Toshiba C443 error code
Fuser heating fault
Toshiba C443 usually indicates a fuser heating fault: feedback from the heating unit is invalid during startup or warm-up. It belongs to the C4xx fuser family.
What does this error mean?
The exact meaning varies slightly by model, but the affected assembly is the fuser: the heating element, thermistor or thermostat. On Toshiba printers, fuser error codes remain stored after the fault has been resolved and must be cleared by a technician.
What can you safely try?
- 01Switch the printer off at the main power switch, wait at least 10 minutes for the fuser to cool down, then switch it back on. Many error codes are temporary and disappear after a full power cycle.
When should you call a technician?
Call a technician to check the fuser assembly; clearing the code also requires a technician.
Do you rent out or manage printers?
If you manage the printer at a customer’s site, you can record the fault on site in PrinterMS using QR issue reporting, and any parts used are automatically added to its service history. See printer fleet management.
