Note:

Some copiers use ‘E500’ to represent all the above errors.

■Error Condition

qThe copier indicates the “TURN ON POWER” message.

wWhen the power has been turned off and then on, the sorter runs a self check: if the result is good*, it resets; otherwise, enters down state**.

■Down State

qThe copier indicates ‘E5XX’.

wWhen the sorter has been detached, the copier is available for operations other than those that must use the sorter.

eIf a mode that uses the sorter is selected, some copiers indicate the “MODE NOT AVAILABLE” message.
