3.5 Media Width Adjustments
CAUTION Ensure the print head adjustments are made correctly according to the type of media (thickness & width). Incorrect adjustments can cause failure of the print head.
Adjustments may be needed if paper with different width is used. Print darkness is affected by the amount of pressure on the print head so it must be adjusted with the head pressure adjustment screw if necessary.
The pressure on the right side of the print head, viewed from the front panel, is adjusted by turning the head pressure adjustment screw. Turning the screw clockwise decreases the pressure, and turning the screw counterclockwise increases the pressure.
Normally, the pressure on the left and right sides of the print head has already been adjusted to equal loads at the factory. The check marks are located under the upper frame window.
Adjustments are needed in the following cases:
1)When print on the left side is too light, turn the head pressure adjustment screw clockwise.
2)When print on the right side is too light, turn the head pressure adjustment screw counterclockwise.
3)When paper of smaller width is used:
In this case, the contact between the print head and the platen becomes large, so the motor will have a heavy load and the print head may scrape the platen. To avoid this, turn the head pressure adjustment screw clockwise to decrease the pressure on the right side of the print head.
