  • Page 23: Chapter 2 Theory Of Operation

    This chapter explains the mechanical and electrical theory of operation of the ENCAD CadJet 3D color inkjet printers. The CadJet 3D is a PowerPC 33MHz microprocessor-based digital printer that receives plotting instructions from a host computer through the Centronics parallel interface. This interface is either connected directly to a computer or through a network print server.

    Misaligned pinch wheels is a main cause of skewing the media. For that reason the CadJet 3D was designed with self aligning pinch rollers. As the media is fed forward, the rollers are aligned correctly.

  • Page 26: The Carriage Axis Drive

    CadJet 3D Service Manual The Carriage Axis Drive Figure 2-3. Carriage Axis Drive. The Carriage Axis Drive moves the printer’s carriage assembly along the length of the printer. The drive consists of a servo motor, linear encoder strip, drive belt, and tensioning assembly. These items are illustrated in Figure 2-3.

  • Page 28: Microprocessor

    CadJet 3D Service Manual Microprocessor The microprocessor (an IBM PowerPC) is the central processor unit which supervises system functions, executes the printer firmware, manipulates data, and controls input/output data busses. It has two built-in serial ports, a two channel DMA (Direct Memory Access) controller, a timer module, clock generator, and an on-board chip select generator.

  • Page 29: Memory Circuits

    CadJet 3D Service Manual The gate array contains the hardware logic for dot firing, monitoring changes in the Carriage Assembly position, controlling DMA through the parallel port, and generating the PWM (Pulse Width Modulation) waveforms for the servo controller. The gate array is a Xilinx device. It is a static RAM-based field programmable gate array.

An 8K bit serial nonvolatile EEPROM stores calibration and configura- tion information.
  • Page 32 CadJet 3D Service Manual Each circuit contains four main functions (see Figure 2-6): 1. Reference waveform generator The microprocessor uses a D/A (digital to analog) converter to set the desired level for the current in the stepper motor winding. The output of the D/A converter varies in time to create a reference waveform.

  • Page 33: Servo Motor Controller

    CadJet 3D Service Manual Servo Motor Controller Figure 2-7. Servo Motor Controller. The Carriage Assembly is driven by the Servo Motor. The speed of the Carriage Assembly is controlled by varying the duty cycle of the signal applied to the controller. The microprocessor checks the position of the Carriage Assembly approximately 1,000 times per second (during the servo interrupt).

  • Page 34: Quadrature Signal Generation

    CadJet 3D Service Manual Figure 2-8. Quadrature Signal Generation. The direction that the Carriage Assembly is moving is known based upon the state of one detector’s output and the direction of the transition of the other detector’s output. A hardware counter in the gate array increments as the Carriage Assembly moves left and decrements as the Carriage Assembly moves right.

    (DTRCLK) meets the RS-423 electrical specifications. Due to the data flow speed limitations of using the serial interface with a Macintosh computer system ENCAD does not recommend using this port for production usage with these printers. Hesitation may result if using this port and that can degrade the quality of the output print.

  • Page 37: Control Panel

    CadJet 3D Service Manual The paper sensor circuitry senses for the presence of loaded media. It does this automatically during the start-up and load sequences. It also constantly monitors the media during printing to determine if the media has run out.

  • Page 38: Power Supply

    CadJet 3D Service Manual Power Supply An internal UL recognized switching power module supplies power for the printers. It provides a constant 24VDC output from input voltage in the 90-132 VAC and 180-246 VAC ranges. A power switch turns the power on and off.

    Maintenance Introduction This chapter contains general maintenance and cleaning instructions for the CadJet 3D printer. Scheduled Maintenance Scheduled maintenance consists of a list of checks that are planned to be performed on a regular basis or when conditions warrant it.

  • Page 40: Cleaning Procedures

    CadJet 3D Service Manual Cleaning Procedures Always turn the printer OFF, remove the power cord and the interface cable before cleaning the printer. An electri- cal shock hazard may be present if these procedures are not followed. External Cleaning Do not use abrasive cleansers of any sort on the surfaces of the printer.

  • Page 41: Service Station Cleaning

    CadJet 3D Service Manual Printer problems can be caused by an accumulation of dirt or other contamination on the slide shaft. This contamination may lead to drag on the carriage. Extreme drag results in a “carriage axis failure” fault and will stop the carriage motion. These problems may be eliminated by maintaining and cleaning the slide shaft at intervals determined by the environmental conditions.

  • Page 44: Flex Cable Contact Cleaning

    CadJet 3D Service Manual The cartridge dimple area can easily be contaminated by oils and dirt on fingers and hands or ink spilled onto them. This causes the cartridges to not receive some of the electrical signals for a proper firing of the jets.

  • Page 45: Clean And Inspect Stepper Motor Gears

    CadJet 3D Service Manual Cleaning the flex cable contact area is very important due to the ease of which this area can become dirty. The flex for the yellow cartridge is deceiving because it is not readily apparent that it is dirty. This also causes the cartridges to not receive all of the electrical signals for a proper firing of the jets.

  • Page 46: Clean And Inspect Carriage Assembly

    CadJet 3D Service Manual Clean and Inspect Carriage Assembly Foreign material on the carriage assembly could short out signals being developed on the carriage assembly and cause erroneous prints or even damage to the carriage assembly.

  • Page 61: Color Calibration

    CadJet 3D Service Manual NOTE The actual measurement is different than the true head height due to the fact that the test cartridge does not con- tain a jet plate assembly. A difference had to be calcu- lated to compensate for the lack of a jet plate assembly on the test cartridge.
