PPR ALIGN CHK
When you select ON, if the paper is not straight, PAPER NOT
STRAIGHT is displayed on the LCD and the printer stops printing.
When you select OFF, a paper align error does not occur even if
the printed data is out of range of the paper and the printer
continues to print.
TIME OUT
The setting range is 30 to 300 seconds. If a cable of your printer
unplugged or your printer hangs up for more than the set time
range, the print job is cancelled and the printer starts paper feed.
CUTTER ADJ
You can adjust the paper cutting position when printing with a
top and bottom margin of zero. This function prints cutter
adjustment patterns and you can select the appropriate cutting
position from among them.
REFRESH MRGN
When you select ON, the printer cuts extra print area after
borderless printing is used automatically.
SHEET SIZE CK
When you select ON, if the size of the cut sheet loaded in the printer
does not match the size of data, the printer stops printing and
WRONG PAPER SIZE appears on the printer's control panel. When
OFF is selected, the printer continues to print even if the size of cut
sheet does not match the data and the printer may print off of the
paper.
AUTO NZL CK
When you select ON, the printer performs a nozzle check before
printing, for each print job.
