Sub Scan Reduction Enabled
When Sub Scan Reduction is enabled, the received fax image is reduced in
the page memory to fit on the selected paper, if the received image length is
between [paper length - 4 mm] and [paper length + 20 mm]. See the drawing
below.
Note
The upper limit (page length + 20 mm) is adjustable between 0
and 155 mm. Refer to Printer Switch 04, bits 0 to 4 for more
details.
If the FCU detects that the image must be separated into more than one
page after reduction, what happens to the data depends on the Reduction
Rate Equalization setting (Printer Switch 0E, bit 7).
- Reduction Rate Equalization Off (Example Diagram: Two-page Printout) -
1. The data up to [page length - 4 mm] will be printed on page 1, without
reduction.
2. The last 10 mm of this data will be repeated at the top of the next page
(this length can be can be adjusted or repetition can be switched off).
3. The remaining data will be printed on page 2, with reduction, if it is within
[paper length + 20 mm].
4. If it is longer than this, page separation is done again. Data up to [page
length - 4 mm] will be printed on page 2, without reduction.
5. The process for page 3 and subsequent pages will repeat from step 2.
