Appendix C Performance Limitations
ZTP Platen Open
This option allows the user to have the platen open whenever forms are
reversed. Enabled is the default, used for most papers and labels. The feature
can be disabled as required by some multi-part forms.
Performance Limitations
Forms Type
The paper feed tractors on the ZT printer push the paper up through the print
station instead of pulling it through, as in the standard pedestal printer. This
limits the variety of forms the ZT printer can use. If the forms do not fall within
the range specified in Table 11, dot compression and line separation may
occur. The user should match the media to the application to ensure
acceptable print quality. Also, because paper is pushed from below the print
station, the last form in the tractors may not print fully or may not be presented
to the printer exit for retrieval.
All paper used in the ZT printer requires standard half inch spaced tractor
feed holes. Cut sheet and continuous friction fed paper is not supported. The
forms specified in Table 11 can have no more than one form per page
horizontally.
NOTE: If you use forms outside these limits, the print quality may not be
optimum, the printer may lose top-of-form, or the frequency of paper
jams will increase.
