S600 Part 2: Troubleshooting

3. DISASSEMBLY AND REASSEMBLY

3.1Cautions for Disassembly and Reassembly

3.1.1Cautions for ink stains (Ink path/ink mist)

During servicing, be careful not to touch the ink path and get ink stains on the printer, work table, and your hands and clothing.

The ink path includes the BJ cartridge's ink tank supply inlet, the BJ cartridge's ink filter, the ink nozzles, head cap, wiper, and waste-ink absorber.

Also, a printer that has seen long-time use or heavy-duty use may have ink mist soiling the platen, inside the front cover, and purge section.

3.1.2 Damage by static electricity

The rubbing of clothing can cause a build up of static electricity on the human body. Static electricity can destroy electrical components or alter the electrical characteristics of components.

Be extra careful when handling the control board.

Troubleshooting

3.1.3 Deformation of spur tips

Be careful not to deform the spur tips.

The spur tips contact the paper after the printing. Since the spur tips' contact area is small, any ink adhering to the spur will be a minuscule amount that can be wiped off by the spur cleaner. It therefore will not dirty the paper. However, if the spur's tips are bent of out of shape, the contact area with the paper will be larger, and any ink adhering to the spur will be a larger amount that the spur cleaner might not be able to wipe off completely. The spur will then stain the paper with a dotted line.
