Toner is the powder ink that latches on to the paper to create text and images. It is stored in the toner cartridge. An image drum is the unit that copies the text and images from the computer and then transfers them to the paper, along with the toner.

Many consumers have the "If it ain't broke, don't fix it" mentality. But the replacement of a drum unit is vital to laser printers' health. A degraded drum unit can cause streaks, smudges, and blank spots on your printed page even if you just inserted a new printer toner.
Moisten a cotton ball with 99 percent pure isopropyl alcohol, and then use it to clean off any patches of toner that have adhered to the drum.
What is the drum unit? The drum unit transfers the toner to the paper. The laser printer puts the toner on the roller called "The photosensitive drum" inside the drum unit, and then prints letters and images by fixing toner to the paper by heat and pressure.
To clean the drum manually, wipe its surface (or just the area bearing the offending marks) with a cotton swab. The swab can be dry. For extra cleaning power, dip it in rubbing alcohol, then clean carefully But do not use a scrubbing or wiping motion, which might damage the drum.
Most HP laser printers have the drum unit incorporated into the toner cartridge. But for Brother laser printers, the drum units come separately so you will need to replace these in addition to the toner cartridges.
Imaging or drum units are an essential maintenance part of a laser printer and as such do not need to be replaced as often as the toner cartridges. Imaging units such as the MLT-R116 have a very specific role in the printing process. The imaging unit contains a metal cylinder that the laser beams your print out on to.
The toner is charged with a high negative charge and applied to the drum. Because of the electrical charge, the toner is only attracted to the drum where the laser wrote the image. Pickup rollers applied to the top of the paper are used to pick up paper from the paper tray and begin feeding it through the printer.
Which printer part gets the toner from the photosensitive drum onto the paper? Corona assembly The transfer corona assembly gets the toner from the photosensitive drum onto the paper.
- Blurry Prints. If your printer is churning out blurry pages, it either means that your printer drum is damaged and in need of replacement or that you need new ink toner.
- Black Spots.
- Poor Print Quality.
- Other Signs and Symptoms.
Turn the edge of the drum unit toward you by hand while looking at surface of the suspected area. Wipe the surface of the drum gently with a dry cotton swab until the mark on the surface comes off. Put the toner cartridge firmly into the drum unit until you hear it lock into place.
That will cause the cartridge to dry out. It can happen in as short as 3-4 weeks. It is not a bad idea to print out something once a week, but if you have a color printer, you would want to make sure it is also printing something with color.
The printers laser beams your print onto a metal cylinder called a drum. Using static electricity, the drum attracts powdered toner from its cartridge to the drum. The drum rolls the toner onto the paper in the form of your print. The toner is melted onto the paper by heat from a fuser as it passes underneath.
approximately 15,000 pages
Because the photosensitive coating on the drum becomes conductive when exposed to light, the charges on the surface of the drum exposed to the laser conduct to the base layer, which is connected to a ground. The result is a near zero volt image and a negative background.
The Brother machine will display a 'Replace Drum' or 'Drum Stop' message when the machine has printed approximately 15,000 pages. The drums should be replaced as a set in order to maintain print quality. Unlike the toner cartridges, the drum change is not automatically detected by the machine when they are replaced.
