Loading Paper
This section describes how to load paper.
Caution for Paper Curl
If paper jams or poor print quality occur, paper curl is often the cause. The paper stiffness, direction of curl, and amount of curl have a strong influence on how well the paper is transported through the machine. When loading paper, always adjust the curl amount to the appropriate level as described below.
Relationship between Paper Grain and Curl
Paper stiffness depends on the direction of the paper grain. Paper tends to curl in direction parallel to the grain.
When using coated paper whose paper weight is 28 lb bond (105 g/m2) or less, or thin paper whose paper weight is 16 lb bond (60 to 63 g/m2), we recommend using paper with the grain parallel to the feeding direction of the paper.
Correcting Paper Curl
In order to prevent problems resulted from paper curl, it is necessary to uncurl paper appropriately.
The amount of curl that may cause problems depends on the paper type and thickness. Refer to the instructions below to correct the paper curl so that it is within the acceptable range, and then reload the paper. Paper that has waves, curled edges or folds cannot be used.
Measuring Paper Curl
Place the paper on a horizontal surface. Place a ruler against the leading edge relative to the paper transport direction, and measure the curl at both ends. If it is a down curl, flip the paper over before measuring the curl.

IMPORTANT |
For small and thick paper such as postcards, the difference between the amount of inner and outer curl must be adjusted to less than 1/4" (5 mm) in addition to the conditions given below. |
Acceptable Curl Range
Acceptable curl range when the curl is perpendicular to the feed direction
If you feed paper from the main unit or the POD Deck-D/Secondary POD Deck-D
We recommend using paper which curls up or down 1/4" (5 mm) or less regardless of the paper thickness.
If you feed paper from the POD Deck Lite-C/POD Deck Lite XL-A
If you feed paper from 82 lb cover to 110 lb cover (221 to 300 g/m2) in weight and whose length in the feeding direction is 7 7/8" (200 mm) or less, we recommend using paper which curls up 1/4" (5 mm) or less. We do not recommend using paper which curls down.
For paper other than above, we recommend using paper which curls up or down 1/4" (5 mm) or less.
If you feed paper from the Long Sheet Tray-D
If you feed paper whose weight is 28 lb bond (105 g/m2) or less, we recommend using paper which curls up or down 3/8" (10 mm) or less.
If you feed paper whose weight is from 28 lb bond to 60 lb cover (106 to 163 g/m2), we recommend using paper which curls up 3/8" (10 mm) or less, or paper which curls down 1/4" (5 mm) or less.
If you feed paper whose weight is from 61 lb cover to 95 lb cover (164 to 256 g/m2), we recommend using paper which curls up 1/4" (5 mm) or less. We do not recommend using paper which curls down.
Acceptable curl range when the curl is parallel to the feed direction
If you feed paper from the main unit or the POD Deck-D/Secondary POD Deck-D/POD Deck Lite-C/POD Deck Lite XL-A
When the curl is parallel to the feed direction, there is a gap between the paper and the size change plates on the paper deck, and there is a risk of paper being fed at a slant. If you cannot avoid using curled paper, always ensure that the curl is within the range given in the graph below.
However, Heavy Paper or Card Stock (60 lb cover to 147.9 lb cover (164 to 400 g/m2)) with this kind of curl cannot be used. With Heavy Paper or Card Stock (60 lb cover to 147.9 lb cover (164 to 400 g/m2)), transport problems may occur regardless of the amount of curl. For LTR or smaller sizes, we recommend using paper with the grain parallel to the long edge (A). For sizes 11" x 17" or larger, we recommend using paper with the grain parallel to the short edge (B).
