Toshiba e-Studio 320P
Service checks 04
Fuser service check
When toner is partially fused to the paper, it is usually caused by low fuser temperature.
The line voltage to the printer must be within the following limits:
• 90 V ac–120 V ac for nominal–100 V model printer
• 100 V ac–127 V ac for the nominal–110 V model printer
• 200 V ac–240 V ac for the nominal–220 V model printer

Fuser assembly LVPS |
Unplug the printer and disconnect the fuser heater cable from the LVPS card connector (CN3). See “Low voltage power supply (LVPS)” for more information.

Fuser assembly | If the fuser heater comes on and a fuser failure error code displays, be sure the thermistor is firmly seated in connector J18 on the controller card assembly. (The thermistor cable goes through the frame by way of a connector.) Unplug the printer and disconnect the thermistor cable from the controller card (J18). Measure the resistance of the thermistor. The resistance measures approximately 240K to 400K ohms when cool (approximately 40°C or 104°F) and 1.5K to 3K ohms hot (immediately after running a printout). Replace the fuser assembly as necessary. |
