Press the ; key. "DIAGNOSTICS" displays. 9. Press >. "DIAGNOSTICS / Printer Tests" displays. 10. Press >. "SHIFT / RECYCLE" displays. 11. Press < until "Paper Out Adjustment" displays. This test will print a vertical "comb" pattern at around column 70, each long bar separated by three shorter bars. An enlarged example of the comb pattern is shown below. Note 12. Press ENTER until the Paper Out Adjustment test starts. The comb pattern will print until the display shows "LOAD PAPER" and the audible alarm sounds. 13. Open the platen and move the paper up with the vertical position knob and examine the area of the page perforation. If a long bar just meets the perforation, the paper out adjustment distance is correct, skip to step 26. (1 or 2 dot rows above the perforation is OK; 5 to 7 dot rows above or any dots below the perforation mean adjustment of the Paper Out Dots value is required.) If the comb pattern stopped short of the perforation or printed beyond the perforation, go to step 14. 14. Measure how short or long the comb pattern printed by counting the number of dot rows needed to reach the perforation, or the number of dot rows that printed beyond the perforation. You can use the long bars to count the dot rows quickly. There are three dot rows between each long bar, so each long bar increases the number of dot rows by four. You can also tear off a small piece of the comb pattern from the beginning of the pattern and use it as a ruler to help you measure the dot rows required either to reach the perforation or back up to it. 15. Close the platen. 16. Press CLEAR to remove the fault condition. "OFFLINE / CONFIG. CONTROL" displays. 17. Press the ; key. "DIAGNOSTICS" displays. 18. Press >.

is correct, skip to step 26. (1 or 2 dot rows above the perforation is OK; 5
to 7 dot rows above or any dots below the perforation mean adjustment of
the Paper Out Dots value is required.)
If the comb pattern stopped short of the perforation or printed beyond the
perforation, go to step 14.
