square holes on top of the waste hopper. The
hole must be drilled at an angle so the drill bit
hits the end of the cartridge pin, forcing the pin
outward. (See Photo 4)

a small flat blade screwdriver into the drilled
holes and push the pin out the end of the
cartridge. (See Photo #4b)

In June 2002, HP released the Color
LaserJet 4600 series of printers designed
to replace the outdated HP4500 and
HP4550 series printers. Capable of printing 17 pages per minute in both full color
and monochrome at a resolution of 600
dpi (HP ImageREt 2400) and a first page
out speed of 17.5 seconds, the HP4600
out performs the HP4500 in every way.
At a starting price of $2,600, the
HP4600 is priced $400 less than the
starting price of the HP4500 when it was
released back in October 1998.
In order to reach the print performance
found using the HP4600, Hewlett
Packard used technology that we have
not seen from them.
A completely new development system
using contact type developer rollers and
toner charge rollers is found in the 4600
cartridges. This development system
resembles more the non-magnetic
contact systems found in Lexmark toner
cartridges than the classic Canon/HP
jumping development used in all of their
previous printer models.
Four-color registration is done directly
on the print media eliminating the
intermediate transfer belt found in earlier
color printers. In preparation for toner
transfer, the paper is attached to an
electrostatic transport belt (ETB) that
controls the paper movement sufficiently
to allow for “direct to paper” 4-color
registration.
For lower power consumption and
faster heat-up times, Canon/Hp has
introduced an induction coil type fuser
assembly in this printer.
The toner cartridges are hinged so that
a cam mechanism in the printer can
disengage the developer rollers from
the OPC drums. This allows for a
monochrome-printing mode where only
the black cartridge developer roller is
engaged. All four developers are disengaged during ETB cleaning as well as
primary and toner charge roller cleaning
operations. The printer automatically
initiates cleaning operations at intervals
of 51, 90 and 140 pages (after the print
job is completed).
The HP4600 uses two active calibration sensors that (left and right) read
reflected light from density patches
developed directly on the ETB for adjusting print density and halftone quality.
Calibration routines occur at various
automatic intervals. The HP4500 printer
used only one calibration sensor.
A wireless rfid type memory chip, like
the chips on the HP4100 are found on
the waste hopper of each toner cartridge.
The chips store color type and manufacturing information as well as job, page
and other counts. The printer tracks
separately both drum and developer
roller rotations, storing these counts in
the cartridge memory chips.
These counts are tracked separately
because all of the OPC drums rotate
whenever the ETB is moving but the
developer rollers may not be turning if
they are disengaged. Depending on
printing mode these counts can deviate
significantly.
Even the toner sensing mechanism in
the HP4600 is much more complex.
The percentage toner remaining
displayed on the Supplies Status Page
for each cartridge comes from four
possible sources (without any indication
to the user of which).
For the first 75% of a toner cartridges
life the value is based on pixel counting.
When the level remaining reaches 25%
the printer switches the source to the
optical sensing system. Light is detected
after passing through each toner hopper.
The two other sources of the percent
life remaining value are the OPC drum
and developer roller cycle counts
stored in the cartridge memory chips.
A cartridge may be removed from service
before the useful amount of toner is
consumed because either the drum or
developer count exceeds preset values.
This is explained in the HP Service
Manual to prevent waste section
overflow (drum count) or print quality
problems due to degradation of the toner
itself or developer roller wear (developer
count).
The HP4600 also uses a new all-in-one
cartridge design. The cartridges are identical so the remanufacturing process is
the same for all four cartridges, the only
difference being the black cartridge
yields 1,000 pages more than the color
cartridges.
The black cartridge (C9720A) prints
9,000 pages at 5% coverage while the
color cartridges cyan (C9721A), magenta
(C9723A), and yellow (C9722A) print
8,000 pages at 5% coverage.
