HP 6L pro, 6L Gold manual Unclearable error, Sleep Mode

Table 7-1 Printer status messages (Continued) (Sheet 2 of 2)

LEDs

Description	Recommended action
Sleep Mode.	If the printer’s LEDs remain off:
	1.	The printer is in Sleep Mode. Press the
	Control Panel Button or open the EP Door.
	2.	Power is not supplied to the printer. Check
	power cord connections and the power source.
	3.	Print an engine test to determine if the print
	engine is functional. If the test is successful,
	replace the Formatter PCA.
	4.	See the General Troubleshooting Flowchart
	earlier in this chapter.

	Occasionally you may add paper, close the printer door, add the toner cartridge, and clear a paper
	jam, only to find that the printer still displays an error message. If this happens, troubleshoot using
	Table 7-3 below.
Note	If the error appears and persists only after you attempt to print a page, verify that the motor is
	functioning. (See “Printing an Engine Test” later in this chapter.)
	Table 7-2 Unclearable error
		This error will persist if any of the three paper movement photosensors (PS201,
		PS202, and PS203) and/or their flags are not functional.
		1. Verify that all three photosensor flags are not blocked and move freely. (See Figure
		7-1 to identify photosensor flag locations.)

l Paper Out Flag (PS202) (See Figure 5-6.)

lPaper Registration Flag (PS203) (See Figure 5-6.)

lExit Sensor Flag (PS201) (See Figure 6-18.)

2.Verify that all connectors are firmly seated. (See Figure 7-2 to identify connector locations on the DC controller.)

lDoor closed/EP Cartridge Photosensor connector (5L only)

lPaper-Out and Registration Photosensor Connector (See Figure 5-6.)

Note: There is no connector for the Exit Photosensor (PS201) since it is located on the DC Controller PCA. This flag is located beneath the Fusing Assembly. (Refer to Figure 6-18.)

If all of the flags move freely and all of the connectors are correctly seated, yet the error persists, replace the DC Controller PCA.
