Ink-jet printer control equipment, has control arrangement with clock change over switch to switch between two clock adjusting devices based on conveyor belt joint detector output, where devices adjust clock impulses output by speed sensors

摘要

The equipment has a control arrangement (10) with a clock change over switch (14), which switches between two clock adjusting devices (12, 13) based on a conveyor belt joint detector output. The devices adjust clock impulses, which is output by two speed sensors (8, 9) proportional to sheet feed rate. The impulses control the ink output of a nozzle of an ink-jet printer. The sensors are coupled with two discs (5, 6) contacting the belt.
