Solve problems Intermediate paper-transfer unit (IPTU) NOTE: This item is called the "output-accessory bridge" in the user documentation for this product. Stapler/stacker and booklet maker Individual component diagnostics Manual sensor test The manual sensor test indicates the status of the sensors in the product. It can verify the current status or the last change in status of the listed sensors. From the DIAGNOSTICS menu, scroll to and touch Read all once to check the current status of the sensors. Each sensor is assigned a letter. The sensor test indicates the status of each sensor with a corresponding "0" for non-activated or "1" for activated. The status message appears on the controlpanel display for 10 seconds. After 10 seconds, the message is cleared and Ready appears on the control-panel display. From the DIAGNOSTICS menu, scroll to and touch Continuous reading to check the last change in status of the sensors. The output device reads the status of the sensors and stores the data. Next, the output device continuously reads the sensors until it detects a change. The change-in-status message appears on the control-panel display indicating which sensor changed from the original reading. Note that the status messages appear on a first-in, first-out basis. If two or more sensors change in a short period of time, only the first change detected is indicated as a status message on the control-panel display. Use the following table to determine which component each letter designates.. Table 8-15 Manual sensor test letter designations Letter Component A Front door 1, PI32 (Front-door sensor) B Front door 2, PI9 (Saddle-guide sensor) C Top door, PI31 (Top-door sensor) D Booklet door 1, PI3 (Booklet-delivery-door sensor) E Booklet door 2, SW3 F Stapler home sensor, P140 (Staple-shift home-position sensor) G Swing unit, PI35 (Swing-guide home-position sensor) H Folding plate, PI13 (Guide home-position sensor) I Process tray assy, PI38 (Processing-tray sensor) J Bin-1 empty, PI42 (Output-bin-1 paper sensor) ENWW Solve problems 739

Individual component diagnostics

Manual sensor test

The manual sensor test indicates the status of the sensors in the product. It can verify the current status

or the last change in status of the listed sensors.

From the

DIAGNOSTICS

menu, scroll to and touch

Read all once

to check the current status of the

sensors. Each sensor is assigned a letter. The sensor test indicates the status of each sensor with a

corresponding “0” for non-activated or “1” for activated. The status message appears on the control-

panel display for 10 seconds. After 10 seconds, the message is cleared and

Ready

appears on the

control-panel display.

From the

DIAGNOSTICS

menu, scroll to and touch

Continuous reading

to check the last change in

status of the sensors. The output device reads the status of the sensors and stores the data. Next, the

output device continuously reads the sensors until it detects a change. The change-in-status message

appears on the control-panel display indicating which sensor changed from the original reading. Note

that the status messages appear on a first-in, first-out basis. If two or more sensors change in a short

period of time, only the first change detected is indicated as a status message on the control-panel

display.

Use the following table to determine which component each letter designates..
