• Check for AC line voltage to the LVPS / HVPS PWB.
• Check that the Connectors are tight and no contamination is present.
• Check the wiring harness from the LVPS / HVPS PWB for a short or open circuit.
• Replace the Main LVPS / HVPS PWB
Check the circuits and connectors for the Fuser Module.
Check the Heat Lamp for an open circuit.

10-200/ 300 Fuser Under/ Over Temperature Fault
10-200: The temperature of the Fuser is below of the normal operating range of 383°F ± 5°F
(195°C ± 5°C.)
10-300: The temperature of the Fuser is above of the normal operating range of 383°F ± 5°F
(195°C ± 5°C.)
BSD-Reference: BSD 10.1 Fuser
Initial Actions
Switch Off the power. Remove and reinstall the Fuser Assembly. Switch On the power.
Procedure
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.
Enter Diagnostic (EDM) Mode. Select: [DC330 Component Control, 109 Fuser Heat, Temp
A] to obtain a temperature reading from the Fuser. The Fuser temperature is within normal
operating range.
Y N
Replace the Fuser Assembly
If problem is intermittent, check the circuit of the Fuser Assembly for one of the following:
• All connectors are securely connected and no contamination is present
• Short Circuit or damaged wire. Repair as necessary
