General Troubleshooting
Introduction
This chapter covers the System Startup, Power On Self Test (POST), Service
Diagnostics, and troubleshooting procedures not associated with an error code or
Control Panel error message. For troubleshooting problems associated with a error
message, refer to “Error Messages and Codes” on page 3-1. Print-quality problems
are covered in “Print-Quality Troubleshooting” on page 5-1.
Initial Actions
Some problems are easy to resolve. Use these steps in an attempt to quickly
isolate the problem.
1. Turn Off the printer, wait 10 seconds, then turn On the printer. This often
solves problems related to power transients, ESD, and software errors.
2. If a message appears on the Control Panel, see “Error Message and Code
Summary” on page 3-6 for specific procedures related to error messages.
3. Check the power cord. Is the power cord plugged into the printer and a
properly grounded electrical outlet? Is the power cord damaged?
4. Check the electrical outlet. Is the outlet turned off by a switch or breaker?
5. Does other electrical equipment plugged into the outlet operate?
6. Are all options properly installed?
Display Problems
If the Control Panel displays only diamonds or is blank:
1. Turn Off the printer, wait 10 seconds, then turn On the printer.
2. Self Test Messages should appear on the display. If not, see “Control Panel
Troubleshooting” on page 4-66.
3. When tests complete, “Ready to Print” should appear on the display.
If the problem persists see “Control Panel Troubleshooting” on page 4-66, and “DC
Power Supply Troubleshooting” on page 4-68.
Printing Problems
If menu settings entered from the Control Panel have no effect, change or disable
print settings from the print driver, the print utilities, or the application.
Note
Settings made in the application, print driver, or print utilities override settings
made from the Control Panel.
If a job did not print correct or incorrect characters were printed, check the
following:
1. Check for “Ready” on the display before sending a print job.
2. Check the loaded media.
3. Check the print driver.
4. Check the printer connections to Ethernet or USB.
