For USA and Canada
 KONICA MINOLTA strongly recommends that you do not refill the toner cartridge provided with your printer. 
We also strongly recommend that you continue to use only genuine KONICA MINOLTA brand replacement

MINOLTA machine, we strongly recommend the use of genuine KONICA MINOLTA supplies.
 
IMPORTANT
 
For UK and other countries
 KONICA MINOLTA machines are designed to work with toner of a particular specification and will work to 
a level of optimum performance when used with genuine KONICA MINOLTA branded toner cartridges. 
KONICA MINOLTA cannot guarantee this optimum performance if toner or toner cartridges of other 
specifications are used. KONICA MINOLTA does not therefore recommend the use of cartridges other than 
genuine KONICA MINOLTA branded cartridges with this machine.

Drum unit6
A new drum unit can print approximately 25,000 A4 or Letter size single-sided pages at 1 per/ job.
Note • 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 25,000 pages. The actual number of pages that your drum will print may be significantly 
less than this estimate. Because we have no control over the many factors that determine the actual 
drum life, we cannot guarantee a minimum number of pages that will be printed by your drum.
• For best performance, use only genuine toner. The printer should be used only in a clean, dust-free 
environment with adequate ventilation.
• Printing with a third-party drum unit may reduce not only the print quality but also the quality and life of 
the printer itself. Warranty coverage therefore cannot apply to problems caused by the use of a third-
party drum unit. 
 
Drum End Soon message6
If Drum LED blinks, it means the drum unit is near the end of its life. We recommend that you replace the 
drum unit with a new one before there is a noticeable deterioration in the print quality.
Replace Drum message6
If Drum LED lights, it means the drum unit should be replaced. Please replace it to a drum unit.
