Original Size Detection – SP Modes
5126: Determines which F size is detected
6016: Determines how the machine interprets
width/length sensor output for paper sizes that
are almost the same.
Slide 268
Make sure that the class is familiar with the table of sensor output vs original
size.
SP 5126
Use SP 5126 to control the size that is detected for the 'F' sizes, which are
very similar (8½ x" 13", 8¼" x 13", 8" x 13"), and cannot be distinguished by
the sensors.
SP 6016
There are 7 bits. Each bit represents two paper sizes that are almost the
same. Select 0 or 1 to decide which paper size the machine detects from that
pair.
