PRINTING OUT FAX WITH DARK LINES RUNNING VERTICALLY DOWN PAGE MAKING IT DIFFICULT TO READ. FAX MACHINE IS RICOH SUPER G3 4410NF

Make a copy with your fax machine. If your scanner is bad you should have a similar problem making copies. The same scanner is used to make a copy as is used to scan and send a fax. If the copy comes out bad your scanner is either dirty or bad. If you can see your copy but it just has a few lines running vertically up and down the page then you need to clean the scanner glass. This is a small strip of glass in the port where you feed it your originals.
Good Luck

The system needs to either be cleaned or calibrated. The print heads can be cleaned with rubbing alcohol and cotton swab. To calibrate, you may have to look in the manual for maintenance or calibration settings.

Where the original page that you wish scanned/faxed there will be a device called a "scan part". This device "reads" the paper to be faxed/scanned as it passes. It usually is found very near where the paper to be faxed goes in.
If there is a spec of debris on this part it will cause a fine line straight down the document. If its dirty, the document will be too! Just give it a good cleaning and you should be fine.

Colour printing is ok? Replace black PCU.

You can try using the menu to lighten the fax, but if all received faxes are dark, you may be experiencing a weak scan light. try making a copy instead of fax (which essentially is a fax printed to yourself) if also dark, its certainly your scanning imager that's failing. If that's the case I would recommend replacing the entire machine. Parts are expensive, and its a difficult to service part yourself. Also you may find that toner costs alone may pay for the replacement machine over this unit.

-Good Luck!

Check the drum- if there is any lines or ghost images replace it if not its problem with fixing unit.

Be sure that you cleaned your copy glass.

Pls. send the model of your machine.The G3 is fax protocol

Prints with a white line vertically down the page. How can I fix this?

If the print can be rubbed off then this suggests the fuser unit is not working correctly. It could be that the thermistor is covered with toner and making the machine think the fuser is hot enough when it's not.

The black line could also be caused by the fuser if one of the pick off fingers is coated with toner or has worn into the Teflon of the roller.

Does the machine show the lines when you print a page from memory - such as a counter or config page? If not, this would suggest the optical path is dirty. Try cleaning the glass and look at the mirrors inside the scanner to see if they are dirty/dusty.

There could be a couple reasons. One, it may be the person sending you the fax that has a problem with their machine. The easiest way to find out is, put a clean document in the feeder and make a copy. If the copy is clean then you know it is not a problem with your machine. The other possibility is that when Brother sells these new machines they only provide you with a starter drum and toner. Many times the drum may have defects and the machine does not detect these so you will not get a message telling you to replace it. If you do determine its your machine I would start by replaceing the drum unit first, then the toner.
Good luck

First and most important with Brother machines is , you need to use genuine brother supplies. Almost every time I service a brother and I find generic toner and drums cause the print quality issues. New supplies cost as much as a new machine. If not the supplies then it is laser or power supply.
