Best way is to use a vacuum and a paint brush and lightly brush and vac up dust. Careful not to damage some of the wires that may be under where the drum is. Never use canned air, I have seen many machines damage by a customer using canned air inside of a machine..

Hope that helps...

The drum unit is what you install the toner cartridge into. if you've changed toner, you've pulled out drum unit b4. open front cover, pull out drum unit and look at the top of it. you'll see a blue plastic tab. look down inside that slotted opening and you will see what look like guitar strings. i personally have used canned air to gently blow the toner/dust off of those strings. just be careful. last, but definetly not least, notice what side that blue tab is on, take the tab and slide it side to side several times, making sure when done to put it back on the side it was. that should do it.

Am machine drum damaged(pit marks)my machine model cannon6570i

Step1 Put on your latex gloves to protect the drum from skin oils. Cover a firm, stable working surface with a few sheets of clean newspaper to prevent spreading toner dust over your work area.
Disconnect your Canon copier from its power source and allow it to cool down for several hours if it has been used recently. Locate the access door to your toner cartridge and drum, typically located on the front or side panel depending on your specific model.
Step3 Remove the toner cartridge from its holding tray by lifting from both sides and pulling it up gently. Gently shake the cartridge to remove caked on dust, then place it on top of the newspaper sheets. Using your vacuum's hose attachment, clean away any toner dust from the cartridge's holding tray.
Lift the hinged door behind the holding tray to expose the copier's drum. Turn the spindle to the side of the door to rotate the drum. Apply a microfiber cloth to the outside of the drum as it rotates to clean away toner dust. Continue until the drum is as clean as possible.
Close the hinged door and replace the cartridge in its holding tray, ensuring that it is oriented the same way as when you removed it.
Reconnect your copier to the power source and make a test copy to ensure proper function.

I have a problem with the colour prints...there are different kind of lines all over the can i clean the laser heads?is there any automatically way?

Dots, Lines and smudges on the printouts are due to deteriorating cartridges and cleaning the green drum of the cartridge may help temporarily. Take out the cartridge and gently clean the roller/ green drum with a dry, soft, lint-free cloth wiping off the toner dots marks/ lines. (corresponding to the location where you are having a green line on the paper)
Also, make sure that the visible inside of the printer is clean and there is no spilled toner inside, which sometimes results in dots.
Moreover, streaks (thicker lines) and dots etc indicate faulty PCR Roller which is located behind the green drum inside the cartridge. Replace the Cartridge or get the PCR Roller changed by a professional.
Try cleaning the toners and see if it makes any difference. You would also have an idea about the toner drum/ parts quality etc and check if they need to be replaced. Furthermore, issues with Laser Unit like dust/ toner dust on the lenses and mirrors inside the printer usually result in faded or discolored prints. For instance, faded text/ picture at certain areas or any color missing when you print.

Hope it helps! Good Luck! Thanks for using Fixya!

Just copy file..always jam..messagge"papper jam

Causes for paper jams in Printers are given below:

* Dust or debris
* Rotating drum problem
* Toner or fuser complaint

Dust or debris

One of the main causes for paper jams is the presence of dirt, dust, or debris in your toner cartridge. The paper coming into the cartridge would get stuck. So clean your printer regularly. Remove the dust from the printer. Also find out whether any jams occurred in the sensor hole in the upper part of the rotating drum. Do not touch the roller while cleaning. If the oil in your body gets into the roller, the printing media cannot roll over it properly and you can't get rid of the printer problem.

Rotating drum problem

If there is no direct symptom of paper jam and still you cannot do printing properly, find whether it is because of drum problem. If the paper gets into the end gear of the rotating drum and gets stuck there, you cannot access the printing function. Switch off your printer and check the plastic arms of the printer drum. If there is any paper piece jammed in any of the arms, you can't continue printing. Here also cleaning is the best method to solve the problem. While cleaning, check the arms of the rotating drum.

Toner or fuser complaint

Toner complaint may also cause paper jams. It can be solved only by replacing it. When you switch on the loop back plug in, two flash lights appear; then it indicates paper jam. The oil spillage in toner can cause this problem. If the toner cartridge is not functioning properly, the same problem would be the result. The diodes or transistors in the fuser unit of the printer may get damaged and this can lead to fuser complaints. To solve this problem, you should replace it.

Dust on Drum...

I had this problem too. I took out the drum and vacuum the drum with a vacuum cleaner ( no brush ) while at the same time manually rotate the drum cyclinder. It worked. After a month or two, you might have to do it again. But everytime, it solved the dust problem.
