General Troubleshooting

Introduction

Hidden Service Menu

4-2
This chapter covers the general start-up, Power On Self Test (POST), and
power supply operations of the printer to aid in troubleshooting problems not
associated with a Control Panel error message or error code. For
troubleshooting problems associated with an error code or Control Panel error
message, notes on how to use the troubleshooting procedure tables, and how
to use service diagnostics, see Chapter 3 "Error Messages and Codes" on
page 3-1. The Printer Status page also contains useful troubleshooting
information. This page provides general printer information, life information for
all consumables, printhead cleaning and power cycles, and jam and error
code information.
Troubleshooting procedures will isolate a problem to a specific component or
subassembly, in some cases including the wiring harness. If you go through
the procedures in a troubleshooting table and still are unable to solve the
problem, re-read the Theory of Operations for the problem area and ensure
that you understand how that section of the printer is supposed to function.
The Hidden Service Menu provides access to a large group of information
pages and functions usable for diagnosing and correcting printer malfunctions
and accessing special features. Display the Hidden Service Menu as follows:
1. On the Control Panel, press the Down Arrow button to select
Troubleshooting and then press OK.
2. Press the Down Arrow button to select
OK.
3. While pressing and holding down the Up Arrow button, press the Down
Arrow button to display the Hidden Service Menu.
