15.3 CLEAR ALL MEMORY PROCEDURE
CAUTION: The Clear All Memory procedure (SP99) resets all the correction
data for copy process control and all the software counters, and
returns all modes and adjustments to the default settings.
Normally, this SP mode should not be performed.
This procedure is required only when replacing the EEPROM or
when the copier malfunctions due to a damaged EEPROM.
1. Enter SP mode. (Refer to the SP mode access procedure on page 8-34.)
2. Enter "99" with the number keys, then press the key to view the
current setting.
3. Enter "1" with the number keys, then press the and keys at the
same time.
NOTE: The Manual Image Density indicator blinks back and forth when
the above procedure is completed. Be certain to complete the
following.
4. Clean the used toner tank, since the toner end counter has been cleared.
(See Used Toner Removal in the A151/A152 Service Manual.)
CAUTION: Skipping this step will cause the used toner overflow condition
not to be detected properly.
5. Load new developer. (See Developer Replacement in the A151/A152
Service Manual.)
NOTE: Since the software counter for the development bias voltage in
the toner detection cycle has been cleared, –20 volts will be
applied to the development roller for the initial 499 copies.
6. Clean the optics, sensors, and inside of the copier if necessary.
7. Refer to the "FACTORY SETTING" table located inside the upper slit of
the inner cover and enter the data for:
1) SP60: Standard Image Grid Voltage Setting
2) SP62: Standard ID Sensor Grid Voltage Setting
