TESTFEED

Field of Application

Statement for adjusting the label stop sensor while performing a

number of formfeeds.

Syntax TESTFEED[<nexp>]

<nexp> is an optional feed length in dots.

Remarks

The TESTFEED statement feeds <nexp> dots while adjusting the label

stop/black mark sensor (LSS) for the characteristics of the media presently

loaded in the printer. The adjustment is needed to detect media, gaps,

black marks, and out-of-paper conditions, therefore is must be done

for all media types.

If <nexp> is omitted, <nexp> is automatically set to 1.5 times the

media length speciﬁ ed in the setup. For the TESTFEED operation to

be successful, at least one gap or black mark must pass the LSS. Also

see SYSVAR(38).

In the Immediate Mode, a TESTFEED is performed when the <Shift> and

<Feed> keys are pressed simultaneously.

Since the TESTFEED is essential for a proper media load, some facility

for issuing a TESTFEED statement should be included in all custom-made

label-printing programs (see the example below).

Example

This program performs a TESTFEED statement when the <Shift>

and <Feed> key are pressed simultaneously on the printer’s built-in

keyboard:

10 ON KEY (119) GOSUB QTESTFEED

20 KEY (119) ON

30 QLOOP:

40 GOTO QLOOP

. . . . .

1000 QTESTFEED:

1010 TESTFEED

1020 RETURN
