Control Panel Messages - HP Color LaserJet 9500 Service Manual

Control panel messages

Be sure to read the exact text of the control panel message, including the error message number
and the text, in order to locate the error message in the tables. The printer and MFP control
panel store enhanced information.
Printer and MFP messages that appear on the control panel provide six categories of
information. Each message category is assigned a priority. If more than one condition occurs at
the same time, the highest priority message appears. When it has been cleared, the next priority
message appears, and so on. The following are the messages and their priorities:
Note Print a configuration page to identify the input or output device that is configured. Notice that the
error format only identifies the Jet-Link device number and the device type. It does not identify the
input or output device.
202 Troubleshooting
Status messages—Status messages communicate the current state of the printer or MFP
to the user. Whenever the device is ready and online, the device status message READY
appears unless warning messages are pending. When the device is performing a task, such
as a reset or a test, the associated device status message appears. When the task is
complete, the message returns to READY, depending on the current state of the printer or
MFP.
Warning messages—Warning messages are messages that are important enough that the
user must acknowledge them, but not serious enough to cause the printer or MFP to stop the
printing process. They are usually transient in nature but they can affect the output, and so a
record of their occurrence is important. Warnings generally alternate with the READY status
message and remain on the control panel until the user touches Continue or presses Stop.
Warnings appear in most recent order (LIFO), with duplicates removed.
Error messages—Error messages communicate to the user that some action must be
performed, such as adding paper or clearing a jam. Some errors are considered auto-
continuable, because the printer or MFP shows the error message appears on the control
panel for 10 seconds, and then the printer or MFP clears the message and continues normal
operation. Pressing a control-panel key during the 10-second period cancels the auto-
continue feature and initiates the function of the key that was pressed. Error messages are
limited to 19 seven-bit characters (or 9 two-byte characters) per line up, and to two lines.
Unlike status and warning messages, error messages stop the printing process. The user
has to either fix the problem or give the device a different command. If the user can continue
past the error conditions without actually fixing the problem, then the user should be able to
perform the task by touching Continue. If only one option is available when the user touches
Continue, printing should continue by applying the option shown. If more than one option is
available, the options are listed with the most logical option listed first and highlighted.
Critical error messages—Critical error messages communicate printer or MFP failures to
the user. Generally, turning power off and then on is required in order for the printer or MFP
to resume normal operation. If the critical error persists, then the printer or MFP probably
requires maintenance and the user will have to request a service call. Critical errors are not
auto-continuable.
Optional paper-handling accessory warning messages—These messages are similar to
the warning messages that are described in the preceding sections, except that they relate
to the output device. By default, the message is all that appears if the output device does not
provide any additional help. The prompt at the bottom of the control panel does not appear.
