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.)
LEDs Description Recommended Action
Sleep Mode If the printer’s LEDs remain off:
1. The printer is in Sleep Mode. Press the Front 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.
Table 7-2 Printer Status Messages (Continued 2 of 2)
This error will persist if any of the three paper movement photosensors
(PS201, PS202, PS203, and PS204) 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.)
• Paper Out Flag (PS202) (See Figure 5-6.)
• Paper Registration Flag (PS203) (See Figure 5-6.)
• Exit Sensor Flag (PS201) (See Figure 6-18.)
• Door closed/EP Cartridge Flag (PS204) (See Figure 5-6.)
2. Verify that all connectors are firmly seated. (See Figure 7-2 to identify
connector locations on the DC controller.)
• Door closed/EP Cartridge Photosensor connector
• Paper-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.
