while data is in the printer, a form feed pending will occur. Once the data the printer has received is completely formatted and no more data is in the I/O, the partial page will be ejected due to the form feed pending. Normal printer operation When power is supplied to the printer, all LEDs go on and then off. The LEDs will sequence on and off, one after the other, from the first LED (Go key/LED) to the last LED (Attention LED). If an error is detected or if paper is out, the printer will enter that error mode. When data is downloaded to the printer (during Ready mode), the Ready LED will blink. When the printer stops receiving data, the Ready LED may continue to blink while the printer formats the data. If an error occurs, the printer will enter that error mode and display the error on the Control Panel. Error priority The highest priority error will be displayed if multiple errors occur simultaneously. The priority of errors, from highest priority (most important) to lowest, is: 1 Fatal Errors 2 Door Open/No Toner Cartridge 3 Paper Jam 4 Paper Out 5 Memory Error While in any of the errors except Fatal Error, a reset may be performed by pressing and holding the Go key for five or more seconds, or unplug to reset. When the reset completes it will return to the error condition. If the error was cleared by the reset (such as a Memory Error), the printer will return to Ready mode. 30 Chapter Product Operation C4224-90962
