How You Determine the MACF
In the 'Roll Media Manager' menu you can select the 'Media Advance
Correction Factor' (MACF) and enter a value from 0 to 100. The default
value is 50. You can enter a lower value to correct for white gaps or raise
the value to correct for dark lines.
.
Procedure
1.
Put several instances of the MACF print in the print queue.
2.
Print with a default MACF of 50 (adjusted in Roll Media Manager).
3.
If white lines appear, the media is overstepping. Gradually decrease the
MACF until the white lines start to disappear. Make a note of the MACF
value. Continue to decrease the MACF until dark lines just start to appear,
and note the value. Typically, the average of these two is the ideal MACF
for this media.
4.
Similarly, if dark lines appear lines appear, the media is under-stepping.
Gradually increase the MACF until the dark lines start to disappear. Make a
note of the MACF value. Continue to increase the MACF until white lines
just start to appear, and note the value. Typically, the average of these two
is the ideal MACF for this media.
