EPSON Stylus Pro 3800/3800C/3850 Revision A C A U T IO N „ Ensure sufficient work space for servicing. „ Locate the printer on a stable and flat surface. „ The ink-path-related components or parts should be firmly and securely installed on the printer to prevent ink from leakage. „ Use only recommended tools for disassembly, assembly or adjustment of the printer. „ When using compressed air products; such as air duster, for cleaning during repair and maintenance, the use of such products containing flammable gas is prohibited. „ Apply lubricants and adhesives as specified. „ Be careful not to soil the printer or the floor with the leaked ink when removing the ink-path-related components or parts. Spread a sheet of paper or cloth on the floor in advance. „ Do not touch electrical circuit boards with bare hands as the elements on the board are so sensitive that they can be easily damaged by static electricity. If you have to handle the boards with bare hands, use static electricity discharge equipment such as anti-static wrist straps. „ When reassembling the printer, make sure to connect the connectors of the electric components or parts correctly and securely. Use extreme care when connecting FFCs (flexible flat cables). Improper connection of the FFCs, such as inserting them diagonally into the connectors, could cause shortcircuiting and lead to breakdown of the electric elements on the boards. „ When reassembling the printer, make sure to route the FFCs and other cables as specified in this chapter. (Failure to do so may cause an unexpected contact of the cables with sharp metal edges, or lead to lower the noise immunity.) „ When the printer has to be operated with the covers removed, take extra care not to get your fingers or clothes caught in moving parts. „ When you have to remove any parts or components that are provided as after-service-parts but are not described in this chapter, carefully observe how they are installed and make sure to remember it before removing them. „ When you removed any parts or components that are secured with black acetate tape or two-sided tape, be sure to reinstall and secure them with the tape as exactly the same as they were. C A U T IO N „ Disassembling the frame and some components of the printer is prohibited because they are assembled with precise measurements in 1/100 mm unit at the factory.
