PRINTER SECTION
 Paper Jam/ Multi-Feed Rate
Note : The above rates are measured under the following conditions.
Paper size: Regular size
Newly unpackaged paper were used.
The 500-sheet cassette does not support special paper.
Multiple-sheet feed rate: Conditions when adding new paper onto remaining
paper in the tray or cassette are not considered.
 MPBF
Main unit: 50,000 pages

Number of images: As color printing uses 4 color images (Y, M, C, K),
four images are counted per page.

Monochrome : 50,000 × 1/3 = 16,700 images
Color : 50,000 × 2/3 × 4 colors = 133,200 images
MIBF : 16,700 + 133,200 = 149,900 images (approx. 150,000
images)
