Paper Feed Mechanism

Manual Tecnico Dfx 8500

Cut sheet paper is advanced by friction feed. Continuous form paper is advanced using a tractor feed mechanism. There are three ways to advance the paper with tractor feed using the push tractor, using the pull tractor, using the push and pull tractors together. Any one of these three tractor configurations can feed paper through the printer. In normal operation, the printer is set up with one tractor, which functions as either a push tractor or pull tractor, depending on where it is attached...

Sensor Circuits

Figure 2-21 shows the sensor circuits in block diagram form. Detection of any excessive printhead temperature causes the TEMP2 signal to be sent directly to the CPU. Other signals, such as the CRHOME signal, pass through the STK-6022B unit before reaching the CPU. Terminals P50toP55on the CPU are used for the A D convertor. The Vref circuit generates the A D convertor reference voltage Vref. Figure 2-21, Sensor Circuit Block Diagram Figure 2-21, Sensor Circuit Block Diagram 2.3.4 MOTOR, CR...

Control Circuit Operation Overview

The printer CPU is an 8-bit CPU TMP90C041 running at 10 MHz. It oversees control of all the components of the printer. The E05A50 gate array contains various memory management functions that control the assignment of the memory and I O areas. Rationalization and simplification of the circuitry is achieved through use of the STK-6022B, which holds all the driver circuits for driving the PRINTER MECHANISM on a single chip. Figure 2-17 shows the control circuits in block diagram form. I 1...

C Psbpse Board Power Supply Circuit Board

The power supply unit consists of a switching regulator circuit, which converts the AC line voltage to the DC voltages for example, 35V and 5V used by the printer. The C062PSB board is 120V input type, and the C062PSE board is 220 240V input type. 1.7.4 Printer Mechanism M-5 E10 M-5E60 The M-5E10 M-5E60 printer mechanism was developed specifically for use with LQ-570 1 070 printer. The components include a carriage motor, carriage mechanism, paper-feed motor, paper-feed mechanism, ribbon-feed...
