2.1.12 Timing chart
The conditions in effect for the chart below are as
follows:
• A4 size paper
• 2 continuous copies
• Paper feed from tray 1
• Platen cover mode
Pulse conversion is:
1 pulse = 2.34 msec = 1 mm
Description
❈1 In the platen cover mode, pulse counting starts from
when the start key is ON, but in the ADF mode, the
count starts 3.5 sec after ON.
❈2 The paper feed signal is generated from the main

The first paper feed signal after start
key ON varies for each paper feed
station and with paper size to match the
imaging position of the photoconductor
(tray 1 is earlier than 3).
Paper feed signal after
the second feed varies
according to paper
size.
