Hint

When the paper feed assembly is installed, the sensor-flag spring must be correctly positioned for the flag to operate. If a paper-jam error message (13.20.00 JAM) appears on the control-panel display after you replace the paper feed assembly, verify that this sensor-flag spring is installed correctly.

Hook the spring over the flag tab (see 1 in Figure 153). Fasten the paper feed assembly to the chassis with the flag spring positioned in the hole in the transfer assembly. Release the spring from the tab on the flag (see 2 in Figure 153). See figure 153 below.

Verify that the flag is held in the upright position, can freely move, and always returns to the upright position. If the flag does not move freely, or return to the upright position, an error

message (13.20.00 JAM) will appear on the control-panel display when the printer power is turned on.

Verify that the clutch tab on the right side of the paper feed assembly is inserted into the hole in the plastic frame.

The anti-static bar (see “Cooling fan (right side; HP LaserJet 4300 series printer only)” on page 170) can be used to release the sensor spring.
