5.4.11 Print Skew

Perform this adjustment if the printing is not perpendicular to the left document edge.

1. With power on, insert an 8 1/2" wide document with known good perpendicular edges into the rear

document drive rollers and insure that its left edge is still flush to the edge guide.

2. Print an 80 character line of local printing (see 3.9) and eject.

3. The distance from the top document edge to the bottom of the print line should be the same within .01" (.25

mm) on both ends of the print line. Proceed only if adjustment is necessary.

4. Remove the cabinet (see 5.5.1)

5. Loosen the 2 screws that fasten the right document drive side plate to the right side of the metal box.

6. Move the right side of the document drive further into the box to rotate the print line clockwise. Move it out

of the box to rotate the print line counterclockwise. Do not move it so far that the carriage binds against the

upper exit guide or the ribbon shield support binds against the upper input guide.

7. Tighten the screws and return to step 2.

8. If skew cannot be eliminated by moving the right end of the document drive, move the left end but and then

check the document drive belt tension and top offset (see 5.2 & 5.4.3)
