F. Advanced Troubleshooting
1. Skewing of the output image is normally a dirty or defective encoder
strip/sensor. Clean encoder strip thoroughly top and bottom using Windex
or NovaKlean solution. Clean encoder sensor by spraying Windex directly
onto sensor; blow dry with canned air – refer to NJ1000i Technical Bulletin
5. Replace encoder strip (service required) if problem cannot be corrected.
2. Missing data in an image is typically a print server or network traffic
problem. Increase data port rate or reconfigure print server.
3. Multiple lines throughout a print typically indicates a problem with the
connectivity to the printer. Ensure only an IEEE compliant parallel printer
cable (if used) and/or switchbox are used. One protruding line or an area
showing over spray is typically a RIP problem and not necessarily a
connectivity issue.
