Paper
Note:
Use recycled paper, labels, envelopes, postcards, overlapping
forms, and continuous forms with labels only under normal
temperature and humidity conditions as follows:
Temperature 59° to 77°F (15° to 25°C)
Humidity 20% to 60% RH
For continuous multi-part forms:
❏ The form sheets of continuous multi-part forms should be
securely joined together along the left and right edges by
crimping or spot-gluing. For the best printing quality, use
multi-part forms joined with spot-gluing.
1 inch
or less

❏ When using crimped multi-part forms, note the following:
❏ Crimping should be pressed in from the original sheet
side and go completely through all copy sheets.

❏ The binding area should be flat and should have no creases.
❏ The sprocket holes of all sheets in the form should be
aligned properly.
❏ The binding position should be outside the printable area.

Pre-printed paper
Pre-printed paper is paper with white space in the middle and
ruled lines, letters, or figures printed in the top and bottom
margins. The margins are printed the first time the paper is
loaded in the printer, and a document is printed in the white
space the second time the paper is loaded in the printer. The
margin areas are often used for letterheads, borders, and so on.
You can make your own pre-printed paper or you can
purchase it.
You cannot preprint in the area with the diagonal shading
shown in the illustrations below, and you can preprint only
with colors whose reflectivity is under 60% (for instance
black). Avoid punching holes in the restricted area shown
below because punctures are also recognized as colors whose
reflectivity is under 60%.
Before printing on pre-printed sheets, verify that the area your
document will print on does not overlap the pre-printed area
by printing separate sample sheets and comparing their
printed areas.
