About the PrinterReleased in October 1998, the Hewlett-Packard® Color LaserJet® 8500 was positionedas a high-performance, high-volume printertargeted at the corporate department. The8500 offered a number of additional featuresnot found on the HP4500, which was releasedthe same month. Additional features includedfaster print speeds, a hard disk drive support,11" x 17" paper size capability, and more

robust paper input and output capabilities. Atthe time of its introduction, the Canon® enginein the 8500 was one of the fastest on the mar-ket with a color print speed of 6 ppm and amonochrome speed of 24 ppm.

In April 2000, Hewlett-Packard introduced the8550 as an upgrade model featuring a fasterprocessor and a suggested list price reductionof approximately $2000. The 8550 product lineis comprised of the base-level 8550 model, twoenhanced versions, the 8550 DN and GN, andan 8550 MFD version featuring a scanner toprovide digital copier functionality.

The 8500 and 8550 feature chemically-manu-factured color toners, an oil-less fuser design,and a rotating carousel color cartridge mecha-nism. Both the 8500/8550 use a conventionally-manufactured magnetic, monocomponentblack toner. Although very similar in manyways to the HP4500, the 8500 and 8550 use atransfer drum rather than an intermediatetransfer belt. The supplies set for the HP8500and 8550 consists of seven consumables: fourtoner cartridges, an image drum, a transferdrum, and a fuser assembly.

Use of Compressed AirAs of April 28, 1971, the Occupational Safety & HealthAdministration (OSHA) Standard, 29 CFR 1910.242 paragraphsa & b for general industry requires effective chip guarding andpersonal protective equipment (PPE) when using compressedair. When cleaning residual toner particles from cartridgesusing a compressed air system, you must use air nozzles meet-ing OSHA requirements. Air nozzles that regulate air pressureto a maximum of 30 psi comply with this standard. Refer to theOSHA publication for any updates or changes that haveoccurred since the date noted above.

Use of Isopropyl AlcoholFor best results, we recommend using ONLY 91-99% isopropylalcohol for cleaning as directed in these instructions. 91%Isopropyl alcohol is available at most major drug stores; 99%Isopropyl alcohol is available through distributors of chemicalproducts. Follow the alcohol manufacturer's safety instructions.
