– Specify TABS in the ordered stock statement so that
dynamic width checking is disabled.
– You may define the ordered stock statement at the job or
the system level of a JSL. If you define it at the job level,
you must ensure that the ordered stock command defined
from the initial JDE and JDL to a selected JDE and JDL
are exactly alike. The reason is that the system contains
an internal mod and pos table that keeps track of the
current mod and pos values for the job, and is used for
jam recovery. This table is initialized at report setup time
through values that were entered in the Properties
window for each tray (accessed from the Printer Manager
window).
When a JDE or JDL DJDE with an ordered stock
command is specified, the system reinitializes its internal
mod and pos table with values in the DJDE JDE or JDL, if
it finds that the ordered stock information in LCDS Setup
window is different from the values defined in the DJDE
JDE or JDL.
However, if both commands are alike, the system does
not reinitialize the internal mod and pos table. If you check
for initialization of the internal mod and pos table, the tab
stocks start purging before every tab is imaged (because
mod and pos are always initialized for every tab page).
• Purging tab stock: The printer can purge tab sheets
whenever the tab cycle is not in sync with the formatted data.
This may be caused by paper jams with multiple jobs running
in succession.
Example: Here is an example of a typical application
scenario:
– Tray two contains the tab stock which has MOD=5.
– Two tab stock jobs to run in succession. Both jobs require
tray 1.
– Job 1 starts with Tab 1 (located in the upper right corner
of a portrait page) and Job 2 must start with Tab 5
(located in the lowest right corner of the portrait page.)
– The number of tabs Job1 will use is 2.
