Hello thanks for using fixya

You should try this solution:
Remove the power cable from the printer, Press power then wait a few seconds, then Press power again. Now plug in the power cable and try to turn the printer on, It will boot, If it does boot then it means the power supply is not exactly correct in printer. So you may need another power supply

I hope this solution will helpful 4 u

HP Deskjet 3744 Printer

i need driver deskjet 3744

i Need printer driver of HP Deskjet 3744.

You can first try to connect the unit to a different wall jack , if the adaptor is not warming up after a few minutes , its a concern with the power adaptor .

U can call Hp parts store to get the adaptor.however u need to give them the part number (which will be located on the adaptor itself )

Parts Store Number - 1-800-227-8164.

Thanks.

Just pick your operating system.

1. push the adaptor's jack firmly
2. change the adaptor jack(after checking the power voltage with multimeter the out put voltage should be 32v and 16v)
3.replace the cartrige
