Phaser 6280 Color Laser Printer Service Manual iii Service Terms Manual Terms Various terms are used throughout this manual to either provide additional information on a specific topic or to warn of possible danger present during a procedure or action. Be aware of all symbols and terms when they are used, and always read Note, Caution, and Warning statements. Note A note indicates an operating or maintenance procedure, practice or condition that is necessary to efficiently accomplish a task. A note can provide additional information related to a specific subject or add a comment on the results achieved through a previous action. Caution A caution indicates an operating or maintenance procedure, practice or condition that, if not strictly observed, results in damage to, or destruction of, equipment. Warning A warning indicates an operating or maintenance procedure, practice or condition that, if not strictly observed, results in injury or loss of life. Product Terms Caution: A personal injury hazard exists that may not be apparent. For example, a panel may cover the hazardous area. Danger: A personal injury hazard exists in the area where you see the sign.

iv Phaser 6280 Color Laser Printer Service Manual Symbols Marked on the Product Danger invisible laser radiation when open. Avoid direct exposure to beam. Hot surface on or in the printer. Use caution to avoid personal injury. Use caution (or draws attention to a particular component). Refer to the manual(s) for information. It may take 30 minutes for the fuser to cool down. Do not touch the item. Do not expose the item to sunlight. Do not expose the item to light. Do not burn the Print Cartridge. Do not expose the Print Cartridge to sunlight. Recycle the item.

Phaser 6280 Color Laser Printer Service Manual v Power Safety Precautions Power Source For 115 VAC printers, do not apply more than 127 volts RMS between the supply conductors or between either supply conductor and ground. For 230 VAC printers, do not apply more than 254 volts RMS between the supply conductors or between either supply conductor and ground. Use only the specified power cord and connector. This manual assumes that the reader is a qualified service technician. Plug the three-wire power cord (with grounding prong) into a grounded AC outlet only. If necessary, contact a licensed electrician to install a properly grounded outlet. If the product loses its ground connection, contact with conductive parts may cause an electrical shock. A protective ground connection by way of the grounding conductor in the power cord is essential for safe operation. Disconnecting Power Warning Turning the power Off using the power switch does not completely de- energize the printer. You must also disconnect the power cord from the printer’s Alternating Current (AC) inlet. Disconnect the power cord by pulling the plug, not the cord. Disconnect the power cord in the following cases: ■ if the power cord or plug is frayed or otherwise damaged, ■ if any liquid or foreign material is spilled into the product, ■ if the printer is exposed to any excess moisture, ■ if the printer is dropped or damaged, ■ if you suspect that the product needs servicing or repair, ■ whenever you clean the product.

vi Phaser 6280 Color Laser Printer Service Manual Electrostatic Discharge Precautions Some semiconductor components, and the respective sub-assemblies that contain them, are vulnerable to damage by Electrostatic Discharge (ESD). These components include Integrated Circuits (ICs), Large-Scale Integrated circuits (LSIs), field-effect transistors, and other semiconductor chip components. The following techniques will reduce the occurrence of component damage caused by static electricity. Be sure the power is Off to the chassis or circuit board, and observe all other safety precautions. ■ Immediately before handling any semiconductor components assemblies, drain the electrostatic charge from your body. This can be accomplished by touching an earth ground source or by wearing a wrist strap device connected to an earth ground source. Wearing a wrist strap will also prevent accumulation of additional bodily static charges. Be sure to remove the wrist strap before applying power to the unit under test to avoid potential shock. ■ After removing a static sensitive assembly from its anti-static bag, place it on a grounded conductive surface. If the anti-static bag is conductive, you may ground the bag and use it as a conductive surface. ■ Do not use freon-propelled chemicals. These can generate electrical charges sufficient to damage some devices. ■ Do not remove a replacement component or electrical sub-assembly from its protective package until you are ready to install it. ■ Immediately before removing the protective material from the leads of a replacement device, touch the protective material to the chassis or circuit assembly into which the device will be installed. ■ Minimize body motions when handling unpacked replacement devices. Motion such as your clothes brushing together, or lifting a foot from a carpeted floor can generate enough static electricity to damage an electro-statically sensitive device. ■ Handle IC’s and Erasable Programmable Read-Only Memories (EPROM’s) carefully to avoid bending pins. ■ Pay attention to the direction of parts when mounting or inserting them on Printed Circuit Boards (PCB’s).

Phaser 6280 Color Laser Printer Service Manual vii Service Safety Summary General Guidelines For qualified service personnel only: Refer also to the preceding “Power Safety Precautions” on page v. Avoid servicing alone: Do not perform internal service or adjustment of this product unless another person capable of rendering first aid or resuscitation is present. Use care when servicing with power: Dangerous voltages may exist at several points in this product. To avoid personal injury, do not touch exposed connections and components while power is On. Disconnect power before removing the power supply shield or replacing components. Do not wear jewelry: Remove jewelry prior to servicing. Rings, necklaces, and other metallic objects could come into contact with dangerous voltages and currents. Warning Labels Read and obey all posted warning labels. Throughout the printer, warning labels are displayed on potentially dangerous components. As you service the printer, check to make certain that all warning labels remain in place. Safety Interlocks Make sure all covers are in place and all Interlock Switches are functioning correctly after you have completed a printer service call. If you bypass an Interlock Switch during a service call, use extreme caution when working on or around the printer. Class 1 Laser Product The Phaser 6280 is certified to comply with Laser Product Performance Standards set by the U.S. Department of Health and Human Services as a Class 1 Laser Product. This means that this product does not emit hazardous laser radiation; which is possible only because the laser beam is totally enclosed during all modes of customer operation. When servicing the printer or laser unit, follow the procedures specified in this manual and there will be no hazards from the laser.

viii Phaser 6280 Color Laser Printer Service Manual Servicing Electrical Components Before starting any service procedure, switch the printer power Off and unplug the power cord from the wall outlet. If you must service the printer with power applied, be aware of the potential for electrical shock. Warning Do not touch any electrical component unless you are instructed to do so by a service procedure. Servicing Mechanical Components When servicing mechanical components within the printer, manually rotate the Drive Assemblies, Rollers, and Gears. Warning Do not try to manually rotate or manually stop the drive assemblies while any printer motor is running. Servicing Fuser Components Warning This printer uses heat to fuse the toner image to paper. The Fuser is VERY HOT. Turn the printer power Off and wait at least 5 minutes for the Fuser to cool before attempting to service the Fuser or adjacent components.
