To correct the head convergence:
Utilities Vx.xx Exit Next
Head convergence <nn> Change Next
In the following example, select a higher number than the current setting to move the center line to the right. For example, if the current setting is 0, select +1.
If the head convergence test pattern resembles the following example, select a number that is lower than the current setting to move the center line to the left. For example, if the current setting is +0, select -1. (Factory default is 0.)
If the proper head convergence cannot be achieved by using the -4 to +4 range, there may be a problem with the printer. Call your dealer or Tektronix service.
