Low Performance Mode
Moving to Low Performance Mode
When an error occurs in a location that is neither located in nor affects paper feed in the horizontal feed
path:
• The current settings are written in EEPROM so the horizontal feed path can still operate in lower
performance mode. In low performance mode only the horizontal feed path can be used, but only
for downstream delivery.
• The machine must be cycled off/on to put the bookbinder in the low performance mode.
Low Performance Conditions
Here is a summary of the conditions that put the bookbinder in the low performance mode:
• The error must have no effect on the operation of the horizontal transport path.
• If a jam does occur in the horizontal path, the jam can be easily removed.
• When the error occurred all units where in positions that permit horizontal paper transport.
