Light status	Condition of the printer	Action
	PowerSave mode (or the printer is off). The printer uses PowerSave mode to conserve energy.	Low power consumption mode. Pressing the Go key on the printer control panel or printing will awaken the printer from PowerSave mode. Check the power cord if the above actions do not generate a response (and the power switch if your printer is powered with 220-240 volts).
	Ready The printer is ready to print.	No action is necessary; however, if you press and release the Go key on the printer control panel, a self-test page will print.
	Processing Self test page Form Feed The printer is receiving or processing data.	Wait for the job to print.
	Buffered data The printer memory is retaining unprinted data. A file has been sent to the printer that does not contain a from feed at the end.	Press and release the Go key on the printer control panel to print the remaining data.
	Manual feed The printer is in manual feed mode. The printer is waiting for a different size sheet of paper to be placed in the Single Sheet Input Slot or Paper Input Bin.	Check that you have loaded the correct paper, then press and release the Go key on the printer’s Control Panel to print. Manual feed is controlled by the software. If you do not want to be in manual feed mode, change the setting in your printer properties.
	Door open, no Toner Cartridge, or paper jam The printer is in an error state.	Check the following: The printer door is closed. The Toner Cartridge is correctly installed in the printer. There are no paper jams.
	Paper out The printer is out of paper.	Load paper into the printer.
	Memory out The printer ran out of memory in the middle of a print job.	The page being printed may have been too complex for the memory capacity of the printer. Press and release the Go key to print.
	Reset/Printer initialization The printer memory is being reset and all previously sent print jobs are being purged. Or, a printer initialization is taking place. All lights blink for 1/2 of a second or longer if initializing.	No action is necessary. However, you can reset the printer if you press and hold the Go key for five seconds.
	Fatal error All lights are on.	Turn the printer off and then back on. Press the Go key to see the secondary light pattern. Consult the list of fatal light patterns.
Fatal Errors
The printer may encounter a severe error, one that inhibits further operation. All LEDs will turn on or, in the case of an Accessory Error, all LEDs will start flashing. During this mode, pressing and holding the Go key down will reveal a pattern on the LEDs. Some LEDs might be on and some might be off, but it will be a non-changing pattern as long as the Go key is held down. This pattern can be used to identify what type of fatal error it was. For example, if all LEDs turn on, holding the Go key down might turn off all of the LEDs except for the Attention LED. This pattern would indicate that there is an Engine Error. For most of the errors listed here, turning the printer off for a short while will not clear the error (it is more serious than that), but it is recommended as a last resort. Remember, the error pattern will only be displayed as long as the Go key is held down.
Light status	Condition of the printer	Action
	ROM/RAM Error. An error was found with the ROM or RAM. The printer believes that the ROM is corrupted or an error has been found in the RAM.	Power cycle the printer by unplugging the printer and plugging it back in. If this does not clear the error, then: Unplug the printer, remove any optional memory, then power the printer back on. If the message clears, replace the memory card. If the error still does not clear the Formatter PCA will need to be replaced.
	Fuser Error. This indicates a fusing assembly malfunction. NOTE: Chronic fuser failures, fuser overheating, or both are indicators of an uninterruptible power supply or battery backup being used with the printer. Uninterruptible power supplies (UPSs) should not be used with the printer.	Unplug the printer for 10 minutes or more. If the problem persists either the fuser assembly or the ECU (Engine control unit) will need to be replaced.
	Beam Error. There are a number of causes for this error, and some of the causes may disappear.	Power cycle the printer by unplugging the printer and plugging it back in. If this doesn't correct the problem the Laser/Scanner Assembly or the ECU (Engine Cotrol Unit) will need to be replaced.
	Print Engine Error. The formatter and engine are not communicating.	Power cycle the printer by unplugging the printer and plugging it back in. If this doesn't correct the problem the Formatter PCA or the ECU (Engine Cotrol Unit) will need to be replaced.
	Printer Laser/Scanner Error. Caused by a laser scanner malfunction.	Power cycle the printer by unplugging the printer and plugging it back in. If this does not clear the error: Ensure condensation caused by moving the printer from a cold to a warm environment hasn’t occurred. Allow the printer to acclimate to the warmer room. If this does not clear the error, the scanner cable on the ECU (Engine Cotrol Unit), the Laser/Scanner Assembly, or the ECU (Engine Cotrol Unit) will need to be replaced.
	Firmware Error.	Power cycle the printer by unplugging the printer and plugging it back in. Disconnect the parallel I/O cable and try running a printer self test. Reconnect the parallel cable if the self test is successful and try host/printer communications again. If the error persists, the Formatter PCA will need to be replaced.
	Incompatible DIMM Error (Accessory Error).	Remove DIMM and cycle the power. If error persists,  the formatter needs to be replaced.
	Document Scan Engine Error.	Unplug the printer, remove and reattach the laser scanner, and then replug the printer. The document scanner unit needs to be replaced.
	Document Scan Engine NVRAM Error.	Unplug the printer, remove and reattach the document scanner, and then replug the printer. The document scanner unit needs to be replaced.
