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 I/O TIMEOUT=15 5 to 300 I/O BUFFER=AUTO AUTO ON OFF I/O BUFFER SIZE= 10K and up 100K PARALLEL HIGH YES SPEED=YES NO PARALLEL ADV ON FUNCTIONS=ON OFF Explanation 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. 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. 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). 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. 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.) Q1860-90918 Chapter 3 Printer operation 55
