the valley as shown in the “good position” of Figure 13. If the cam is positioned properly, go to “Cross-hatch Pattern Test,” on page 14. If the cam is not positioned properly, go to step 5. Figure 13 2. If the cam position looks like one of the two positions “bad positions” in Figure 13, go to “Print Head Cam Adjustment,” on page 12. Once the cam is adjusted properly, go to “Cross-hatch Pattern Test,” on page 14.

The drawer must be in the out position when making this adjustment. If the drawer is not open, run test one. 1. If the printer is not in “Diagnostic Mode,” power on the printer while holding down the Unit attention button for at least eight seconds. 2. Press the Unit attention button five times to run test five. When you press the button for the fifth time, hold the button down until the print head moves. See Figure 14. Figure 14 1. Press the Unit Attention button four times to run test four. This will raise the print head to make sure the cam is in the correct position as shown in Figure 13. 2. If the cam is in the correct position, go to “Cross Hatch Pattern Test” on page 14. If the cam is not in the correct position, go to step 5.

Figure 15. Figure 15 2. Adjust the plate as required using tests four and five to move the cam. If the cam position looks like #1 in Figure 13, you need move the cam upwards. This is done by adjusting the opto plate downward 1/32 of an inch. If the cam position looks like #2 in Figure 13, you need to move the cam downwards. This is done by adjusting the opto plate upward 1/32 of an inch. 3. Tighten the Torx screw when the roller bearing stops at the valley point. Go to the “Cross-hatch Pattern Test” on page 14.
