Tally Genicom 2900 manual After unlocking the Print Gap keys, Set Print Gap Detect Mode to Manual

Print Gap

After unlocking the Print Gap keys:

Press one of the Print Gap keys on the Control Panel. This activates the Print Gap adjustment display. Look at the Control Panel. The upper right region of the LCD shows a number 1 corresponding to the optimal print gap determined by the detection process. The lower right region displays a “fine tuning” offset which is added to the detected print gap to set the actual gap number. Initially the “fine tuning” offset is 0, but it can be made negative or positive to adjust the

print gap smaller or larger, respectively, by pressing the corresponding “-” or “+” Print Gap key on the control panel. The offset range is limited by the printer. The lower left region of the LCD provides a graphical indication of the adjustment being made. There is a 5 second time-out: if no keys are pressed the control panel display will revert to the prior menu and display. Fine-tuning the print gap in this way may be done while printing is in progress, allowing the operator to modify the gap and immediately observe the effect it has upon print appearance.

See Chapter 3 for the specifics of the Print Gap menu.

Step 1. Manually Adjust Print Gap on Control Panel

Press one of the Print Gap keys on the Control Panel. This activates the Print Gap adjustment display. The lower right region of the LCD shows a number1 corresponding to the current gap separating the hammer impactors from the platen. Press the "+" or "-" Print Gap key to roughly match the setting to the kind of paper that is loaded. This number will get larger or smaller respectively. The range of allowed change is unrestricted over the complete gap range.2 Typical values range from 54 to 110 for single-part through six-part forms.

displayed number and physical distance is complex and beyond the scope of this manual.

2.The control software will prevent selection of a print gap so small that it would pinch the paper so tightly that it will bind within the mechanism.
