Fixing the Grid Alignment Issue on the FC1400 Printer
The Fetal Monitor FC1400 is designed with a slightly wider printer compartment to help prevent paper jams.
For proper alignment, make sure to load the paper as far to the left as possible, as shown in the picture below.
Then, go to Main Menu → Printer → Grid, switch the setting from Off to On, and check if the grid lines are correctly aligned with the paper.
