Reset the error. (Enter simulation mode by pressing # * C *) display will go off. Press 1 4 Start. The machine will restart automatically. If the error continues, check the thermistor connection and the lamp connection as well. Replace if required. Replacing the PCB is the final step.

Error Code H2


H2 means the thermistor is open or defective.

Try to press the copy button when h2 appears you'll see the sub 00. You dont need to replace the whole fuser unit. Try first to cancel the trouble by entering the simulation.

Try to press the # - interrupt- C- interrupt (one after the other.) then enter 14 then copy button. If it doesnt work replace the thermistor.

The last part that you'll replace is the main board but that rare. Mostly the thermistor is defective when that trouble appears. Hope it could help you a lot.

Can't print or copy with my toshiba e studio 161


H2 indicates thermistor open.

U can enter simulation mode and input "14" to clear the message.

If happen again, u need to check following:
Thermistor
Control PWB
Fusing section connector disconnection
The fusing unit is not installed.

Perform the following procedure to enter the simulation mode.
"C" key AUTO/TEXT/PHOTO key
"C" key AUTO/TEXT/PHOTO key
Main code Start key Sub code Start key
(Note:Perform the first four key strokes quickly allowing no more than one
second between key strokes.)

• The Fusing Roller Sub Thermistor does not
detect the required temperature within 30 sec.
after a warm-up cycle has begun; therefore, the
copier does not complete the warm-up cycle.
• The temperature of the Fusing Rollers does not
reach the required level even after the set period
of time has elapsed during a warm-up cycle.
