2.1 Required Adjustments
The table below lists the required adjustments depending upon the parts being repaired or replaced. Find the part(s) you removed
or replaced, and check which adjustment(s) must be carried out.
Note: <Meaning of the marks in the table>
“O” indicates that the adjustment must be carried out. “O
*
” indicates that the adjustment is recommended. “---” indicates that the adjustment is not required. If you have
removed or replaced multiple parts, make sure to check the required adjustments for the all parts. And when multiple adjustments must be carried out, be sure to carry out
them in the order given in the “Priority” row.
When the EEPROM Data Copy cannot be made for the Main Board that needs to be replaced, the Waste
Ink Tray Assy must be replaced after replacing the Main Board with a new one.
After all required adjustments are completed, use the “Final check pattern print” function to print all
adjustment patterns for final check. If you find a problem with the printout patterns, carry out the
adjustment again.
When using a new Main Board for replacing the Printer Mechanism, the Initial setting must have been
made to the Main Board.
