Cleaning of the exterior consists of wiping off dirt and dust on the outer cases using denatured alcohol, as well as vacuuming debris and dust accumulated in the printer. It is important to check that printer gears are adequately lubricated. In addition to maintenance mentioned above, this printer needs an occasional ink pad replacement and printhead cleaning when necessary. This chapter gives information on when and how to maintain the printer. WARNING ;Be sure to unplug the AC power cable before disassembling and assembling the printer. ;Be careful not to get ink in your eyes. If ink does get in your eyes, wash it away with fresh water and see a doctor. ;Follow the instructions below when handling the lithium battery installed on the C202 MAIN board. Keep the battery away from any metal materials. Be sure to mount the battery in the right direction. Do not heat up or burn the battery. ;Once the ink cartridge is removed from the ink cartridge holder for servicing, replace it with a new one before returning to the customer. 6.2 Maintenance 6.2.1 Cleaning To keep this printer working at its best, it is indispensable to keep it clean by removing dust and dirt not only on the outer case but also inside the printer. Accumulated dust and debris may cause a printer malfunction. Therefore be sure to clean the printer interior whenever you get a chance. Read the CAUTION below before performing any cleaning. CAUTION ;Never apply thinner, trichloroethylene, or toner-based solvents to any plastic parts. These substances may cause plastic or rubber parts to deform or degenerate. ;Do not clean cases with a hard brush that may
