Image Drum Precautions
The image drums are fragile. To avoid damage to new drums, take these precautions while
handling the new image drum cartridges:
Avoid touching the green drum surface.
Be careful not to set the cartridge down on anything that might scratch the green drum
surface.
Keep the drum from exposure to direct sunlight and don't let it sit in room light for more
than 5 minutes.
Leave the image drum in the package until you are ready to install it in the printer.
Image Drum Life
The life of the image drums depends on a number of factors, including
operating temperature
humidity
type of paper you use
number of pages per job.
Each time you print or turn the printer on/off, the drums have to rotate to start up and to wind
down. Frequent one-page print jobs will age your drums more quickly than multiple-page print
jobs.
For simplex (one-sided) printing with 5% area coverage, the image drums should normally last:
about 26,000 pages at 3 pages per job, or
about 39,000 pages, continuous printing
Important! These numbers are approximate since you won't print the same number of
pages each time, the amount of color will vary from page to page, and environmental
conditions and print media used may vary.
When an image drum nears the end of its life, the CHANGE DRUM message appears on the
display. You should have a new image drum cartridge and a new toner cartridge on hand at this
point. Replace the image drum when the print becomes faint or begins to deteriorate.
Cleaning the LED Arrays
When to Clean the LED Arrays
Clean the corresponding LED array every time you install a new toner cartridge.
If faded vertical stripes appear on your printed pages between toner changes, clean the
LED arrays.
