Stream reading will be selected under the fol-
lowing conditions if the RDF is installed to the
copier; in stream reading, the scanner is fixed in
place, and originals are fed from right to left for
exposure:
• A4, LTR, or B5 one-sided original
• one-sided original to 1-sided copying
• reproduction ratio between 86% and 115%
Stream reading allows the omission of the
scanner reversal period, thereby enabling the
generation of 85 copies/min (A4; 83 copies of
LTR).
The RDF feeding speed can be adjusted in
service mode
