Replacing the Image Drum (MB461, MB461+LP, MB471, MB471w, MB491, MB491+, MB491+LP, ES4161 MFP, ES4191 MFP, MPS4200mb, MPS4700mb only) Life Duration of Image Drum When the [Image Drum Near Life] message appears on the display screen, prepare a replacement image drum. If you continue printing, the message [Please Replace the Image Drum] will be displayed and printing will stop. A guideline for replacing the image drum is every 30,000 pages or so for A4 sized paper (with single-sided printing). However, this number of pages is for printing with general conditions (3 pages at a time). Printing one page at a time reduces the drum life by about half. The actual number of printed pages may be halved again relative to the above guideline, depending on the printing conditions. Note  The actual number of pages you can print with the image drum depends on how you use it. The above guideline may be reduced by more than half, depending on the conditions of printing. Note  The print quality may deteriorate after the toner cartridge has been unpacked for a year. Replace it with a new one. Replacing Consumable Items Procedure for Replacement Note  The image drum (the green tube) is very delicate. Handle it carefully.  Do not expose the image drum to direct sunlight or very bright interior light (approximately more than 1500lux). Even under the normal interior light, do not leave it for more than 5 minutes.  To ensure optimum performance, please use original Oki Data consumables.  Service for problems caused by the use of consumable items other than genuine OKI consumables is not covered under the warranty or in the maintenance contract. (This does not apply to all faults occurring with non-original Oki Data products; however, please bear this in mind when using them.) 1 Open the top cover and remove the used image drum. Remove the image drum upward slowly. If the image drum is removed, the toner cartridge is also removed. 8 Be sure not to throw used image drum and toner cartridges into WARNING fire; toner in the cartridges may scatter and ignite, causing burn injuries. 2 Install a new image drum.  Take the new image drum out of the wrapping bag. Remove the silica gel. Silica gel Note  Always use a new image drum. An image drum that has been attached or used on another printer cannot be used. Maintenance - 173 -
