General Procedures/Information
dC123 PEST Fault History
Purpose
To display the Print Engine Self Test (PEST) Fault History. PEST errors identify all faults (cate-
gorized as hard PEST faults) and anomalies (categorized as soft PEST faults).
• Hard PEST faults are defined as faults that stop the machine.
• Soft PEST faults are defined as faults that do not stop the machine. These might be com-
ponents that are operational but not within expected limits. The machine will operate but
the change in the condition of the component might help identify changes or potential
faults in the machine.
• The PEST fault history grows upwards The top entry is the latest entry.
• Each time the machine starts an entry is entered into the PEST fault history.
The entry format is XX-YYY.
– XX is a numerical chain number.
– YYY is a numerical chain link.
• 99-000 is a delimiter that indicates the start of the PEST. If no faults are detected 99-000
is the only entry in the PEST fault history for that start up.
• If there are no faults the next entry will be 99-000 indicating the start of the previous
PEST.
• If faults are detected they are entered in the fault history above the 99-000 for the start of
the PEST.
• Soft faults are listed directly above the 99-000 start of PEST entry.
• Hard faults are listed above the soft faults with a delimiter of 99-999 between the hard and
soft faults.
