1.4.1.11 Reverse Paper Feed Protection
Since the ink is still wet just after printing, the paper will be smudged if it is rubbed by something.
In this printer, nothing rubs the paper when it is fed in the forward direction. However, as shown in
Figure 1-22, the paper touches the paper guide plate when it is fed in the reverse direction.
Therefore, reverse paper feeding is prohibited by the software (soft protect operation) to prevent the
paper from being smudged. The soft protect operates as follows:
•
Cut Sheets
If reverse paper feeding is executed by pressing the MICRO FEED switch after printing, the paper
will only be fed until the line printed last reaches the paper guide plate position. (The platen will
not rotate in the reverse direction any farther.)
•
Fan-fold paper
If reverse paper feeding is executed by pressing the MICRO FEED switch after printing, the paper
will only be fed until the line printed last reaches the paper guide plate position. (The platen will
not rotate in the reverse direction any farther.)
If an eject (back out) operation is attempted just after printing, it will be ignored, and the following
message will be displayed on the LCD.
I
PLEASE TEAR OFF
The paper cannot be ejected unless the paper is cut off by pressing the TEAR OFF switch.
•
CSF
When printing is executed with the CSF mounted, reverse paper feeding cannot be executed at all.
