HP launches network color laser printer for workgroups

The Color LaserJet CP4025n prints up to 35 color and monochrome pages per minute. The loading capacity can be expanded from 600 to 1100 sheets. The price is 1,000 euros.

Hewlett-Packard has a network ready color laser printer for workgroups with up to 15 people present, the energy saving is to work due to instant-on technology. The Color LaserJet CP4025n driving without a long warm-up immediately high when a print job is present. The recommended monthly print volume is 2000 to 7500 sheets, maximum 100,000 pages per month are possible.

The print resolution is 1200 by 1200 dpi. The CP4025n prints according to the manufacturer up to 35 A4 pages per minute in color and black and white. The first printed page is to be completed in under 9.5 seconds.

The color laser printer is processing A6 to A4 and custom sizes and weights up to 220 grams per square meter. The standard paper tray holds 500 sheets and can optionally be expanded to a 500-sheet feeder with cabinet or shelter. In the multi-purpose tray 100 sheets fit again. The model also offers a variant CP4025dn integrated duplex unit for double-sided printing.

It is operated by a four-color displays. USB 2.0 or Gigabit Ethernet interface can be compatible with the Windows, Mac OS and Linux printers incorporate into the network.

The Color LaserJet CP4025n is expected to be available in March. The suggested retail price for the standard version is 999 euros. The duplex CP4025dn version costs 1299 euros.

Why can't the battery be charged? How to solve this problem?

1)Reason:
a.The battery has no voltage.
b.There is problem with charger, as it has no output electric current.
c.Low charging efficiency due to external cause.
2)Solutions:
a.Test whether the charger has voltage and output electric current or not.
b.Check if the charger is well contacted with battery.
c.Activate the battery with voltage and current 1.5 time higher then the highest ones of battery. (Use this method only when the battery can't be charged.)

What causes short lifetime of battery? How to prolong the lifetime of battery?

1)Reason:
a.Charger or electro circuit can't be fit for the battery.
b.Overcharge and overdischarge, etc.
c.Battery can't comply with the charging requirement
2)Solution:
a.Use the original charger.
b.Charge the battery after it automatically powers off , then full charge the battery.
c.Avoid erroneous usage of battery, such as heavy pressure, short circuit, fall off and so on.

What are the differences between Primary Battery and rechargeable battery?

A primary battery is not intended to be recharged and is discarded when the battery has delivered all of its electrical energy.
A rechargeable battery is a galvanic battery which, after discharge, is restored to the fully charged state by the passage of an electrical current through the cell in the opposite direction to that of discharge.

How to classify the battery?

Batteries are grouped into following categories:
Alkaline battery
Zincic carbolic battery
Lead-Acid battery
nickel-metal-hydride
nickel-cadmium
Lithium battery
Li-ion battery
Li-polymer battery
Fuel cells
Solar cells
Other types of battery

What is a Battery?

In science and technology, a battery is a device that stores energy and makes it available in an electrical form. It converts chemical energy into electrical energy, producing an electric current when connected in a circuit. The finished battery is an electrically connected group of cells (wired in series) that stores an electrical charge and supplies a direct current (DC). We usually call finished battery as battery pack and unfinished battery is called as cell.
