Most likely you will need a high voltage power board. Or a drum or toner contact was damaged. Call a sharp dealership.

Our office uses a Sharp FO-4470 fax machine. this morning it is flashing an error on the display of High Voltage Error. Can anyone help with this?


It probably means that the high voltage driver board is blown. You'll have to take it to a service center for repair.

F2 error


Hi there,

Well F2 error codeis on a variety of Sharp copiers, the F2 error code would normally be accompanied by a sub code that indicates the fault, You may please check out the following -

  • F2 with sub code 00 - Toner Sensor problem, ID pattern reading error;
  • F2 with sub code 02 - Toner Motor problem, check toner dispenser motor;
  • F2 with sub code 31 - Image Density error, Check the light level or the drum surface reflectivity;
  • F2 with sub code 32 - Drum Mark sensor, missing/dislocated mark or sensor faulty. Sensor cannot scan mark properly;
  • F2 with sub code 33 - grid voltage wrong, either too high or too low;
  • F2 with sub code 35 - grid voltage correction will not work during simulation;
  • F2 with sub code 37 - drum mark sensor adjustment required.
You may post further comments for more help or information......

Good Luck!!

Thanks for using FixYa!!

Papers come out with black streeks on them from my sharp FO 4450


If everything is coming out with streaks, it's most likely your cleaning blade which is part of the drum cartridge. I've also seen this from 3rd party toner. Get Sharp toner for your Sharp fax if you don't have it already. If your black streaks are only on copies and sent faxes, this indicates that your scanner is dirty. It's located where you feed your paper in. Lift this part up and you'll see a strip of glass running front to back about 1/2 inch wide. Clean it and that will get rid of lines.
