Fig. 2-6 Installing the parallel interface card
In a printer dual-port configuration consisting of the standard serial interface
+ parallel interface, in an empty buffer and out of paper condition the printer
polls the two ports to see which one will be assigned. When a signal is
received by any one of the two interfaces, the printer switches to the
receiving interface and maintains this condition until the end of the print job.
Dual-port functionality is configured during printer set-up; in particular, active
emulation can be set on each of the two interfaces and can be changed in
run-time mode by means of a specific command.
2.5. INFORMATION FOR THE OPERATOR
After installation, the field engineer has the responsibility of informing the
operator on how to use the printer, how to replace the cartridge and how to
clear paper jams. It is suggested that a practical demonstration be given for
the following operations:
－ Using the operating panel, interpreting the error messages and
unlocking the machine whenever necessary.
－ Inserting a passbook and sheets of paper into the front insertion slot,
stressing the importance of avoiding the use of crumpled or torn paper
or passbooks with jutting spines. Show how to insert the sheet of paper
(automatic alignment) and the savings book (manual alignment).
－ Replacing the ribbon cartridge.
－ Removing a jammed document from the printer by using the lever for
lifting the upper mechanical assembly.
－ Inserting a check or tab in the optional check reader, making sure to
avoid using documents that are torn, wrinkled, folded or stapled together
