Status reporting from accessory units in a printer |
摘要 |
<p>Two stacked paper trays (43,45) are connected electrically by cable (53) and are physically combined, as by bolts. The combined unit has a single microprocessor (49). The paper trays communicate status, such as paper size and paper amount to the microprocessor. The microprocessor reports upon interrogation from a control processor (61) of a printer (7) that it is a multiple tray unit and reports the status for each unit. This avoids the use of a microprocessor with each tray.</p> |
