The hp toner image on the drum surface is not rich and the test sample has a bottom ash. Note that the surface of the drum charge voltage is low or drum wear serious, to clean the charging electrode (charging roller). If it can not always be solved, check the high-voltage circuit, or replace a good high-voltage board to see if the fault disappears. Some models of high-voltage circuits and power control circuit is one, the method can be used to measure the boost components, inspection, repair.

When the above checks are in good condition, check whether the magnetic roller has a bias voltage and the magnetic roller bias is not normal. Adjust the print density knob to observe whether there is any change of the powder carbon image on the photosensitive drum. hp cf230a toner images have changed, indicating that there is a development bias. Powder carbon image no change, may be adjustable potentiometer bad contact or no magnetic roller bias, then you can clean or repair the concentration adjustment potentiometer, you can solve the problem.

If both the charging voltage and the magnetic roller bias are normal, the toner image on the drum surface is light and check if the laser drive current is reduced. Clean the lenses and mirrors in the module first. Because of the contamination of the above components, the penetration and reflectivity of the light beam will be weakened, resulting in underexposure. After cleaning, if the toner image is still light, check whether the contact area of the drum is bad. Because it is not completely dissipated, a small potential difference results in a lack of capacity to attract toner. If the negative electrode contact is good, it may be laser aging or laser beam current is low. Maintenance method is to open the scanning components, the appropriate adjustment of laser beam current. Note that high-speed laser beam current may accelerate the laser aging or damage (except for changes in the laser beam current line component changes), if you are not familiar with this, must not be arbitrary, should be adjusted by an experienced maintenance instructor, Another note, can not be adjusted too large.

After the above check is correct, if the toner image on the drum surface is normal, and the test sample is not enough toner concentration, it is certainly the transfer of low electric field caused. Check the transfer electrode (transfer roller) is dirty or poor contact, and cleaning. If the wire transfer model, should check the location of the electrode wire is correct. If the above parts are normal, then check the transfer voltage generating circuit and check.

HP printers are one of the most popular printer brands in the world along Canon, Panasonic, Xerox, Brother and Epson. Hewlett Packard are also known for their laserjet printers, actually their were the one who introduced the first desktop laser printer to the world in the year 1984 and left an impact to the printing industry, giving a chance to the emergence of new laser-jet printers.

HP toner are known for their durability and efficient functionality that provides printer users with satisfaction. These cartridges contain high-quality toner mixed with polymer that delivers excellent quality of printouts. They also provide you with high-yield and low-yield cartridges. High-yield toner cartridges allow you to print in large volumes but cost more than low-yield cartridges.

Given that HP toners quality and performance are already proven by consumers, some things might intervene the performance of your HP toner cartridges that you need to avoid. Here are some tips to help you use your HP toners to their full potential:

Take Note of Your HP Toner’s Shelf Life - HP toners have an expected life of about 24 months divided between its shelf-life and installed life. The recommended shelf-life of an HP toner cartridge is about 18 months, while the remaining six months is the expected installed life of an HP toner.

Avoid heat, moisture or humidity - Never expose your HP toners to excessive heat or humidity since this could damage their components and render their toner particles unfit for laser printing. Heat can cause toner to prematurely fuse with the plastic while moisture can turn the toner particles soggy and too much exposure on light can damage the photosensitive properties of your HP toners.

Change the Cartridge DrumUnit - If your HP printer contains a separate drum, this drum needs to be replaced time to time. The average install life of an imaging drum last for three toner replacement. Most printer users make the mistake of replacing their toner cartridge instead of changing the printer’s drum unit every time the printer prints sub-par quality documents.

Never Leave them Behind - Never leave newly bought HP toners in your car, as even on cool days the temperature can exceed safe levels which may distort the plastic in the cartridge. The basement isn’t a good place either because it’s damp.

Do Not Touch the Electric Component - Refrain yourself from touching the electric components of your HP toners, doing so may damage it and affect its performance.

Just follow these tips and you’re sure to be getting the best printouts from your HP toners. But most importantly, make sure you purchase your HP toners from reliable online retailers that only provides high-quality HP toners.
