Overview
If an ‘843.01 Scanner Service Failure’ error message appears on your printer/MFP, a service call will probably be required, especially if the following caused the issue.
• The ADF form feeder to motor/distribution cable is loose/unplugged. • The plastic sensor flag actuator is broken inside the paper feed assembly.
However, certain rare occurrences, such as a power fluctuation or a static discharge in the vicinity of the printer/MFP, can cause a false ‘843.01 Scanner Service Failure’ error message. In such cases, the error is only temporary and can be easily resolved without service. The following steps will help you determine if a service call will be required.
What You Will See
When you power on the Lexmark 4600 Scanner option connected to Lexmark T64x or a Lexmark C78x Series Printer, you will see an 843.01 Scanner Service Failure on the scanner display.
