Original Size Detection – Platen Mode (2)
This table shows the outputs of the sensors for each original
size.
Slide 26
The above table shows the outputs of the sensors for each original size. This original
size detection method eliminates the necessity for a pre-scan and increases the
machine's productivity.
For other combinations, "Cannot Detect Original Size" will be indicated on the operation
panel display (if SP 4303 is kept at the default setting). However, if the by-pass feeder is
used, note that the machine assumes that the copy paper is short-edge first. For
example, if A4 paper is placed long-edge first on the by-pass tray, the machine assumes
it is A3 paper and scans the full A3 area for the first copy of each page of the original,
disregarding the original size sensors. However, for each page, the data signal to the
laser diode is stopped to match the copy paper length detected by the registration
sensor. This means that copy time for the first page may be slower (because of the
longer time required for scanning), but it will be normal for the rest of the job.
