Hard Down Faults
Hard Down faults prevent a subsystem, module or component from functioning properly. There are
three categories of Hard Down faults.
• Low Level Fault this occurs when a subsystem or module is unable to function correctly. For
example, if during a stapler job a fault is detected, other features are still functional but the stapler
is unavailable.
• Failure Fault this is declared when a low level fault causes a major subsystem to function
incorrectly. For example if a fault occurs with the Xerographic Module causing the print and copy
features to become non-functioning.
• Fatal Fault this occurs when a system wide failure exists that is unrecoverable. For example a
power fault occurs causing the device to be inoperable.
Customer Clearable Faults
A Customer Clearable fault is a fault that can be cleared by the user. There are three categories of
Customer Clearable faults:
• Low Level Fault this occurs when a subsystem has detected a customer clearable fault, for
example, when a stapler runs out of staples. The print and copy features are still operable, but the
stapler function is not.
• Failure Fault this is declared when a Low Level Fault causes a major subsystem to become
unavailable. For example, when a paper misfeed is detected, the print and copy functions are
made inoperable until the paper is cleared by the user.
• Reset Fault this can be cleared by powering the device off then on again.
Status Messages
Status Messages are informal messages that do not impact the device from functioning properly.
There are two categories of Status Messages:
• Warning Messages are informational and usually have to do with replacing consumables. The
messages warn the local user of impending problems, or actions, that need to be taken to avoid a
fault occurring. For example, if the Xerographic Module is close to the end of its life, the device
displays a warning message that the unit needs to be replaced soon. At this time the system sets a
pre-defined limit until a Customer Clearable fault is declared to change the Xerographic Module.
• Job Fault Messages indicate a fault with the job, for example the required paper is unavailable. If
a job is paused because of a fault, the user is required to take action to correct the condition, or to
delete the job.
