Action
If the paper does not feed, do the following:
• Remove the ASF.
• Be sure the base printer feeds paper
correctly.
• If it does not feed paper correctly, go to
the "Paper Feed Service Check" on page
2-27.
Be sure the ASF drive gear on the inside of the
printer's right frame rotates.
Inspect the right side gear train for damage or
debris.
Remove the ASF right cover and ensure that
all gears are in good condition.
Install the ASF and press Form Feed.
If the picker drive shaft does not rotate, replace
the combination lock mechanism.
If the ASF picker rollers rotate but a single
sheet is not picked, inspect the springs and
corner separators on the left and right hoppers.
Make sure the paper load lever is in the correct
position.
