07C Bypass Tray RAP
Use this RAP to identify and correct problems when using the bypass tray.
Initial Actions
• Check the condition of the media used in the bypass tray. Refer to IQ1 and GP 20.
• Check that the width sensor guide is up to the edge of the paper, Figure 1.
• 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, PL 7.30 Item 1.
Procedure
Enter dC330 code 07-335 to bypass tray empty sensor Q07-335. Press Start. Manually actuate
the sensor. The display changes.

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, PL 7.30 Item 7.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL
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.

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, PL 7.30 Item 1.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL
1.10 Item 2.
Enter dC330 code 08-050 feed solenoid, SOL08-050. Press Start. The solenoid energized.

Go to Flag 3. Check SOL08-050. Refer to:
• GP 12 How to Check a Solenoid or Clutch.
• P/J10, IOT PWB.
• 01G +24 V Distribution RAP.
• 01B 0V Distribution RAP.
Install new components as necessary.
• Feed solenoid, PL 7.30 Item 4.
• Perform OF7 IOT PWB Diagnostics RAP before a new IOT PWB is installed, PL
1.10 Item 2.
Perform the following:
• Ensure that the customer is not filling the tray above the max fill line.
• Clean the feed roll and retard pad with a cloth dampened with water.
• If necessary install a new feed roll and retard pad assembly, PL 7.30 Item 21.
