CLEANFEED
Field of Application
Statement running the printers feed mechanism.
Syntax CLEANFEED<nexp>
<nexp> is the feed length expressed as a positive or negative
number of dots.
Remarks
The CLEANFEED statement activates the stepper motor that drives the
printers platen roller (the rubber roller beneath the printhead). In case of
thermal transfer printers, it also often drives the ribbon mechanism. The motor
will run regardless of possible error conditions, for example if the printhead is
lifted or not, or if there is no ribbon or media supply left.
Thus, the CLEANFEED statement is suitable for cleaning and for the
loading of transfer ribbon.
A positive CLEANFEED value makes the stepper motor rotate the rollers
forward, that is as when feeding out a label.
A negative CLEANFEED value makes the stepper motor rotate the rollers
backwards, that is as when pulling back a label.
The execution of a CLEANFEED statement, as opposed to TESTFEED,
does not affect the adjustment of the label stop sensor or black mark sensor,
regardless what type of media or other objects that passes the sensor.
Note that the CLEANFEED statement, as opposed to FORMFEED, always
must be speci ed in regard of feed length.
Example
In order to pull a cleaning card back and forth under the printhead three
times, three 1200 dots long positive CLEANFEEDs and then the same
amount of negative CLEANFEEDs are performed:
10 FOR A%=1 TO 3
20 CLEANFEED 1200
30 CLEANFEED -1200
