5.2.3.7 Feed Correction + T&B Adjustment
For paper transport, correct the distance and adjust the top & bottom margins and side
margin (printing start position). (See page 241)
Feed Adjustment (Paper feed distance compensation):
Make the printer print a line in the paper feed direction, input the distance and
determine the PF encoder resolution inside the firmware.
The reference length for this determination has been set to 1 m.
(Only the input of a compensation value without printing is possible.)
The input value, handled as the compensation value, is written in the Flash ROM.
Resolution: 0.1mm
Adj Top & Bottom:
Conduct printing and paper cutting and input the distances between the Front
Sensor and the Head, between the Cutter and the Head and between the Edge
Sensor and the Head (writing start position).
The input value, handled as the compensation value, is written in the Flash ROM.
Resolution: 0.1mm
Side Margin Adjustment (Print Start Position Adjustment):
Conduct printing and paper cutting, then measure and input the side margin.
The input value, handled as the compensation value, is written in the Flash ROM.
Adjustment resolution: 0.1mm
Menu transition is shown at right and adjustment patterns are shown on the next page.
Press the [Pause] key on the compensation value input screen, and the display
will change to "Feed Adj.+T&B".
Press the [Pause] key on the "Top Length" or "Bottom Length" input screen,
and the display will change to the "Bottom Length" or "Side Margin" input
