Clockwise rotation of the RF motor is transmitted to the tractor select cam through the ribbon feed select gear and tractor select transmission gear, and rotates the tractor select cam clockwise. The tractor select lever contacts the inside curve of the cam due to the spring force; when the cam rotates, the tractor select lever moves horizontally along the curve.

The only difference in the operation of these two boards is in the primary circuitry. They supply power to the printer in the same way. The power supply board outputs the DC current required to drive the control circuits and printer drive mechanis-rn.
PAGE 52
DFX-5000+ Sendee Mama! e O~atfng Princi@aa The power supply board converts the AC voltage to the DC voltages required to operate the printer. The AC voltage is input to the AC inlet, and is supplied to the C117 power supply board assembly via the power switch and fuse. l’hree switching regulator circuits convert the AC voltage to the three DC voltages (+35 V, +5 V, and +/-12 V) required to operate the printer. The power supply board contains two +35 VDC creation circuits.

Operating Principle DFX-5000+ Service Manuai SpeeciO - SP1 1. It causes the carriage to accelerate. 2. Because the control circuit measures time periods with the encoder signal, when the carriage speed reaches SP1, it changes to the next sequence (SP1 - SP2). SP1 - SP2 1. The DFX-5000+ printer has a table programmed into its main program ROM to determine the duration of the acceleration pulses. This table is called the duty data table. Duty data is divided into ten sections, plus Dutymin.
PAGE 68
Current speed - SP3 1. The duty data for deceleration control is determined for each printing mode beforehand and programmed into a table in the main program ROM. Duty data is divided into 19 sections, plus Dutytil. Section 1 is the largest, and Dutytil represents the minimum duty data for deceleration amtml. Pulse width modulation (PWM) determines each section number. For each section, the carriage motor driver is turned on part of the time and off part of the time. 2.

Adjustment DFX-5000+ Service Manual 4.1.3 Tractor Wire Spring Tension Adjustment describes the tractor wire spring tension adjustment. If the spring is not adjusted properly, paper jams may occur, because the continuous paper tension (in the horizontal direction) is incorrect. When you remove the front or rear tractor assembly, perform this adjustment. This section 1. Remove the printer mechanism. (Refer to Section 3.2.6) 2. Release the release lever for the tractor sprocket. 3.

DFX-SOOO+ Service Manual Adjustment 4.1.5 Carriage Guide Shaft Parallelism Adjustment The rear carriage shaft must be parallel to the platen. If it is not, printing maybe abnormal because paper is not fed evenly at the left and right sides of the platen. A paper jam may occur. This adjustment is required when the rear carriage guide shaft is removed during carriage mechanism disassembly, the parallelism adjust lever is moved, or the platen is removti.
