Media Jam Transfer (Image Transfer Section - MINOLTA-QMS Magicolor 2200 Series Manual

3-4 Media jam transfer (image transfer section)

Problem
The paper is stopped at
the timing roller sec-
tion.
The leading edge of the
paper is stopped at the
fusing roller section.
The paper wraps
around the image
transfer belt.
There is no paper any-
where.
Others
A discrepancy is detected when the presence or absence of paper in the paper transport path, by receiving the H/L signals
from the timing roller paper sensor (PC5), transport paper sensor (PC20), and paper exit sensor (PC8). Paper jams for
paper passing through are performed by monitoring the PC5, PC20, and PC8 signals.
• When the timing roller paper sensor (PC5) does not go off within the specified time from the start of turning of the
timing roller.
•
• When the transport paper sensor (PC20) does not go on within the specified time from the start of turning of the tim-
ing roller.
The transport paper sensor (PC20) does not operate when OHP transparency film is being used.
Check
Is the timing rolling contami-
nated with paper dust or other
particles?
Is the tab on the one-way clutch
for the transport roller worn?
Is it a thin paper within the range
of specifications for the paper?
Is the transport paper sensor
(PC20) properly detecting
paper?
