Action
Check to make sure the gamma wheel aligner assembly is operating
correctly and that the wheel is touching the paper. If the gamma
wheel is not turning or touching the paper, go to step 2. If the wheel is
turning and touching the paper, check the wheel for wear, damage, or
contamination. If any problem with the wheel is found, replace the
wheel.
Check to make sure the aligner assembly and pads are operating
correctly. Make sure the pads are touching the paper and moving the
paper to the right side frame. If the aligner pads are not moving into
the lower position and touching the paper, go to step 3. If the aligner
pads are touching the paper, make sure the pads are not worn,
damaged, or contaminated. Replace if necessary.
Check the paper wheel aligner assembly to make sure it is mounted
correctly. Check to make sure there are no broken gears or other
mechanical parts. If any are found, replace the aligner assembly. If no
problem is found, go to step 3.
Check to make sure the cable to J4 (Accessory) is properly
connected to J4 on the board. Turn the printer off, disconnect the
motor cable from J4, and check for continuity between J4 pins 1,2,3,
and 4 to the motor case. If you get continuity, replace the gearbox
drive assembly. If you do not get continuity, continue with the step.

If the voltages are correct, replace the gearbox drive assembly. If the
voltages are incorrect, replace the stapler board.
Action
Check the left side bail assembly for any signs of binding, missing, or
broken parts.
Check the stapler gearbox assembly for correct operation.
Action
Disconnect Sol 1 cable from J5 on the stapler card and measure the
resistance of the solenoid across the cable connector. It should
measure approximately 48 ohms (when cold). If incorrect, replace the
stapler/finisher option assembly. If correct, replace the stapler card
assembly.
