First introduced in April 2008, the HP LaserJet P4014 engine is a 45-62 ppm (depending on the model), 1200 dpi engine. These
printers will most likely replace the 4200/4300 series.

All of the machines in all three series have a first page out in less than 8.5 seconds, come with 128Mb of ram (Expandable to
640Mb),and have a 400MHz processor. All also come standard with a 10,000 page low yield cartridge. The new CC364A and
CC364X cartridges are rated for 10,000 and 24,000 pages respectively. The HY cartridges will not physically fit into the P4014
machines, only in the P4015 and P4515 series.

The following figures show the difference between the two cartridges:

The toner used in these cartridges is also new. HP says it uses their “Enhanced Low-Melt Toner technology”. This toner according
to HP uses 15% less energy to fuse to the paper. In the fine print of the toner fact sheet they clarify that to mean 15% less as
compared to its predecessor. What exactly is the predecessor? They don’t say. Regardless, our testing has shown it to be a low
melt toner.

The current machines that use these new cartridges are as follows:

Printer usage, as well as some common printer/cartridge problems will be covered at the end of this article.

As these machines use new technology such as dual laser beams, we will run through the theory and explain how the new tech­nology works.

This illustration gives a nice view of the cartridge as it relates to the printer.

The image formation process consists of 8 steps which are split up into five functional blocks.

In the first step, the Primary Charge roller (PCR) places a uniform negative DC Bias voltage on the OPC drum surface. The amount
of the negative DC Bias placed on the drum is controlled by the printer’s intensity setting. This process is part of the latent Image
formation block.

In the second step, (also part of the latent Image formation
block), the laser beam is fired onto a rotating mirror (called the
scanner). As the mirror rotates, the beam reflects into a set of
focusing lens. The beam then strikes the OPC’s surface, which
neutralizes the negative charge on the drum and leaves a
latent electrostatic image on the drum. The laser unit actually
fires 2 beams. The service manual talks about the second
bean being used to erase residual charges, but not if it also
helps to write the image.

The third step (developing block) is where the toner image is developed on the drum by the developing section, (or supply cham­ber), which contains the toner particles. The toner is held to the magnetic roller sleeve by the stationary magnet inside the sleeve,
and a DC bias voltage supplied by the high voltage power supply. This DC bias voltage is controlled by the printer’s density set­ting, and causes either more or less toner to be attracted to the drum. This in turn will either increase or decrease the print den­sity. Both the Primary Charge roller and magnetic roller DC Bias voltages are controlled by the printer’s density setting. The
amount of toner on the magnetic roller sleeve is also controlled by the rubber Doctor blade, which uses pressure to keep the
amount of toner on the magnetic roller sleeve constant. This blade also causes a static charge to build up on the toner, which
helps keep the coating of toner even, and allows easy transfer to the OPC drum.

At the same time an AC signal is also placed on the magnetic roller sleeve. This signal decreases the attraction of the toner to
the Magnetic Roller sleeve, and increases the repelling action of toner against the areas of the drum that was not exposed to the
laser beam. This AC potential improves the density, and contrast of the toner on the printed page.

As the laser exposed areas of the OPC drum approach the magnetic roller, the toner particles are attracted to the drums surface
due to the opposite voltage potentials of the toner, and laser exposed surface of the OPC drum.

In the fourth step (transfer block) the toner image is then
transferred to the paper as it passes below the drum by the
transfer charge roller, which places a positive charge on the
back of the paper. This positive charge causes the negatively
charged toner on the drum’s surface to be attracted to the
page. The small diameter of the drum, combined with the stiff­ness of the paper causes the paper to peel away from the
drum.

In the fifth step (also part of the transfer block) the paper sep­arates from the drum. The static charge eliminator weakens
the attractive forces between the negatively charged drum sur­face, and the positively charged paper. This prevents toner
dropouts onto the paper at low temperatures and humidity
and also prevents paper from wrapping around the drum.

In the sixth step (fusing block) the image is then fused on to the paper by the fuser assembly, which is comprised of the upper
fixing film assembly and the lower fuser roller. The paper passes between a heated upper fixing film assembly and a soft lower
rubber roller. The upper heated element then melts the toner into the paper. The fixing film assembly consists of a Teflon sleeve
with a ceramic heating element inside. These fusers are a bit different in that they have a Brush which has a DC Bias charge on
it to help keep the film clean.

In the seventh step (Drum cleaning block) the OPC drum is
cleaned. On average, approximately 95% of the toner is trans­ferred to the paper during the print cycle. As the drum rotates
during printing, the remaining 5% of the toner that is on the
OPC drum is cleaned off the drum by the wiper blade. It is then
guided into the waste chamber by the recovery blade, and
stored in the waste chamber.

Step 8 is where the residual charge is eliminated. Here is
where there is a major difference from previous HP car­tridges/printers. In all previous PCR based cartridges, the
Primary Charge Roller places an AC voltage across the drum
surface that erases any residual charges left on the drum sur­face.

These machines use the new second laser beam to eliminate
the residual charges. This drum charge elimination is only
turned on during the last rotation period of the drum.

With the higher speeds of these new machines, my guess is
that using the PCR to erase the residual charges was not effi­cient at these speeds... This new laser process is.
