EPSON Stylus Pro 9000 6.3 Lubrication This printer requires no additional lubrication. Never lubricate the printer mechanism since the lubrication may damage mechanical parts and shorten the product's life. 6.4 Checking and Clearing Counters The printer keeps track of printer component usage by using maintenance counters. When a part exceeds its wear limit, the printer may display a service error code and stop working. See Service Error Codes and Replaceable Parts on page 143. After replacing the part requiring service, you need to reset its maintenance counter. See Clearing Maintenance Counters on page 140. Some parts do not cause the printer to display an error code or stop working when they wear out. However, you should always check the counters for these parts when servicing the printer to make sure they haven't exceeded their useful life. If the counter indicates that a part is about to wear out, you should replace the part to avoid having to make additional service calls. At a minimum, check the following important counters: Table 6-2.
