5.4.3 Data in the EEPROM
The EEPROM stores the absorption amounts of the waste ink absorber and vertical
alignment data.  The non-volatile EEPROM does not require any electrical power to retain
the data it contains.
Calculation of the total waste ink amount of the waste ink absorber starts immediately
after the printer is used.  When the absorption amount of the waste ink absorber reaches
100 percent, the waste ink full error is generated and the printing operation is stopped to
prevent the waste ink from leaking out.
The vertical alignment data is for correcting any vertical misalignment during bi-
directional printing.
The data in the EEPROM can be checked or altered.
Checking or altering the data in EEPROM
Waste ink absorption amount:
To check the amount, use the service report’s System Dump List.  For
details, see 
Chapter 3: a-2) System dump list on Page 3-62
.
To enter the amount, use the service data #7 PRINTER 3. INK ABS
CAPA. For details, see 
Chapter 3: 5.2.5 New SSSW's/parameters added to
this model on Page 3-41
.
Vertical alignment data:
To adjust the vertical alignment, see 
Chapter 3: 3.2 Vertical Alignment
Correction on Page 3-7
.
Re-entering the waste ink absorber’s ink absorption amount.
The amount data is calculated one waste ink absorber.  The waste ink
absorption amount displayed in the 
SYSTEM DUMP LIST
indicates the
percentage of the respective absorber’s maximum capacity that has been
reached.  The percentage can be indicated and entered in 1% increments.
When the waste ink generated immediately after the printer is used reaches
100 percent of the waste ink absorber’s capacity, a waste ink full error is
generated for each absorber and the printing operation is stopped.  Therefore
when replacing the PCNT board, be sure to check the current absorption
amount and enter it in the new PCNT board.
If the PCNT board assembly malfunctions and the current waste ink
absorption amount cannot be checked, replace the ink absorber and set the
waste ink absorption amount to 0%.  To replace the ink absorber, see 
e) New
error codes and recovery methods on Page 3-24
