Step 33Install the drive gear end on the developerroller axle into a drill motor and tighten in thechuck. Clean the developer roller using a lint-free cloth and 99% alcohol while the roller isrotating in the drill. (See Photo 33) Once theroller is clean, go over the roller again usingdistilled water and a soft lint-free cloth. Makeseveral passes. Dry the roller using a dry, softlint-free cloth.NOTE: The surface of the developer roller maychange and become wrinkled. If properlycleaned, the developer roller will go back to itsoriginal state when finished with the cleaningprocess.

Step 34Remove the two Phillips screwsholding the doctor blade to thetoner hopper. Clean the doctorblade using dry compressed air.(See Photo 34)
Step 35Clean gears using dry compressedair and dry, soft lint-free cloth.
Step 36The next steps will fill the toner car-tridge with the supply roller in placeusing the Mag Funnel. Place tonercartridge into holding device or fix-ture. Place the Mag Funnel in theopening for the developer roller.Holding the Mag Funnel in onehand, pour the toner with the otherhand. (See Photo 35)NOTE: Look inside of toner car-tridge to ensure the agitator bladeis not blocking opening. Move theagitator drive gear to move theblade into the correct position.

In January of 2004, HP released two color laser printers intothe North American market. The HP Color LaserJet 3500 and3700 are based on a new Canon engine similar to that of the HP4600. The single pass engine design enables the new printersto deliver 12ppm and 16ppm while printing either monochromeor color.
While both machines use the same black cartridge, the colorcartridges are different. The black cartridge, Q2670A, yields6,000 pages at 5 % coverage. The color cartridges for theHP3500, Q2671A (cyan), Q2672A (yellow), Q2673A (magenta),yield 4,000 pages at 5 % coverage. The HP3700 color car-tridges, Q2681A (cyan), Q2682A (yellow), Q2683A (magenta),yield 6,000 pages at 5 % coverage. All the internal componentsare the same for all the cartridges the only difference is the chipand the cartridge fill weights.
