PREFACE This manual is addressed to the field engineers who will install and service the CMS 140B cash register. It provides all the information needed for a correct product maintenance. SUMMARY This manual is divided into seven chapters. The first three chapters describe the operating, functional checks, and maintenance and repair procedures. Chapter 4 describes the disassembly and adjustment procedures.
2. SPECIFICATIONS AND Paper (supplied by the user) Type: Regular paper roll OPERATING PRINCIPLES Size: Width 57.5 mm ± 0.5 mm Roll diameter: 80 mm or less SPECIFICATIONS Thickness: 0.06 ~ 0.085 mm Average weight: 47 g/m ~ 64 g/m (40 ~ 55 kg/ 2.1.1 FEATURES...
2.1.3 MECHANISMS The carriage then shifts to the next column (column- shift operation). When charge to the trigger coil is This printer consist of two print wheels, a hammer, and extended during character selection at the end of a line, a carriage equipped with an ink roll.
OPERATING PRINCIPLES 2.2.1 TRANSMISSION/SELECT MECHANISM As shown in Fig. 2-2, this mechanism consists of the reduction gear train, and paper feed gear train. Fig. 2-2 Transmission/Select Mechanism 686770R Service Manual...

2.2.2 SENSOR MECHANISM (See Fig. 2-6) The sensor also generates a reset signal at each rotation of the print wheel. Waveform rectification of The sensor mechanism consists of the sensor as- these signals should be performed by the user, as sembly and the sensor gear.
2.2.3 PRINTING MECHANISM Thus, the print wheel is pressed in the direction of The printing mechanism performs two operations: arrow (4) by the hammer, and printing is performed. printing and carriage movement. The print wheel, similar to the print changeover cam, Printing operation rotates once with each printing operation, and printing is performed during the first half of the print shaft...
2.2.4 INKING MECHANISM (See Fig. 2-9) The ink roller is held lightly against the other periphery of the print wheel by the force of the ink roller spring. When the print wheel rotates, the ink roller also rotates and supplies ink to the wheel. Fig.

2.2.6 PRINT CYCLE INITIALIZATION Consecutive printing 1) The process for printing the initial line similar to To confirm that carriage is in stand-by status (at the that for “Printing the first line” above. first column), initialization must be performed prior to 2) Printing of second and later lines begins as printing and paper feeding.
3. HANDLING, MAINTENANCE HANDLING THE PRINTER 3.1.1 PRECAUTIONS ON PRINTER HANDLING Transport precautions (See Fig. 3-1) 1) When transporting the printer, never carry it by the jumper lead only. 2) Avoid impact to the printer by dropping, striking it, or collision with another printer. Fig.
Use precaution Paper insertion precautions • Since the printer employs a permanent magnet (in • Insert the paper straight into the paper entrance. the motor section), avoid using it in locations Never insert paper having an uneven leading exposed to excessive iron filings, dirt, dust, or edge;...
3.1.3 INK ROLLER INSTALLATION Mounting the Ink roller (See Fig. 3-4) • Place the ink roller in the cutout sections of the carriage, then press down gently until it clicks into place. Fig. 3-4 Ink Roller Installation Replacing the ink roller (See Fig.
MAINTENANCE 3.2.2 INSPECTION Check the printer to see if it is being operated properly To prevent potential trouble, make sure cleaning and and if it is being maintained in optimum condition. If inspection is carried out according to the points de- any unsatisfactory points are discovered, they should scribed in the following subsections, depending on the be remedied.
PROBLEM RESOLUTION In general, the printer should be replaced when problems arise. Depending on the particular problem, however, the printer may be easily repaired. Therefore, take necessary corrective actions according to the following table. In the case of problems for which no corrective actions exist in this table, the printer should be replaced. 686770R Service Manual...
