The nealy black copies sounds like the drum is going, try adjusting the exposure to light, if it comes out with the whole page the same way but just lighter than change drum. White line sounds like there is something on the coronas.

Sharp IR 2016 platine glass dirty


The cover plate is above the glass white surface of the scanner. If this is the same dirty stains will come out on copies.
The glass must be clean.
By feeding the original documents through the ADF, the scanner lamp is no longer the path to scan, the ADF is responsible for passing the original document over the scanner, while it remains still placed on the side under a thin glass is to a large glass side. This also must be clean, otherwise you will be black lines on each point or spot on the glass.
Good luck ...

White lines while sending/copying


Everything seems to indicate a dirty 'corona wire'. This seems to be the most common cause of vertical white lines running the length of a page when copying/sending. Below is a link to the User's guide for your machine with instructions for cleaning the corona and other care when using your fax machine. Best of luck.

Faint vertical lines on Samsung ML-2010


Was the toner remanufactured/ compatible?
Sounds to me like the doctor blade in the cartridge is 'gummed' up and not allowing the toner to flow evenly across the Developer roller......try another cartridge

On the konica 2223 when printing it leaves a dark thick line down the center of the paper.


Konica 2223 copiers are analog meaning the image that comes out on copies is a direct reflection off of the copy. Dirty mirrors in the optic section can cause a dark band, but it is more of a shading effect. Drum assembly's can be removed.The image drum has a cleaning section that uses a urethane blade to clean excess toner off of the drum after the copy passes through.It is simply called a "Cleaning Blade" these blades can be ordered through most online copier part stores. Last but not least is the "Upper Fuser Roller". this is the hot roller the paper passes through to "set" the toner to the paper. These are coated with teflon to prevent toner from sticking to them. They have "seperator claws" that keep the paper from adhereing to the roller, and they sometimes gouge the teflon. this exposes bare metal, and the toner can come off of the copies and stick to the roller.

Vertical lines on photocopies/faxes


The MFC-7420 Manual recommends cleaning the scanner glass and white plastic bar above it with isopropyl alcohol. Page 11-22 has a diagram.

I am having a similar problem but cleaning it did not work. But try that first.

Toner low???


How is the copy quality? Are copies light? If so then the toner hopper is not adding toner to the developer assembly in which case you must call a tech. If the copies are fine then the toner sensor is dirty or faulty and must be replaced.

Blank trace appears on printed copy


replace the toner cartridge, this is a case of low toner.

NOTE: you should never clean the drum on the toner cartridge it is sensitive to light and touch.

Printed pages look dirty


That black dust that fell out is the toner. When you shake a toner cartridge that shouldn't happen. It looks like you have a faulty toner cartidge and that need to be replaced! Now to make your printer prints cleanly and clearly after you replace the cartridge, you'll need to get someone to service the printer(the faulty toner cartridge more than likely spilled toner on your internal printer parts, cause the smudges). Sevicing would mainly entail, taking down the printer and removing any spilt toner! If you feel you are up to this, be cautious, because toner can be hazardous to your health if you accidentally breathe it in! hope this was helpful! regards babb
