Q1860-90918 Chapter 3 Printer operation 55
I/O menu
Items in the I/O (input/output) menu affect the communication between the printer and the
computer.
Table 21. I/O menu
Item Values Explanation
I/O TIMEOUT=15
5
to 300 Select the I/O timeout period in seconds. (I/O timeout refers
to the time, measured in seconds, that the printer waits
before ending a print job.)
This setting allows you to adjust timeout for best
performance. If data from other ports appears in the middle
of your print job, increase the timeout value.
Press [- Value +] once to change settings by an increment of
1, or hold down [- Value +] to scroll by increments of 10.
I/O BUFFER=AUTO AUTO
ON
OFF
Allocate memory for I/O buffering.
AUTO: The printer automatically reserves memory for I/O
buffering. Additional configurations are not required and the
I/O BUFFER SIZE menu item does not appear.
ON: The I/O BUFFER SIZE item appears (see the following
information in this table). Specify the amount of memory to
be used for I/O buffering.
OFF: I/O buffering is not performed and the
I/O BUFFER SIZE item does not appear.
When the I/O buffer setting is changed, any downloaded
resources (such as fonts or macros) have to be downloaded
again, unless they are stored on an optional hard disk or
flash DIMM.
I/O BUFFER SIZE=
100K
10K
and up This item appears only when I/O BUFFER=ON. Specify the
amount of memory for I/O buffering. The maximum amount
of memory available for I/O buffering is determined by the
amount of memory installed in the printer, the languages
installed in the printer, and other memory allocations that
must be made.
Press [-Value +] to change settings by increments of 10 (up
to 100 KB) or by increments of 100 (above 100 KB).
PARALLEL HIGH
SPEED=YES
YES
NO
Select the speed at which data is transmitted to the printer.
YES: The printer accepts faster parallel communications that
are used for connections with newer computers.
NO: The printer accepts slower parallel communications that
are used for connections with older computers.
PARALLEL ADV
FUNCTIONS=ON
ON
OFF
Turn the bidirectional parallel communication on or off. The
default is set for a bidirectional parallel port (IEEE-1284).
This setting allows the printer to send status readback
messages to the computer. (Turning on the parallel
advanced functions might slow the language switching.)
