Hewlett-Packard® 4600Remanufacturing Instructions

Reference InfoInitial Report from Static's LaboratoriesThe following report contains preliminaryinformation on the Hewlett Packard®

LaserJet® 4600 series color laser printers andcartridge.

The new HP color LaserJet® 4600 seriesprinters replace the two-year-old HP4550,4550n, 4550dn and 4550hdn machines. With afirst page out time of 18 seconds and printspeeds of up to 17 ppm in both monochromeand color modes, and print resolutions of 600dpi (HP ImageREt 2400), the 4600 offers high-performance andquality printing for under $2,000 (base model).

There are four models in the 4600 series; thebase 4600, the 4600dn (duplexstandard/network-ready), 4600dtn (duplexstandard/network-ready), 4600hdn(duplex & hard drive standard/network-ready).

Faster, more efficient printingThe 4600 series utilizes an instant-on fuser,providing faster first page out time,and HP's vertical in-line, direct-to-paperprinting technology rather than four-passprinting. Toner is transfered directly from thefour print cartridges to the paper,making printing more efficient and consistent.Though four-pass printing takes lessspace and is less expensive, the main benefit ofin-line printing to high-volume customers isfaster color speed.

New cartridgesAll four models ship with an embedded web

server for printer and suppliesmanagement, one 9,000-page black tonercartridge and three 8,000-page colorcartridges.

Static Control's Imaging Labs are in theprocess of testing the HP4600 cartridges andwill provide the results as they becomeavailable. For more information, visit www.scc-inc.com/Engine.

Use of Compressed AirAs of April 28, 1971, the Occupational Safety &Health Administration (OSHA) Standard, 29CFR 1910.242 paragraphs a & b for generalindustry requires effective chip guarding andpersonal protective equipment (PPE) whenusing compressed air. When cleaning residualtoner particles from cartridges using acompressed air system, you must use airnozzles meeting OSHA requirements. Airnozzles that regulate air pressure to amaximum of 30 psi comply with this standard.Refer to the OSHA publication for any updatesor changes that have occurred since the datenoted above.

Use of Isopropyl AlcoholFor best results, we recommend using ONLY91-99% for cleaning as directed in theseinstructions. 91% isopropyl alcohol is availableat most major drug stores; 99% isopropylalcohol is available through distributors ofchemical products. Follow the alcoholmanufacturer's safety instructions.

Printer Preparation1. Using the printer's keypad, place the printer in the Disable Cartridge Check diagnostic mode*.

Cartridge Preparation2. Chip: The cartridge can be post tested with no chip, a used chip, a spent chip, or a new chip (no information will be written to the

chip).Toner: Measure 1 gram of toner onto a small piece of paper (approx. 4" x 4") Uniformly distribute the toner into the valley where the developer roller contacts the developer roller sealingblade, along the entire length of the roller. Rotate the developer roller by rotating the uppermost gear in the gear train, movingthe top of the gear towards the rear of the hopper. The rotation of the developer roller will draw the toner into the seal area anddistribute it evenly across the surfaces of the developer roller and adder roller. Continue rotating the roller until all of the tonerhas been drawn into the seal area.Cartridge: Assemble the waste bin section to the hopper.

Printing 3. Instruct the printer to print two 30% pages followed by 10 solid pages.

*To enter Disable Cartridge Check diagnostic mode:1) Printer must be in 'Ready' state with all installed cartridges having a chip installed2) Press ' ' Select Button to access menus3) Press ' ' Down Button 3 times to 'Diagnostics'4) Press ' ' Select Button to enter Diagnostics menu5) Press ' ' Down Button 3 times to 'Disable Cartridge Check' 6) Press ' ' Select Button to enter Disable Cartridge Check mode7) Display will read 'Ready Diagnostic Mode'

SSS™.492 page 27


Important: Do not use 91% isopropyl alcohol to clean these component parts. Using 91% isopropyl alcohol will require excessivescrubbing, which will damage the Doctor Blade and Developer Roller.

Doctor Blade Cleaning1. Using dry, filtered, compressed air clean any loose toner from the Doctor Blade.

2. Use a dry lint free cloth to remove any remaining toner from the coated surface of the working edge (the surface which contactsthe Developer Roller).

3. Then, use 99% isopropyl alcohol and a cotton swap to remove any toner build up left on the surface of the Doctor Blade.

Note: After removing the toner build-up, the working edge of the Doctor Blade will remain discolored from the toner. Do notattempt to remove this discoloration or you could damage the Doctor Blade.

4. If necessary repeat step 3 and apply isopropyl alcohol directly to the Doctor Blade. Then inspect the surface to ensure that it iscompletely clean and free of any toner build up.

Note: If the toner build-up is not thoroughly cleaned you will see a print defect consisting of vertical streaks on solid color testpages.

5. Once you are sure that the Doctor Blade is clean, use a lint free cloth dampened with deionized water to wipe down the entiresurface of the Doctor Blade. The lint free cloth should only be damp, not completely wet. Using excessive amounts of deionizedwater will result in a longerdrying time.

Note: Before installing the Doctor Blade in to the cartridge it must be completely dry. Usually a drying time of 5 minutes is enough,but if a large amount of deionized water was used, the drying time will be increased. If after 5 minutes there are still visible signs ofdeionized water on the Doctor Blade, use dry, filtered, compressed air to dry it completely.
