4500-E320/E322 Parallel port Parallel port lets the user enable or disable the parallel port. If the port is not being used, disabling it frees allocated memory to be used to process print jobs. Note: Optional parallel ports are not available to change in some network models. Perform the following steps to change the Parallel port setting: 1. Enter the configuration mode. See "Configuration mode" on page 3-14 for more information. The Parallel port (Ready) light comes on solid. The current Parallel port setting is indicated by the off/on/auto (Press Button) light. When the light is off, the parallel port is disabled. When the light is blinking, the parallel port is enabled. 2. Perform a brief button press to select the parallel port setting. 3. Perform a long button press. All lights blink once, indicating the setting is saved. 4. Exit the configuration mode by turning the printer power off. Off/on/auto ❍ ● ✳ Setting value Parallel port is disabled. The printer doesn't receive data from the parallel port. Parallel port is enabled with a fixed buffer size. The buffer size is set from a utility such as MarkVision. Note: This light state is only displayed if the current value for the Parallel port enabled setting is a fixed value. The user can't set the value by pressing the button to cycle from the off value to the on value, that is, the button press cycles from off to auto. Parallel port is enabled with an automatic buffer size. The printer determines the buffer size based on available memory and other printer settings. Diagnostic aids 3-23
