PCU SECTION

3.6.8 AFTER REPLACEMENT OR ADJUSTMENT

IMPORTANT: After replacing or adjusting any of the PCU components, please do
the following procedure.
1. Take 5 sample copies.
2. If black dots (dropped toner) appear on any of the copies, continue as follows.
(If all copies are clean, you don't need to carry out the following steps.)
3. Remove the PCU from the mainframe.
4. Tap the top of the PCU with a screwdriver at eight evenly spaced locations (two
or three taps at each spot), to knock the recycled toner down into the
development section.
5. Put the PCU back into the mainframe.
6. Turn the main power on. Then open and close the door and wait for the
machine to rotate the development roller for 10 seconds. Then open and close
the door two more times, so that total rotation time is 30 seconds.
7. Make some sky-shot copies (or solid black prints).
• If using A4/8
• If using A3/11" x 17" paper, make 2 copies/prints.
• To make solid black prints, use SP5-902 pattern 8.
NOTE: Step 7 is required only after parts replacement or adjustment. There is
no need to make sky-shot (or solid black) copies after replacing the
developer.
