Line quantity correction IC
This IC corrects voltage changes of head elements that is turned on the electricity by 1 line.

Data is input from IC208 through 210, according to it’s data quantity, width of head STROBE (CN7-
25) is adjusted.

Head voltage control

This unit does not need the head voltage adjustment basically. But head voltage is not always
stabilized by heat store of the head or difference between papers. When head voltage is less than 16V

or more than 23V, the head or power supply is abnormal.
