10. User correctable Errors User correctable errors are problems that interfere with the print process but do not shut down the printer completely Typically these errors are problems that prevent starting a printing job or that interrupt the current print You should be able to fix user correctable errors without a service call In most cases the printer itself informs you what is wrong by displaying an error message on the control panel Check these common error messages and apply the appropriate remedy System Errors System errors stop the printer and prevent operation until the error is resolved Troubleshooting Example 86 Troubleshooting helps you locate the source of errors and fix common problems that can arise during printing However before you investigate check Is the printer connected to a working power source Troubleshooting Areas m Printer behaviour m Print quality m Data transfer If There is No Power The service should be a dedicated supply that is not susceptible to voltage fluctuations This service must be provided via an independent double pole fused circuit breaker and a circuit ground computer grade located near the machine The service should meet all local and national standards for this type of installation The circuit breaker should be clearly labeled indicating the On and Off positions such as 1 for On and 0 for Off A suitable air gap should be maintained for safe electrical isolation when in t
