1. Maximum printing rate is the maximum number of pages of the indicated size and configuration that can be
printed at the constant speed of paper movement shown for each printer. Rates for pages of different sizes and
configuration can be calculated by dividing the form length into the printer speed. Actual printing rate will be less
if the printer cannot reach this rate due to complexity or density of the data or the ability of the system to deliver
data at this rate.
2. Maximum usage is based on operating 7 days a week, 24 hours a day, at maximum printing rate with normal
maintenance and operations activity. IBM does not recommend reaching this monthly maximum on consistent
basis.
Printable Area
The printable area depends on the size of the form being used. The Infoprint 4000–IR1/IR2 and –IR3/IR4
printers can print from perforation to perforation when using roll forms. However, when printing on folded
forms, the printing may be degraded in areas near a folded perforation, an internal perforation, or any cut
in the form because of the “tenting” (fold memory) of the form.
Figure 30 on page 87 shows an example of the printable area of a standard, letter-size roll form for the
Infoprint 4000–IR1/IR2 and –IR3/IR4 printers. Notice that the media origin is located in different corners for
wide and narrow forms. Although the maximum printable area for narrow forms is 8.5 by 17 inches, and
the maximum printable area for wide forms is 17 by 17 inches, the examples show the printable area for
letter-size forms.
