Cause What to do

The lines-per-page, top and bottom margin, or form length setting is incorrect.

Adjust these settings in your application software, as follows:

If your application software has a lines-per-page setting, set it to 66 for letter size paper or 70 for A4 size paper. If your software does not have a lines-per-page setting, try decreasing the top margin or increasing the bottom margin, or both, until you get the results you want. Adjust the form length setting if your software has this option.

Vertical printed lines are not aligned.
Cause What to do

Bidirectional printing, which is the printer's standard printing mode, may be out of alignment.

Use the printer's bidirectional adjustment mode to correct this problem. See Aligning Vertical Lines in Your Printout.
