3.3.08 Forms Tear Off

NOTE:

Tear is activated by pressing TEAR. It is a manual procedure.

FORMS TEAR OFF is activated by changing a setting in the Menu. It is an automatic procedure.

General Information

This feature allows a printed page (rear or bottom feed, continuous form) to be torn off without wasting paper or adjusting the printer.

Forms Tear Off automatically advances the paper from the initial printing position to the tear off position. The top of the page (perforation) will be even with the tear bar. The tear bar is located under the clear top of the access cover.

Paper will remain in the tear off position until the printer receives data. Then, the paper is retracted to the initial print position.

When printing stops, the paper will advance to the tear off position.

NOTE:

If the software package being used "pauses" while sending data to the printer, Forms Tear Off may be activated (if it is enabled through the Menu). The pause must be for two or more seconds. No data is lost. Uneven print registration will occur due to the paper movement. If the problem occurs, deactivate Forms Tear Off through the Menu.

DO NOT use Forms Tear Off with labels or multi-part forms.

Remember to activate the Form Tear Off for the paper path you are using (rear feed or bottom feed).

Vertical Line Spacing Problems

NOTE:

This information is also covered in Technical Service Bulletin 1704.

Customers may experience problems with vertical line spacing when printing on continuous forms and using Forms Tear Off. The first page may not line up correctly. Following pages will not align. The customers may have worked with other Okidata printers and DID NOT experience the problem with the other printer(s). The difference is that the Microline 520 and Microline 521 printers DO NOT have a bail arm. The paper does not feed as "high" as it would in a printer with a bail arm.

If you are experiencing problems with vertical line spacing when printing on continuous forms and using Forms Tear Off, perform the following steps to set the Top of Form position.

1.Enter Menu Mode.

2.Disable Form Tear Off.

3.Exit Menu Mode.

4.Deselect the printer.

5.Use the Micro Feed buttons to set the Top of Form.
