Abstract

A straightforward design of a high speed line printer (e.g., 14,000 1pm) requires very high speed (<<1 ms) reactions using molecular matrix printing. This difficulty can be overcome by using a matrix head, e.g. 2,000 x 8 versus 2,000 x 1, and synchronously switching the written information along the 8 lines so that the written spot stays fixed relative to the paper as the paper moves relative to the head. The principle is similar to that used in timve delayed integration in array scanners. Here we do the inverse. Using this technique molecular matrix printing (MMP) chemicals of lower speed and sensitivity can be used.

Synchronously Scanned Array Printhead For MMP

A straightforward design of a high speed line printer (e.g., 14,000 1pm) requires very high speed (<<1 ms) reactions using molecular matrix printing. This difficulty can be overcome by using a matrix head, e.g. 2,000 x 8 versus 2,000 x 1, and synchronously switching the written information along the 8 lines so that the written spot stays fixed relative to the paper as the paper moves relative to the head. The principle is similar to that used in timve delayed integration in array scanners. Here we do the inverse. Using this technique molecular matrix printing (MMP) chemicals of lower speed and sensitivity can be used.

The general principle is to use a head with N x M elements, as in the figure, rather than a linear array of N elements. This principle applies to both serial and line printers and substitutes more circuitry for more complex chemistry.

Heads implementing this technique can be designed using multilevel ceramic technology with chips packaged on the head itself.
