How To Know Drum Unit Life - Brother HL 5030 - B/W Laser Printer Service Manual

2. HOW TO KNOW DRUM UNIT LIFE & PAGE COUNTER
If you want to know the drum unit life or the number of printed pages, you should print out the
Print Settings.
1. Printing out the Print Settings
(1) Press the Set switch three times.
(2) Print the Print Settings.
The page counter is printed at the right upper in Print Settings.
NOTE:
The descriptions printed in Print Configuration vary depending on the countries.
2. How to Read the Drum Unit Life
*As for U.S. model, it will correspond from October, 2003 production.
The drum unit life is shown by the bar at the bottom of Print Settings;
• It initially indicates 100% and gradually decreases.
• It indicates 0% when the Drum LED is blinking.
• It stays at 0% even if further printing is done.
The drum unit life is based on the page counter. If the average number of drum rotations is
more than the number of drum rotations in non-continuous printing, however, the drum unit life
is counted by the number of drum rotations.
Since the drum counter printed in Print Settings is an actual page counter after a new drum
unit is replaced, the drum unit life may be different from the drum counter.
For details on the difference between the drum unit life and drum counter, refer to the drum
unit life calculation below;
