7.2 Required Adjustments

The following table lists the required adjustment items 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.

After all required adjustments are complete, 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.
