2.3 Enlargement/Reduction

Change
Scanning speed at
100% copying
Enlargement/reduction
according to range
The machine scans originals faster to support its higher speed of printing. Under specific
conditions, it uses a digital method for enlargement/reduction in combination to enable a
higher scanning speed, while keeping the speed of the scanner motor to more or less the
same as that of the GP605 (iR600).
Normally, copying with the ADF in use is in stream reading; however, fixed reading is
used for reduction between 25% and 49.9% and for all ratios in double-sided mode and in
book mode.
The digital method of enlargement/reduction is used for the following:
• for fixed reading, if between 25% and 49.9%
• for stream reading, if between 25% and 84.9%
