Tape'bransfer (Developer Material
Failure) Procedure
Purpose
The purpose of this procedure is t o
determine the failure of the developer
material.
Materials Required
Test Pattern 82E5980
Scotch
TM
Brand 81 0 Magic TMTape
4024 white bond media
1. Check/Adjust the Electrostatic Series
(ADJ 9.2). and lmage Density (ADJ 9.4).
2. Select the Document Light Input and
Copy Contrast middle LED.
3. Make a copy of test pattern 82E5980.
when the copy begins t o exit the copier,
press the Stop button.
4. Remove the following:
Right Side Cover
UpperRearCover
Developer Module
5. Cut off approximately eight inches of
tape. Fold one end over t o make a half
inch tab.
6.
Rotate the Main Drive Motor backwards
in order t o access the developed image
on the photoreceptor.
7. Apply the tape horizontally over the
image on the photoreceptor. Gently
rub the tape t o ensure adhesion t o the
photoreceptor. Be careful not t o touch
the photoreceptor.
8. Using the tab on the tape, remove the
tape from the photoreceptor.
9.
Place the tape (tape transfer) on a
clean sheet of 4024 white bond paper.
10. Compare the tape transfer t o the 0.1
density gray circles on the 82E5980. If
the background (non-image area) on
the tape transfer is darker than the
circles. replace the developer material.
Automatic Toning Procedure
1. Enter the diagnostic code [47].
The main drive will come on after the
fuser is at run temperature. The toner
and cleaning blade solenoids will be
energized. The copier will continue
running and the value displayed will
flash until one of the following
conditions i s met:
a. The toner concentration is within
the control point set in Code 4. (The
display will stop flashing.)
b. The Stop button
is
pressed.
c. The 15 minute timeout limit i s
reached.
2. Refer t o the J l Low Toner Fault RAP if
the detone time approaches the 15
minute time limit.
3. Make a copy of test pattern 82E5980.
Check that the density of the .70G5
paragraph is between paragraphs 24.0
and 31.2 on the 82E7030 test pattern.
If required, perform the lmage Density
Procedure (ADJ 9.4).
