Laserjet 5L Troubleshooting

 

OFF                      ON                  BLINKING The Indicator Lights provide a quick way to check the printer’s status.
Printer status messages
No lights are on or blinking	The printer is in SleepMode or has been disconnected.	If you want to print, press and release the Control Panel Button or send the print job. If no response, check the power cord.
On	The printer is ready to print.	No action is necessary. However, you can print a test page by pressing and releasing the Control Panel button.
Blinking	Print job in progress.	Let job finish printing.
Data Light and Ready Light both remain on	Unprinted data are in the printer.	Press and release the Control Panel Button to print the remaining data.
Data Light is blinking	Printer is in Manual Feed mode.	Make sure that the correct paper is loaded. Then, press and release the Control Panel Button to print.
Error Light remains on	Printer is out of paper.	Add paper.
	Printer’s EP door is open.	Close the door.
	Printer has a paper jam.	Clear the jam and resume printing.
	Toner Cartridge is either missing or not installed correctly.	Install a cartridge, being careful to position it correctly. NOTE: If the Error Light remains lit after checking for these problems, and there’s no paper jam, disconnect the power for 10 seconds, then reconnect to the power source. If, after taking these actions, the light remains on, a sensor or the DC Controller PCA will need to be replaced.
Error Light is blinking	The page may have too much data or may be too complex for the printer’s memory capacity.	Press and release the Control Panel Button to continue printing. There may be some data loss on the page. Hint: To avoid this in the future: See your printer driver help for more suggestions regarding printer memory usage. Reduce resolution to 300 dpi with your software. Install additional printer memory.
All lights remain on	Printer is indicating either an internal problem or a fatal error.	If you have added an additional memory card, try removing it. Disconnect the power for 10 seconds, then reconnect it. If all of the lights come on steadily again, try disconnecting the power for 15 minutes. If this error remains after completing the tasks above, see Chapter 7, "Troubleshooting."
All lights are blinking	Printer is initializing	No action is necessary.
	Memory card may be slower than 70 nsec	Remove the incompatible memory card and replace it with a 1, 2, 4, or 8 Mb, 70 nsec. or faster memory card.
Service and error messages Service errors prevent further printer operation until some action is taken. When there is a service error, all of the lights will turn on in a steady state. Press and hold the Control Panel Button to see a pattern in the lights. (The error will only be displayed as long as this button is pressed.)
	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 doesn’t clear the error: 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 persists the Formatter PCA will need to be replaced.
	Fuser Error. This indicates a fusing assembly malfunction. Note: Chronic fuser failures or fuser overheating or both are indicators of an uninterruptible power supply or battery backup being used with the printer. Uninterruptible power supplies (UPS) should not be used with the printer.	Unplug the printer for 10 minutes or more. If the error continues the fuser unit or the DC Controller will need to be replaced.
	Beam Error. There are a number of causes for this error, and some of the causes may be transient. (They may disappear.)	Power-cycle the printer by unplugging the printer and plugging it back in. If the error continues the Laser/Scanner Assembly or the DC Controller PCA will need to be replaced.
	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 clear the error: The Formatter PCA or the DC Controller PCA will need to be replaced.
	Scanner Error. Caused by a scanner malfunction.	Power-cycle the printer by unplugging the printer and plugging it back in. 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 the error persists the Laser/Scanner Assembly or the DC Controller PCA will need to be replaced.
	Formatter 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.
	Firmware Error.	The Formatter PCA will need to be replaced.
	Processor Error.	The Formatter PCA will need to be replaced.
