2. When the EEPROM on a board to remove cannot be accessed:
When the operator panel displays SERVICE CALL 104 (Engine EEPROM Error)
for, or data cannot be read from the EEPROM of, a board to remove, follow the
following procedure to perform operation by using Maintenance Utility after the
board is replaced with a new one:
(1) Serial number setting (Maintenance Utility Operating Manual, section
2.4.1.1.10.3)
A SAP serial number is assigned to the printer. The SAP serial number is
at the top of the serial number label of the printer, consisting of a total of 12
characters -- two characters that indicates a production place, two characters
that indicates a month and year, six characters that indicates a manufacture
number (sequence number) and two characters that indicates a revision
number.
• Select PU Serial Number under “Select printer serial number”, and “Display
the serial number only” under Display mode. Do not enter the CU serial
number.
• The PU serial number is 10 characters a two-character revision number
excluded from the 12-character SAP serial number.
• Make settings in the window for the serial number information setting
described in section 2.4.1.1.10.3 in section 2.4.1.1.10 about board setting
functionality.
• To specify a PU serial number, in the PU serial number setting window, enter
an 11-character number with the first character a single-byte zero (0) (note a
read PU serial number is 10 characters), i.e. a 10-character number prefixed
with a single-byte zero (0), such as the number shown in the following image,
excluding the revision number two digits.
(2) Change to Shipping mode (section 2.4.1.1.10.4 of Maintenance Utility
Operating Manual)
The printer is placed in the Factory mode after the CU/PU board is replaced with
a new one. Switch the printer to the Shipping mode.
• Use the window for the Factory/Shipping mode described section 2.4.1.1.10.4
in Maintenance Utility section 2.4.1.1.10 about board setting functionality
Note: Note that replacing the EEPROM (the engine control board) clears life
information about units, including the belt, toner and image drums, causing
errors in managing the lives of the units until the units are replaced. Below is
the counts cleared with such CU/PU board replacement. When the units are
replaced with new ones, their respective counts except for Total Sheets Fed
are cleared, the errors being corrected.
