Why each option
When replacing an impact printer print head, the platen gap - the distance between the print head and the platen - must be carefully adjusted to ensure proper print quality and prevent mechanical damage.
The ribbon drive assembly does not require adjustment when replacing the print head - it operates independently of print head positioning.
Form thickness is a user-level setting for paper types and does not require mechanical adjustment when swapping the print head.
The platen gap is the precise space between the print head pins and the platen (the roller or flat surface that holds the paper). If this gap is too narrow, the print head can jam or be damaged; if too wide, the pins will not strike the ribbon with enough force to produce legible print. Adjusting this gap is the critical mechanical step when installing a new print head.
Form length is a software or control panel configuration for page length and is not affected by print head replacement.
