Report FW Version Reports current firmware version.
Report Status Reports the current Scanner Assembly status:
• OK- (no errors detected)
• Internal Target Failure
• Optical Test Error
• Home Position Test Error
• Check Lock Test Error
Report Lamp Status The Scanner reports the current lamp status as On, Off, or Warming
Up. The Warming Up status includes the dim state, which won't
change to On until instructed to do so.
Monitor Sensors This monitors the state of the Scanner Cover (DADF or Document
Cover) Sensor. Toggle the sensor state by opening the cover.
Exercise DRAM The Scanner performs a DRAM test. Errors are reported as a Internal
Target Failure and the lamp flashes twice.
Exercise Axis Motion The Scanner moves the scan axis to the Home position, then to the
right limit of travel, and then back to the Home position. This test exer-
cises the axis motion mechanism and the Home sensor.
Exercise Axis
Unlocked
The Scanner performs a Locked test. Errors are reported as Check
Lock Test Error. The test determines if the scanner motion axis is cur-
rently unlocked and available for use.
Exercise Data Cap-
ture
The Scanner performs a Data Capture test which exercises the lamp,
optics, CCD, DRAM, and supporting electronics. Errors are reported
as an Optical Device Error. For this test the lamp is on and the scan
head is moved under the calibration strip.
Exercise Lamp The Scanner turns the lamp On, Off, then On. Each state is held for a
short time to allow observation of the lamp state. Errors with a light
state transition are reported as a Light Check Error. The lamp may be
On prior to the test, and the lamp is left On after the test. Each lamp
On transition triggers a calibration function which takes approximately
50 seconds to complete. The test exercises the lamp and the lamp
control.
Test Scanner Sub-
system
The Scanner runs a series of tests to verify the operation of these
Scanner functions as previously described:
• DRAM
• Unlock
•Motion
• Capture
• Lamp
Reset Scanner Sub-
system
This test forces a hardware reset of the Exit Module, Scanner, DADF
and FAX modules.

Report FW Version Reports the current DADF firmware version.
Report Status Reports the current DADF module status:
• OK - (no errors detected)
• Paper Jam
• Cover Open
• Internal Target Failure
•Test Fail
• Optical Test Error
• Calibration Device Error
Report Lamp Status The DADF reports the current lamp status as On, Off, or Warming Up.
The Warming Up status includes the dim state, which won't change to
On until instructed to do so.
Report Paper Status The DADF reports the current status as Paper or No Paper.
Monitor Sensors Tests the DADF No Paper and Cover Sensors. Toggle the actuator to
change sensor state. Results are reported as Paper Present or Not
Present, and Cover Open or Closed.
Exercise DRAM The DADF performs a DRAM test. Errors are reported as a Internal
Target Failure and the lamp flashes twice.
Exercise Data Cap-
ture
The DADF performs a Data Capture test which exercises the lamp,
optics, CCD, DRAM, and supporting electronics. Errors are reported
as an Optical Device Error. For this test the lamp is on and the scan
head is moved under the calibration strip.
Test Cal Sheet Motion The DADF performs a Calibration Motion test which moves the cal
sheet out under the lamp. Errors are reported as a Calibration Device
Error. The test determines if the cal sheet motion is as expected.
Exercise Feed Motion The DADH performs a Transmission test. This test rotates the trans-
port rollers for a short time (sufficient to transport a 14 inch sheet of
paper). The test requires observation of the correct action, and a final
status of Complete is always reported. Remove all media from the
DADF before running this test.
Exercise Lamp The DADF turns the lamp On, Off, then On. Each state is held for a
short time to allow observation of the lamp state. Errors with a light
state transition are reported as a Light Check Error. The lamp may be
On prior to the test, and the lamp is left On after the test. Each lamp
On transition triggers a calibration function which takes approximately
50 seconds to complete. The test exercises the lamp and the lamp
control.
