improperly.

1. Turn OFF both power switches.

2. Remove the fixing unit.

3. Observe the position of the ADU change solenoid arm (p/n 26NA-4870).

4. The arm (white plastic) should not be positioned behind the arm (black plastic) of the paper
exit guide (p/n 26NA48250).

SYMPTOM :J20-4 occurs only when making copies in the 1:2 or 2:2 mode.

RESOLUTION: CAUSE: The jumper for the copy vendor connection is loose. When the

ADU gate solenoid (SD5) actuated, the vibration caused the copy vendor connection to
open signifying a stop signal.

SOLUTION: Reform the jumper on the copy vendor to allow proper contact with the
connector.

SYMPTOM : F28-4 after installing a drum.

RESOLUTION: CAUSE: The toner control sensor board is covered with setting powder.

SOLUTION: Clean the toner control sensor board (p/n 26NA-9180) with a blower
brush. Do not

use an excessive amount of setting powder.

SYMPTOM : SUPPLY TONER message occurs when toner bottle is full or has just
been replaced.

RESOLUTION: PROBABLE CAUSES:

1. The toner bottle is not fully seated into its holder. Push the bottom of the toner
bottle to see if it clicks. The toner bottle is correctly set when it clicks twice on its
insertion. If the toner does click, rotate the bottle clockwise 10 times to manually
add toner to the machine. Note: It is normal to hear some gear noise as the toner
bottle is rotated. This will not harm the machine.

2. If the toner bottle is stored for a longer period of time with its opening downwards,
toner may compact at the edge of the opening. This can prevent the bottle from
properly supplying toner when the bottle is rotated. When installing a new toner
bottle, ensure the toner moves freely by performing the following:

a. Without removing the cap, tap the bottom of the bottle 5 times on a solid

surface from 5- 6cm distance.

b. Turn the bottle upside-down and tap the top 5 times on a solid surface from 5-

6cm distance.

c. Shake the bottle horizontally 5 times.

SYMPTOM : With the Auto Start feature enabled, every time the platen cover is
lifted, a copy is made whether a document is on the platen glass or not.

RESOLUTION: Platen APS is not enabled in the Key Operator Mode. This allows the

auto start copy feature to scan with no document on the glass.

SOLUTION: To enable Platen APS, perform the following:

1. Enter the Key Operator Mode by pressing the HELP key and then pressing KEY-

OPE MODE on the LCD in lower left-hand corner.

2. Press SYSTEM/COPIER.

3. Press 12. MEMORY SWITCH.

4. Use the arrows on the right hand side to scroll to PLATEN APS.

5. Press EDIT to change to ON.

6. Press RETURN until the copy screen is seen.

SYMPTOM : "FAILED TO ADJUST" error message appears after attempting to
adjust the scanner of the RADF.

RESOLUTION: PROBABLE CAUSES:

1. Copy paper was used instead of the white chart enclosed with the machine. Use the
enclosed white chart when performing the scanner adjustment.

2. The white chart is soiled. Replace the white chart.

3. The white chart was set in the A4R direction when the adjustment was performed.
Set the white chart in the A4 direction and then readjust.

4. Height of the ADF is not adjusted. Complete the ADF height adjustment outlined in
the 7040 Service Manual.

5. Platen glass is soiled. Clean the platen glass.

6. The exposure lamp is soiled, deteriorated, or incorrectly installed. Clean, replace
and/or verify correct installation of exposure lamp.

window are greyed out after copying the files.

RESOLUTION: CAUSE: One or more control files are missing in the ISW Trans

SOLUTION: Verify that all correct files are in the "SendFile Info"Window. Verify all
the files are in the source folder or on five floppy disks before using the copy utility in
the ISW Trns utility. Copy the missing files into the correct folder.
