Replace 9541 Drums

This knowledge base article shows you how to Replace the 9541 Drums on your number plate printer. Ensure your replacements are genuine OKI consumables for plate quality and legality reasons. Instructions that follow assume you are directly facing the front of the machine.

Your Pro Series 9541 printer will let you know when it is time to replace a drum. First you’ll see warning messages on the display screen found on the control panel, warning a particular drum is getting low. This is when you need to order a replacement if you don’t have any. The message will change and prompt you to replace it once the drum is empty, it may even stop printing.

Note: Drum units are sensitive to light, so always cover them when out of the machine and avoid direct contact with the green cylinder.
