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) Photo 4b NOTE: If the pins are not pushed out, insert a small flat blade screwdriver into the drilled holes and push the pin out the end of the cartridge. (See Photo #4b) Photo 5 Photo 6 Step 4 Flip the cartridge over so the toner hopper is facing up. Using diagonal cutters, remove the cartridge pins from each end of the cartridge. (See Photos 5 & 6) Notes Photo 7 Step 5 Using a spring hook, release the tension spring that holds the waste hopper to the toner hopper on the contact side of the cartridge.

Photo 43 Install the drive gear end of the developer roller axle into a drill and tighten the chuck. Clean the developer roller using a lint-free cloth and 99% Alcohol while the roller is rotating in the drill. Once the roller is clean, go over the roller again using distilled water and a lint-free cloth. Make several passes. Dry the roller using a dry lint-free cloth. (See Photo 46) NOTE: The surface of the developer roller may change and become wrinkled. If properly cleaned, the developer roller will go back to its original state when finished with the cleaning process. Photo 47 Step 43 Remove the two screws holding the doctor bar. (See Photo 47) Step 40 Photo 48 Carefully lift out the developer roller. (See Photo 44) Photo 44 Photo 49 NOTE: On some of the old HP4600 cartridges the doctor blades are adhered to the developer roller end felts. If so, insert an angled knife behind the ends of the doctor blade and carefully cut the doctor blade free. (See Photo 48) Step 44 Remove the doctor blade from the toner hopper. (See Photo 49) Clean the doctor blade using dry compressed air.

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.
