07D Bypass Tray RAP
Use this RAP to identify and correct problems when using the bypass tray.
Initial Actions
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to GP
death or injury. Moving parts can cause injury.
• Check the condition of the media used in the bypass tray. Refer to
• Check that the width guide is touching the edge of the paper,
• If there is a width sensing problem, then check that the bypass tray width sensing potenti-
ometer is not damaged, part of input tray assembly,
Procedure
Enter dC330 code 07-335 to bypass tray empty sensor Q07-335. Press Start. Manually actuate
the sensor. The display changes.
Y N
Go to Flag 2.Check Q07-335. Refer to:
• GP 11 How to Check a Sensor.
• P/J10, IOT PWB.
• 01D +3.3 V Distribution RAP.
• 01B 0V Distribution RAP.
Install new components as necessary.
• Bypass tray empty sensor,
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed,
1.10 Item 2.
Go to Flag 1. Monitor the voltage on the IOT PWB at PJ10 pin 1 and move the guide in and
out. The voltage varies from 0V to +3V.
Y N
Go to Flag 1. Check Q07-350. Refer to:
• The width sensor is a potentiometer. The arm on the potentiometer is attached to the
bypass tray side guide. This gives a variable voltage to indicate the paper width set-
ting.
• P/J10, IOT PWB.
• 01D +3.3 V Distribution RAP.
• 01B 0V Distribution RAP.
Install new components as necessary.
• Bypass tray width sensor, part of input tray assembly,
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed,
1.10 Item 2.
Enter dC330 code 08-050 feed solenoid, SOL08-050. Press Start. The solenoid energized.
Y N
Go to Flag 3. Check SOL08-050. Refer to:
• GP 12 How to Check a Solenoid or Clutch.
