Improving Productivity
This section provides information you can use to do jobs quickly
and smoothly� You can improve productivity and speed up your
work just by learning the pointers and techniques we introduce
here�
• Choosing Paper Wisely (p� 116)
• Speeding Up a Print Job by Using Thin Paper First (p� 117)
• Replacing a Toner Cartridge without Stopping the Print Job (p� 118)
• Increasing a Paper Loading Capacity by Giving Priority to the
• Using Auto Drawer Switching to Its Fullest (p� 120)
• Increasing Print Speed by Giving Priority to Either Thin Paper or
• Speeding Up a Print Job Manually When Printing on Heavy 5/Heavy 6 Paper (p� 126)
• Speeding Up a Print Job by Giving Priority to Productivity Rather Than Gloss (p� 127)
Choosing Paper Wisely
Print speed changes depending on the type of paper and the basis weight� You can improve productivity by choosing
a paper consciously to meet your needs� First of all, see the following table�
Relationship between Types of Paper and Print Speed
Basis Weight
Types of Paper That Have Been
Registered in the Machine
(Standard Paper)
Print Speed
52 g/m
2
to 220 g/m
2
(14 lb bond to 80 lb cover)
Thin 1 or 2, Plain 1 or 2, Heavy 1 to 4
-
221 g/m
2
to 256 g/m
2
(82 lb cover to 140 lb index)
Heavy 5
2/3 as fast
257 g/m
2
to 300 g/m
2
(140 lb index to 110 lb cover)
Heavy 6
1/2 as fast
For example, if you use a paper type whose basis weight is 221 g/m
2
, Heavy 5 is a normal choice for the type of paper�
In this case, the print speed slows down to two thirds of the print speed of Heavy 4, whose basis weight is 220 g/m
2
�
In this way only 1 g/m
2
of the basis weight creates about 1�5 times difference in the print speed� You can improve
productivity by using a paper type whose basis weight is 220 g/m
2
, not 221 g/m

�
NOTE
• Only thin, plain, and heavy papers are selected from the standard types of paper and listed in the table above�
• Print speed changes not just according to the basis weight, by the type of paper as well� For the relationship
between standard paper and print speed, see "Types of Paper You Can Use for Calibration" at the end of this
document� (If you use group A as the base, the print speeds of group B and group C are two thirds as fast and one
half as fast respectively�)
• The print speed may differ from those in the table depending on the amount of images and the room temperature�
