Doctor Blade Cleaning - Gestetner B070 Service Manual

11. Re-install the toner hopper, then re-assemble the machine.
12. Tilt the toner hopper so that there is toner near the toner hopper sensor.
13. Be sure to connect the connectors after installing the development unit in the
machine.
14. Turn on the main switch, then execute SP2801 (TD Sensor Initial Setting).
• Use the keys on the screen to enter the Developer Lot No, then press .
(The Lot No. is embossed on the top edge of the developer packet.)
• Press "Execute" on the LCD.
This executes the TD initial setting. After about 1 minute, "Completed" is
displayed on the screen, and the execution stops automatically.
NOTE: Do not make copies with new developer until after executing SP2801;
otherwise, toner density control will be abnormal.
15. If the developer initial setting did not complete correctly, you cannot exit the SP
mode by pressing the "Quit" key. If this problem occurs, turn the main switch off
and on, then perform the initial setting again. If the result is the same, see
"SC342" (TD Sensor Error 3) (! "4.Troubleshooting").

3.8.3 DOCTOR BLADE CLEANING

The doctor blade must be cleaned:
• At every PM visit.
• When replacing developer.
This procedure may need to be done more often if the customer is using paper that
contains a large amount of paper dust. The dust tends to collect at the front and on
the back side of the blade, causing the doctor gap to become narrower. Cleaning is
required when:
• There is toner scatter from both ends of the development unit.
• White lines appear on copies.
• Faint reproduction of the image around the edges of the paper.
To do this procedure, you need a special tool.
