3.1 Required Adjustments
The table from the following page 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.
If the EEPROM data cannot be read out from the old Main Board using the Adjustment
Program when replacing the Main Board is required, the Waste Ink Pad Assy must be
replaced with the Main Board at the same time.
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 replacing the Main Board, the adjustment should be made after performing the
initial setting.
The table items and marks used in the “Required Adjustment List” provided on the
following pages have the following meanings.
“O” indicates that the adjustment must be carried out.
“---” indicates that the adjustment is not required.
The “Mechanism Adjustment” should be performed just after reinstalling or
reassembling the part or unit.
The “Adjustments using the Adjustment Program” need to be performed after
reassembling the printer completely.
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.
