Adjustments
TNormally, 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 stepping motor will have a heavy load or 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.
In addition, adjustments will be useful for avoiding wrinkling of the ribbon or skewing of the paper. For more information, contact our service personnel.
