Laserjet 6P Troubleshooting

 

There are five Status Panel lights on the printer:
Light Pattern	Description	Recommended Action
	The printer is in Ready Mode and is ready to print.	Press the GO button to print a demo page. Press the GO and RESET buttons to print a self-test page.
	The printer has received data.	If the Ready light is flashing, the printer is processing the data—wait for the next page to be printed. If the Data light and the Ready light are both on for an extended period of time (the Ready light does not begin to flash), press the GO button to print the next page. A document or page may take a long time to print if, for example, the document or page contains complex text or graphics.
	The printer is warming up or resetting after you have pressed the RESET button. The lights on the Status Panel “cascade” (each light turns on and off sequentially) until the printer is ready to print.	Wait for the printer to become ready.
	Tray 1 (the MP Tray) is empty.	Add paper to the tray. If the Tray 1 light is flashing, the printer is waiting for paper to be manually fed into Tray 1. Once you have inserted the paper, you must press the GO button to feed the paper.
	Tray 2 (the Paper Cassette) is empty.	Add paper to the tray.
	A data error has occurred.	Press the GO button to continue printing (some data may be lost).
	A SIMM error has occurred.	Make sure your SIMM is installed correctly. Replace the SIMM that caused the error. Or press the GO button on the printer to continue without configuring the SIMM that caused the error. If the SIMM has more than one bank of memory, the good banks will be automatically configured.
	A recoverable error has occurred.	Remove the paper jam. Close the top cover. Install a toner cartridge.
	A fatal error has occurred.	Turn the printer off and then back on. If the same light pattern reappears, turn the printer off again and leave it off for about 10 minutes, then turn it back on. If the same light pattern reappears, simultaneously press the GO and RESET buttons on the printer to display a secondary light pattern. This secondary light pattern, or data error light pattern, will more precisely describe the problem.
20 MEMORY OVERFLOW	Too much data, or data too complex.	Press GO to resume printing. Turn Page Protection ON or to AUTO (can be set within the Remote Control Panel). Add optional memory. Reduce the complexity of the print job.
21 PRINT OVERRUN	Too much data, or data too complex.	Press GO to resume printing. Turn Page Protection ON or to AUTO (can be set within the Remote Control Panel). Add optional memory. Reduce the complexity of the print job.
22 IO ERROR	The computer and printer are not communicating because of improper signal protocols. Indicates a loose cable connection or a bad or poor quality cable.	Reseat the cable and make sure you are using a high-quality cable
40 ERROR	Indicates an abnormal connection break occurred while transferring data from the computer.	Press GO on the printer to clear the error message.
41 ERROR	A temporary error occurred while printing. This error most commonly occurs when the printer picks two sheets of paper at once. The page containing the error is reprinted automatically. (first two light sequences)	Remove the page from the output tray and press GO on the printer.
51/52 ERROR	(first and second light sequence) The printer detected a temporary error condition.	Turn the printer off then on. If the problem persists the laser scanner assembly will need to be replaced.
55 ERROR	The printer detected a temporary error condition.	Turn the printer off then back on. If problem persists, the DC Controller will need to be replaced. If the problem still continues, the formatter PCA will need to be replaced.
68 SERVICE or 68 READY/SERVICE	The printer’s nonvolatile memory (NVRAM) is full.	Press GO on the printer to clear the error message. If problem persists, perform NVRAM Reset to clear NVRAM. Hold down the RESET button for more than 20 seconds during power on. If problem persists, the formatter PCA needs to be replaced.
