Pull the drum and toner cartridge out and spray inside of printer with canned air. Make sure you keep the can upright when spraying. Uncllip toner from drum and spray the area on the drum where the toner clips on. Move the corona cleaner from one side of the drum to the other a couple times, reseat toner in drum, put cartridge back in printer and print a few pages to remove toner that may have settled after spraying.

Refilling toner in xerox phaser 6280


I would not advise you to refill a toner cartridge becausethe toner powder is very fine and you do not want to breath in this tonerpowder.When the toner cartridge is exhausted or empty then theprinter will not be able to print further documents or the prints will be veryfaint.You may be able to print a few more pages by removing thetoner cartridge and shaking the toner cartridge in a horizontal position a fewtimes and then placing it back into the printer.This will give you an opportunity to print a few more pages and giveyou time to purchase a new toner cartridge for your printer. A cheaperalternative is to purchase a re-manufactured toner cartridge for your model printer.A re-manufactured printer cartridge also replaces worn partsas well as refilling with toner powder.

You need to clean the ink cartridge. Check for software on you computer under programs. You could also put some rubbing alcholol on a parer towel and lightly rub the print heads clean.

Replaced fuser and toner units now only prints black pages


Printing on a laser printer has 3 steps:

1. electro-statically charging the "drum", at various tiny "pixels",
to identify where the toner-powder should be placed.

2. feeding toner-powder onto the charged drum.

3. making the fuser produce heat to "bake" the ink onto the printer.

So, a failing unit or failing electronics would "charge" *ALL* of the drum,
thus putting black ink EVERYWHERE onto the page.

Take the printer to a qualified technician.

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
