1. Make sure "Adj: Head LR Adj." appears on the LCD, and press Enter.
2. Load paper if not already loaded and press Enter.
3. All the patterns print, and "Gap, 200, N: xxx" appears on the LCD.

4. Check the alignment of the lines on the printed test pattern.
If all the lines are correctly lined up as in the above sample, press
SelecType or Item until "Gap End" appears on the LCD, and then
press Enter to finish.
NOTE: “Gap End” may appear as the following string of garbled
characters: “Gap ïüñ
∝
ßñ: 0”
If some lines are not aligned, select the numbered pattern using the
SelecType or Item button and then press Enter. Then use the Paper
Feed +/- buttons to correct the pattern. Press Enter to print another test
pattern using the setting you just made.
5. Repeat the steps until all numbered patterns are aligned.
