NOTE: Once you have set up options for RibbonMinder, it works without
attention. When you begin printing with RibbonMinder enabled, the
message display shows a ribbon life value of 100%. The ribbon life
decreases as the ink is consumed.
RibbonMinder Fault
By pressing the CLEAR key, you clear the fault which will allow the printer to
continue printing for an additional two minutes. This allows you to complete a
nearly finished print job before changing the ribbon.
After the two–minute period has elapsed, the fault will reoccur if the Ribbon
Action remains set on FAULT. If the Ribbon Action is changed to DISABLE or
DISPLAY within the two–minute period, the fault will not reoccur.If you do not
want to change the ribbon at this time, you may disable RibbonMinder. If the
ribbon is worn, the "Change Ribbon" message will reappear once the function is
enabled again, and the printer status indicator will flash until the ribbon is
changed. If a fault message is displayed on the control panel and the ribbon is
changed, the ribbon percentage automatically resets back to 100%.If the
message display indicates the need to install a new ribbon and your print job is
one page short of completion, press CLEAR and then ON LINE to print the last
page. Otherwise, you may continue your print job at the end of this procedure.
The fault will occur again two minutes after clearing the fault.
NOTE: If the fault message appears on the control panel and the ribbon is
changed, the display will automatically reset to 100%.
