“DRUM LIFE” or “REPLACE DRUM” is a rough indicator that the image drum cartridge has reached the end of its life. If there are no problems with print quality even if this message appears, continue to use until there is no toner left. When out of toner, replace the image drum cartridge and toner cartridge together.
A degraded drum unit can cause streaks, smudges, and blank spots on your printed page even if you just inserted a new printer toner. While a broken drum unit won`t break your printer, it will just fail to stop printing at a certain point.
The drum unit may need replacing if you notice the printer producing blurry, low-quality images. Black or colored toner spots on printouts also indicates a failing drum unit. In some cases, horizontal lines may develop across the printout every time the paper passes the failing part of the drum.
Drum Error typically appears when the corona wire on the drum unit needs to be cleaned or when the drum unit needs to be replaced. If you replaced the drum and the message appeared or continued to appear immediately after installing the replacement drum, click here. 1. Clean the corona wire inside the drum unit.
Use an activated toner cloth, stretched tautly, and carefully wipe down the drum exterior to remove loose toner. Then use a cotton ball saturated with 99% pure isopropyl (rubbing) alcohol. Clean any patches of stubborn toner still attached to the drum. Use toner cloth or lint-free microfiber to clean the print rollers.
Why do I need a drum? Without a drum unit, the toner powder in the cartridge cannot be transferred onto the page. The two parts work together to create a print! You can`t have one without the other and expect the printer to work properly.
There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used, number of pages per print job and so on. Under ideal conditions, the average drum life is estimated at approximately 12,000 pages.
You can set when to display the “Image Drum Near Life” message. Press [Device Settings] > [Admin Setup] > [User Install] > [Drum Near Life Timing] on the touch panel to change the setting. Available values are from 500 to 3,000 (in 500 increments).
Shelf life is a period of time the components can be stored and still be suitable for use. A laser printer drum`s shelf life is approximately two years if the drum is still in its protective bag. Leave your printer`s drum in its protective bag until you`re ready to install the component.
Found within any laser printer, a toner drum is a component which transfers the toner powder stored within the cartridge onto the paper. It comes in the form of an electrically-charged cylinder. The printer will take toner powder from the cartridges and apply it on to the drum unit`s roller.
Over time, the cycle of repeated charging and discharging, combined with the electrical charges that printers use, can break down the chemicals in an imaging drum. As the chemicals break down, the drum`s power to attract toner becomes weaker, while the edges between charged and uncharged areas become more blurred.
Striking the head of the drum changes its shape and compresses the air inside the shell. The compressed air presses on the bottom head and changes its shape. Then, these changes are transmitted to the drum shell and reflected back, and this action is repeated, creating a vibration.
Remove dust from the shells using a feather or “Swiffer” type duster. Use a soft clean cloth for cleaning/polishing – microfiber cloths are ideal. Don`t use paper towels as they are too abrasive. Apply the polish/wax then carefully wipe it off turning the cloth over frequently.
Check that the same IP address is set for the machine and the machine`s port setting on the computer. Check that the IP address is not duplicated by another device. Check that the correct IP address, subnet mask, and gateway address are set. If using OKI LPR Utility, check the IP address setting with OKI LPR Utility.
Carefully wipe off any dirty areas visible on the drum. If the drum unit is dirty, apply some rubbing alcohol onto your lint-free cloth and carefully wipe the body of the drum unit.
Use Vinegar as a DIY Washing Machine Cleaner

If you have the all clear, pour 2 cups of vinegar into your detergent dispenser and run your washer on the hot cycle. “When it is complete, add a half-cup of baking soda to the drum and run another hot cycle,” she says.

To avoid print quality problems, DO NOT touch the surface of the drum unit, only the wheel on the end.
The toner cartridge is the container that holds the toner powder, which creates text or images on the page. The drum unit is an electrically charged cylinder that transfers that toner to paper.
There are many factors that determine the actual drum life, such as the temperature, humidity, type of paper, type of toner used and so on. Under ideal conditions, the average drum life is estimated at approximately 15,000 pages.
Laser printers use a single drum, but may have more than one toner cartridge. Monochrome models use only black toner, and color laser printers have four cartridges: black, cyan, magenta and yellow. When used in combination, the printer produces all colors, hues and shades of gray.
The drum uses static electricity to attract powdered toner to the drums cylinder. The drum rolls the toner onto the paper in the form of your print. The toner is melted & pressed onto the paper by heat from a fuser as it passes through its rollers. Your print comes out of the printer.
a line printer that uses a rotating drum with raised characters, against which the paper is pressed.
Old printer drivers (software installed on the PC that communicates with the printer) can also cause the printer spooler to fail. Search the website of your printer manufacturer for a new `printer driver` which is an updated version of the software and install the most up to date driver on your PC.
