LX-105O+ Service Manual Operating Principles 2.1 OVERVIEW This section describes the operating principles of the printer mechanism and the electrical circuits of the LX-105O+.
Operating Principles LX-105O+ Service Manual 2.2.1 Printhead Printing Operation The dot-wire operation during printing is as follows. When the head-driving coil for a dot wire is energized, the actuating plate, which is engaged to one end of the dot wire, is attracted to the iron core, and drives the dot wire toward the platen.
LX-1050+ Service Manual Operating Principles 2.2.2 Carriage Drive Mechanism The carriage mechanism includes the printhead, the carriage, the timing belt, the carriage motor, and the platen. The timing belt is connected to the bottom of the carriage. The belt is driven by the carriage motor and moved via the beltdriven pulley.
Operating Principles LX-105O+ Service Manual 2.2.3 Paper Feed Mechanism Operation Friction feeding is used for cut sheets, and push tractor feeding is used for fanfold paper. Friction-Feed Operation The paper is held against the platen by paper-feed rollers.
LX-105O+ Service Manual Operating Principles Push Tractor Feed Operation When the push tractor unit is used, the paper is set such that its holes mesh with the tractor pins along the tractor belt.
Operating Principles LX-105O+ Service Manual 2.2.3.1 Paper End Sensor Following figure show the paper end sensor. This sensor switch is ON when no paper is in place (e.g., when the paper supply has run out.). ~ Paper 2 “Paper present” Figure 2-7. Paper End Sensor Mechanism 2.
LX-105O+ Service Manual Operating Principles 2.2.4 Ribbon Advance Mechanism The ribbon-feed mechanism consists of the ribbon cartridge and the ribbon-feed section. The ribbondriving gear is always driven counterclockwise (regardless of the timing belt direction) via the gear trains shown in following table.
Operating Principles LX-105O+ Service Manual 2.3 OPERATING PRINCIPLES OF THE ELECTRICAL CIRCUITRIES This section describes principles of electrical circuitries.
LX-105O+ Service Manual Operating Principles 2.3.2 Operating Principles of the Main Control Circuit The printer CPU is an 8-bit CPU ~D7810HG running at 15 MHz. It oversees control of all the components of the printer. The E05A30 gate array contains various memory management functions that control the assignment of the memory and 1/0 areas.
Operating Principles LX-105O+ Service Manual Table 2-3. Functions of the Main IC and Circuits IC and Circuits Looation Functions Receives data from the host computer and loads the data to the input buffer in RAM. Expands the input data held in the buffer to vPD781 OHG 2C create image data.
LX-105O+ Service Manual Operating Principles 2.3.2.2 Sensor Circuit Following figure shows the sensor circuit in block diagram. The PAO of CPU port senses carriage home position. The PA1 senses paper end. The PA2 senses release lever position. The AN5 of CPU A/D convertor senses +24V line voltage.
Operating Principles LX-1050+ Service Manual 2.3.2.4 Paper Feed Motor Drive Circuit The paper-feed motor drive circuit is shown in following figure. me paper-feed motor is a step motor which can utilize 2-2 phase excitation. When the paper-feed signal PC2 is set to HIGH, Q20 and Q16 are turned on, and +24 V is supplied to the motor.
LX-105O+ Service Manual Operating Principles 2.3.2.5 Printhead Drive Circuit Gate array E05A30 is used as an 8-bit + l-bit data latch. The CPU determines the pulse width for the head-wire drive pulses from gate array E05A30 by monitoring the printhead drive power (+24 V line).
Operating Principles LX-105O+ Service Manual 2.3.2.6 Host Interface The host interface circuit is shown in following figure. STROBE pulses from the host computer pass through the low-pass filter, consisting of R72 and C12, and flow into the STROBE terminal.
LX-105O+ Service Manual Operating Principles 2.3.2.7 EEPROM Circuit The EEPROM stores in its memory the current feed position of continuously fed paper, as well as the current panel settings.
