doctor blade from the toner hopper. If you plan on using the doctor blade again, clean the doctor blade using dry compressed air or a vacuum, then using a lint free cloth and alcohol.

Step #36:

•Dump the old toner out of the toner hopper. Using dry compressed air or a vacuum, clean out the hopper.

Step #37:

•Fill the toner hopper with the correct amount of toner depending on the cartridge type you are building.

Step #38:

•Place the new or cleaned doctor blade onto the toner hopper. Place the mylar shims and the plastic scrapers on each end of the doctor blade. Install the two screws holding the blade in place.

Step #39:

•Slide the black mag roller bearing onto the contact end and the white bearing onto the drive gear end of the mag roller. Slide the mag roller contact hub into the mag roller bearing plate on the toner hopper.

Step #40:

•Align the mag roller bearing end plate to the toner hopper and slide the end plate onto the toner hopper.

Step #41:

•Install the mag roller tension spring and the screw into the mag roller bearing end plate.

Step #42:

•Install the hinge pin into the mag roller bearing plate.

Step #43:
•Slide the mag roller drive onto the mag roller.

Note: Make sure the two injection molding points on the mag roller drive gear face outward.

Step #44:

•Place the mag roller drive gear housing onto the end of the mag roller, making sure the keyed end of the magnet fits into the gear housing.

Step #45:

•Using a 3/32-drill bit, drill a hole next to the toner sensing contact on the cartridge contact end cap.

Step #46:

•Join the toner hopper and waste hopper together. Place the cartridge gear housing end cap onto the side of the cartridge. Install the four screws that hold the end cap in place.

Step #47:

•Place the contact end cap onto the end of the cartridge. Install the two screws that hold the end cap in place.

Step #48:

•You will now need to lock the contact end cap in place. To do this, drill a 1/16 hole through the contact end cap and through the toner sensor bar positioning post. The hole needs to be drilled approximately 1/8 from the end of the toner hopper and 1/8 from the end of the sloped section on the contact end cap.

Step #49:

•Now, install a 1/16 spring pin into the hole drilled in the bottom of the contact end cap.

Step #50:

•Install the keyed end of the drum shutter bar into the gear housing end cap.

Step #51:

•Install the non-keyed end of the drum shutter bar into the contact end cap.

Step #52:

•Slide the drum shutter arm onto the positioning post. Push the drum shutter arm into the drum shutter. Gently, slide and open the shutter to engage the tension spring.

Step #53a:

•We are almost done. Place one probe of an Ohmmeter on the toner sensor contact and place the other probe into the hole that was drilled next to the contact. Locate the sensor bar that comes out from the toner hopper through the hole drilled in the end cap, making sure you have a low resistance connection.

Note: If the contact is not made between the sensor bar and the
contact on the end plate, this will result in an error “54.1 Remove Sealing Tape” or if contact is lost during usage, a premature toner low can occur.

Step #53b:

•Test the cartridge.
