Status Indicator RAPs
09-900 Imaging Unit Undetected Fault
The Imaging Unit has not been installed or machine software is unable to detect the Imaging
Unit.
BSD-Reference: 9.1 Xerographics
Initial Actions
• Ensure that a genuine Xerox Imaging Unit has been installed.
• Switch Off the power then switch On the power.
Procedure
WARNING
Do not perform repair activities with the power on or electrical power supplied to the
machine. The machine could activate and cause serious personal injury when the power
is on or electrical power is supplied.
DANGER: Ne pas effectuer de dépannage avec le contact principal activé ou avec l'ali-
mentation électrique appliquée à la machine: celle-ci pourrait démarrer et causer de
graves blessures.
AVVERTENZA: Non effettuare alcuna riparazione con la macchina accesa o con l'ali-
mentazione elettrica inserita. La macchina potrebbe avviarsi all'improvviso e causare
gravi ferite.
VORSICHT: Es dürfen keine Reparaturarbeiten durchgeführt werden, solange das Gerät
eingeschalten oder mit der Stromquelle verbunden ist. Das Gerät kann u.U in den Aktiv-
Zustand übergehen und somit erhebliche körperliche Schäden verursachen.
AVISO: No realice reparaciones con la máquina encendida o conectada a la corriente. La
máquina podría activarse y ocasionar daños personales graves.
1. Switch Off the power.
2. Remove the Imaging Unit.
3. Check the CRUM contact area for contamination and clean if necessary.
4. Reinstall the Imaging Unit
5. Check the contacts on the HVPS.
6. If the problem continues, install a new Imaging Unit.
10-100 Fuser Temperature (Open) Fault
The temperature of the Fuser is outside of the normal operating range of 383°F ± 5°F (195°C ±
5°C.)
BSD-Reference: 10.1 Fuser
Initial Actions
Switch Off the power then switch On the power.
Procedure
WARNING
Do not handle the fuser components until they have cooled. Some fuser components
operate at hot temperatures and can produce serious personal injury if touched.
DANGER: Ne pas manipuler les éléments du four avant de les laisser refroidir. Certains
éléments du four fonctionnent à des températures très élevées et peuvent causer de
graves blessures s'ils sont touchés.
AVVERTENZA: Non maneggiare i componenti del fusore finché non sono raffreddati.
Alcuni di questi componenti funzionano ad alte temperature e possono provocare gravi
ferite se vengono toccati.
VORSICHT: Die Fixieranlage sollte erst gehandhabt werden, wenn diese genügend
abgekühlt ist. Einige Teile der Fixieranlage erzeugen übermäßige Hitze und führen bei
der Berührung zu schweren Verbrennungen.
AVISO: No manipule los componentes del fusor antes de que se enfríen. Algunos de los
componentes del fusor funcionan a altas temperaturas y pueden ocasionar daños per-
sonales graves si se los toca.
Power Off the machine and check that the Fuser connection is fully seated, REP 1.17 . The
Fuser connections are OK.
