Output device
failure
Recommended action:
NOTE: The device is operable under this condition. However, the user might experience a high incidence of
accumulator-eject jams and poor stacking.
1 Analyze the event log for frequency of the error message.
2 Turn the printer or MFP off and then on again to see whether the error is present during the power-on
sequence.
NOTE: The stack-holder contains no FRUs. If the error message appears in a solid condition, then the whole
unit might have to be replaced. Follow your regional escalation process to replace the unit.

Output device
failure
Recommended action:
NOTE: The device is operable under this condition. However, functionality depends on the area of memory that
is damaged.
1 Analyze the event log for the frequency of the error message.
2 Turn the printer or MFP off and then on again to see whether the error is present during the power-on
sequence.
3 Check the Jet Link cable connections.
4 If the message persists, then replace the controller PCA.
External device None
initializing
Recommended action:
This message should appear for a few minutes. If the message persists, then check the following issues:
1 Make sure that the power cord is connected.
2 Check connections at the controller PCA.
3 Replace the Jet-Link cable as needed.
4 Replace the controller PCA as needed.
Optional bin 1 None
full
Recommended action:
1 Remove all media from the face-up bin.
2 If the message persists when the bin is empty, then make sure that the FLFUF actuator (see page 83)
moves freely.
3 Check the functionality of the FLFUF sensor by using the sensor test (see "Face-up bin-full sensor test" on
page 240).
4 If the FLFUF actuator moves freely and the FLFUF sensor operates correctly, but the message persists, then
replace the flipper assembly.

The stack holder system is
damaged
An EEPROM error exists. One
or more cells in the internal
EEPROM on the controller
PCA is damaged.
The device is performing its
power-on sequence along with
the printer or MFP.
The face-up bin is full. More

than 125 sheets of 75-g/m
(20-lb) paper have
accumulated (or fewer than
125 sheets, if heavier media is
in use).
