Step 3) Original Components: To avoid delays, the following components must be sent to the factory in
order to restore serial number information. There are no exceptions.
 MFP Control PWB EEPROM
 PCU PWB EEPROM
Important notes:
 Before removing each EEPROM, make a note of which direction the dimple is facing. It is critical that
the replacement EEPROM is installed in the correct orientation.
 Before removing each EEPROM, Mark or label each EEPROM. Sharp will NOT be able to identify
which EEPROM came from which PWB. You must label them.
 EEPROMs must be protected by placing the legs of the EEPROM in anti-static foam.
 NEVER
ship EEPROMs in an Envelope!
Step 4) Replacement Components: To avoid delays, the following replacement components must be sent to
the factory in order to restore serial number information. There are no exceptions.
 MFP Control PWB EEPROM
 PCU PWB EEPROM
Step 5) Packaging: To avoid delays, please take care that all components are packaged properly and are
well protected. All electronic components must be wrapped in anti-static material. Also take care to label the
package Ship To: information correctly.
Always ship EEPROMs in a carton, never ship EEPROMs in an envelope.
Step 6) Shipping: Please send the Documentation, Original Components, and Replacement Components in a
carton to the following address:
Sharp Electronics Corporation
DSSD Dept. ATTN: TY SMITH
1300 Naperville Drive, Romeoville, IL 60446
Warning:
 Include DSSD Dept. ATTN: TY SMITH, or else the package may not reach the intended recipient for
several days.
 Never ship the components in an envelope, or else severe damage will occur.
 Protect the legs of the EEPROMs in anti-static foam, or else severe damage will occur.
 Wrap the components in anti-static plastic, or else severe damage will occur.
 Do not forget to include all documentation outlined in Step 2.
Factory will analyze the original components to identify root cause of U2-30 error.
Serial number Data will be programmed onto Replacement components, and tests will be made to confirm
that the U2-30 has been eliminated.
Original components will be destroyed.
