❏ Paper alignment
Current print line location
The current printing line (DDD...) is the third line down from the top of the ribbon guide (line
spacing is 1/6 line: 6 LPI).
Adjusting the print head position
The head adjustment is used to obtain the best print quality possible for the specific paper
being used. The print head position can be adjusted to accommodate printing on single and
multipart forms. When using multipart forms, move the print head adjustment lever toward the
front of the printer to widen the gap between the print head and the platen.
In general, position 1 is used for one-part paper. Moving the head adjustment lever one notch
adjusts the print head gap an amount corresponding to the addition of one more paper part.
Re-adjustment of the lever may be required depending on the quality of the actual printout:
• If the ribbon smears on the paper, the gap is too narrow.
• If the printed image is too light to read, the gap is too wide.

Notes
1. The print head adjustment lever should be set before loading the paper to avoid paper
jams.
2. If the printed image on the last copy of a multipart form is too light to read, set the
MULTIPART mode in the basic setup options (see page 26). This will increase the
striking intensity on multipart forms.
