Status Indicator RAPs
10-120, 10-121, 10-126 IOT Exit Sensor RAP
10-120 The lead edge of the paper failed to reach the IOT exit sensor within the correct time
after the trail edge at the fuser exit switch for an inverted sheet.
10-121 The lead edge of the paper failed to reach the IOT exit sensor within the correct time
after the trail edge at the fuser exit switch for an non inverted sheet.
10-126 The trail edge of the paper failed to clear the IOT exit sensor within the correct time.
Initial Actions
WARNING
Ensure that the electricity to the machine is switched off while performing tasks that do
not need electricity. Refer to
GP 14 . Disconnect the power cord. Electricity can cause
death or injury. Moving parts can cause injury.
WARNING
Do not touch the fuser while it is hot.
WARNING
Take care during this procedure. Motors will become hot during normal operation.
• Check the condition of the paper in all trays. Refer to IQ1 and GP 20 .
NOTE: If the fault occurs only with heavy weight paper of 120gsm (32 lb.) or greater that
are being inverted. Then Enter the Tools Mode and Stock Settings. Change the stock type
to heavyweight for the respective tray. If the problem persists, perform the RAP.
• If the faults occur when feeding transparency, install TAG 004 inverter transparency feed
kit.
• If the fault is 10-120 and the paper is fed from tray 1 or tray 2. Check if the paper has
excessive curl and is causing the paper to be skewed when fed from the tray. Install
TAG
002 on the paper tray to constrain the effect of the curl.
• If the fault is 10-120 and the paper is skewed with up-curl ensure a W/ TAG 114 short
paper path assembly is installed.
• Check for obstructions in the inverter area, (35-55 ppm) Figure 1 , (65-90 ppm) Figure 2 .
• Check the upper and lower gravity fingers in the inverter, Figure 3 , GP 7 .
• If the paper has dog ear on the inboard corner, install TAG 005 Rear gravity gate mylar kit.
• Check for obstructions in the exit area.
• Check that the output device is parallel to the machine. Refer to the appropriate adjust-
ment:
– ADJ 11.2-110 Machine to 2K LCSS Alignment.
– ADJ 11.1-171 Machine to HVF/HVF BM, HVF BM to Tri-folder Alignment.
• 35-55 ppm Only. For 10-126 faults. If the machine has a OCT, make sure that the OCT
fingers are installed correctly. Refer to
REP 12.1 .
• For 10-126 faults. If the paper jam is at the entrance to the output device. Go to the rele-
vant output device copy damage RAP:
– 11G-120 Copy Damage in the 1K LCSS RAP.
– 11H-110 Copy Damage in the 2K LCSS RAP.
– 11E-171 Copy Damage in the HVF BM RAP.
• For 10-126 faults. If the paper jam is at the entrance to the output device and the output
device fails to initialize after the front door is closed. Go to the relevant output device ini-
tialization RAP.
– 11B-120 1K LCSS Initialization Failure RAP.
– 11C-110 2K LCSS Initialization Failure RAP.
– 11K-171 HVF Initialization Failure RAP.
• If the fault is caused by a multifeed of sheets, go to the OF8 Multifeed RAP.
Procedure
NOTE: Ensure that the door interlock switch is cheated when ch24V components.
