Abstract: Apparatus for mounting a circuit board within the chassis of an electronic device are disclosed. The chassis of an electronic device includes a mounting panel assembly having at least one slot for receiving a standoff mounted to the circuit board. Each slot includes a first end suitable for allowing insertion and removal of the standoff through the slot and a second end suitable for engaging the standoff to retain the standoff in the slot for securing the circuit board to the mounting panel assembly. A ramp member extends beneath the slot adjacent to the first end for urging the standoff toward the second end when the standoff is inserted in the slot through the first end.

Abstract: In a line printer, an integrated meter package developing a clock incorporates a microprocessor receiving a line printed signal, power on voltage, and a preset ribbon exhaust count in order to compute in reference to the clock, and selectively display on an alphanumeric display panel, the total the lines printed, total on hours, total print hours, preset ribbon exhaust count, and number of print lines remaining until exhaustion of the ribbon. The microprocessor stores accumulated values to a non-volatile electrically programmable memory upon receipt of a power going down signal warning of incipient power off. The microprogrammed control is adaptable to maintain general maintenance and fault histories and periods.

Abstract: Commencing with the first print hammer(s) "out", or actuated, on each print line the hammer drive current is boosted 10% for a period, ranging from 25%=650 microseconds for single part forms to 50% for multi-part forms, of the total print hammer flight time. Earlier striking hammers on each print line strike harder, alleviating displaced first-printed characters on single part forms and light characters on multipart forms due to hammer energy loss in forms compression.
