Drum cost how much is the drum for the 4450 fax machine

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

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.

Check your menu settings, you are set to MANUAL MODE

What kind of fax machine is it? There could be toner on the drum cartridge causing there to be lines.

You have a bad printhead unit(laser unit) only if the problem persist. The polygon mirror is not rotating within a specific amount of time.

You probably have a bad fuser unit, but first try a new drum.

lift up the rapid key flap on the keyboard. press the life key and I think the display will give a choice of press 3 key and enter.

If you see black lines on the drum, it is very likely that the drum unit is bad. Replace the drum unit and rest the drum counter. If you wait too long, you will cause toner build up in the fuser and will cost yourself several hundred dollars to get it replaced. More in labor than parts.

Use a soft cotton or very soft paper towel and wipe the excess toner from the drun. If there are lines worn in the surface of the drum, then replace it ASAP.

Press life "2" start for toner.

And life "3" start for drum.

These will reset the counters.

If you are having a "check drum error" then you have broken the sensor arm that is attached to your lid.

Call a technician in your area.
