An adjustment value for printing deviation between forward and reverse printing passes is set for each width of printing paper. The printing deviation is adjusted by, for example, varying, in the main scanning direction, the frequency of the drive clock signal (CLK) applied to the print head (28). The drive clock signal frequency (fCLK) is individually set for each of a plurality of regions into which the main scanning range is divided. |

5 | Ruggedized typebar guide | US3729080D | 1971-06-01 | US3729080A | 1973-04-24 | MUELLER H |
A ruggedized typebar guide is disclosed comprising two spaced pivots and two guide dogs rotatably mounted to the pivots with each guide dog having spaced opposing cam surfaces respectively disposed along opposing sides of a typebar flight path. Shock absorbing means are provided permitting limited movement of the pivots in a direction substantially parallel the flight path upon rotation of the guide dogs. Means are also provided for rotating the guide dogs about the movable pivots upon passage of a typebar between the guide dogs along the typebar flight path to converge the two opposing cam surfaces towards one another a predetermined distance within the flight path to center the typebar.

Described is a printing system including a first array of ink ejection elements (82) formed on a first substrate (88) surface for ejecting droplets of a first ink, a second array of ink ejection elements (82') formed on a second substrate (88') surface for ejecting droplets of a second ink, a memory element (78) associated with the first and second arrays of ink ejection elements contains parameters that relate droplet ejection characteristics of the first and second array of ink ejection elements. The droplet ejection characteristics may contain ink ejection alignment data that enables the calculation of the relative alignment between the first and second arrays of ink ejection elements such that droplets of the first ink can be effectively aligned with droplets of the second ink. Also, ink droplet volume data enables the calculation of the relative drop volume between the first and second arrays of ink ejection elements such that the printing system can provide hue control. |

The value for adjusting the printing misregistration between one way and the return way is determined for each of the printing papers having different widths. The printing misregistration is adjusted by, for example, changing the frequency of drive clock signal given to the print head in the direction of horizontal scanning. The frequency of drive clock signal is separately set for each of regions defined by dividing the horizontal scanning range. |
