Changing Media Width - Summa DC4 User Manual

User's Manual DC4

1.6.2 CHANGING MEDIA WIDTH

The DC4 has three positions for the right pinch roller. The recommended roll widths
are: 61, 76, 137cm (24, 30, 54 inch).
The printer remembers always the last loaded media width (even when machine is
switched off) regardless of the chosen user. If a different size of media is loaded,
then the DC4 will prompt the user to check the right pinch roller position (MEDIA
SIZE CHANGED CHECK RIGHT PINCH ROLLER POSITION). Press to
continue and change pinch roller position if necessary.
The line feed calibration (see section 2.2.2.10) depends on the loaded media width.
The line feed parameters are stored per user and it always indicated with a letter in
the upper right corner of the LCD for which media width the current user is calibrated.
(L for 137cm - 54inch; M for 76cm - 30inch; s for 61cm – 24inch.
If a job is sent to the DC4 and the loaded media width is not calibrated with the
correct line feed, then the DC prompts the user with the message: WARNING:
USER IS NOT CALIBRATED FOR THIS MEDIAWIDTH.
Pressing continue will clear this remarks and the DC4 will continue printing, however
it is recommended to quit the job and either calibrate this user with the correct line
feed test for the loaded media or to change to a user wit the correct settings for the
loaded media.
It is recommended to calibrate certain users for specifics widths of vinyl and to
change user when media width is changed. Not changing user when changing media
width will finally result in wrongly calibrated users and bad print quality.
When calibrating a certain user for a specific width, then do the print and cut
calibration (see 2.2.2.11) right after the line feed calibration. This calibration is also
depended of the loaded media width.
