Page 31: Microprocessor
Novajet PROe Series 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 32: Memory Circuits
Novajet PROe Series Service Manual The gate array contains the hardware logic for dot firing, monitoring changes in the Carrier 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.
Page 33 Novajet PROe Series Service Manual The normal method of downloading new firmware is to send the printer a file of the new code. This requires using an appropriate host utility. This can be done through either the serial or parallel port.
Page 34: Stepper Motor Controller
Novajet PROe Series Service Manual Serial EEPROM Serial EEPROM is an Electrically Erasable, Programmable, Read Only Memory which provides storage for calibration constants and user configuration data entered from the host computer. An 8K bit serial non-volatile EEPROM stores calibration and con- figuration information.
Page 35 Novajet PROe Series Service Manual Each circuit contains four main blocks (see Figure 2-7): 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 refer- ence waveform.
Page 36: Servo Motor Controller
Novajet PROe Series Service Manual Servo Motor Controller Figure 2-8. Servo Motor Controller. The Carrier Assembly is driven by the Servo Motor. The speed of the Carrier Assembly is controlled by varying the duty cycle of the power applied to the controller. The microprocessor checks the position of the Carrier Assembly approximately 1,000 times per second (during the servo interrupt).
Page 37: Quadrature Signal Generation
Novajet PROe Series Service Manual Figure 2-9. Quadrature Signal Generation. The direction that the Carrier 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 Carrier Assembly moves left and decrements as the Carrier Assembly moves right.
Page 38: Interface Circuits: Serial & Parallel

If no paper is sensed, the paper sensor sends this information to the MPCB, which immediately begins an ‘out of paper’...
Page 41: Power Supply
Novajet PROe Series Service Manual Figure 2-12 shows the keypad after the printer has been turned on and finished the start up process. As seen in the figure, the control buttons are assigned to the corresponding command that is dis- played closest to the physical location of the button.
Page 42 This fan provides suction on the platen bed and holds the paper (media) flat during the print- ing process. The PRO 60e version has an additional suction fan located near the center of the printer inside the platen.
Page 43: Chapter 3 Maintenance
Maintenance Introduction This chapter contains general maintenance and cleaning instruc- tions for the Novajet PROe series printers. 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. Scheduled maintenance can be thought of as preventive mainte- nance since its purpose is to prolong the life of the printer.
Page 44: Cleaning Procedures
Novajet PROe Series Service Manual Cleaning Procedures Always turn the printer OFF, remove the power cord and the interface cable before cleaning the printer. An electrical shock hazard may be present if these proce- dures are not followed. External Cleaning Do not use abrasive cleansers of any sort on the sur- faces of the printer.
Page 45: Service Station Cleaning
Novajet PROe Series 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 carrier. Extreme drag results in a “carrier axis failure” fault and will stop the carrier motion. These problems may be eliminated by maintaining and cleaning the slide shaft at intervals determined by the environmental conditions.
Page 46: Linear Encoder Strip Cleaning
Novajet PROe Series Service Manual 4. Using a cotton swab dampened with distilled water, wipe the seals and the rubber wiper in the service station until no more ink residue or dust can be removed. 5. With a dry swab, wipe all moisture from the seals and wipers. 6.
Page 47: Cartridge Dimples Cleaning
Novajet PROe Series Service Manual Cartridge Dimples Cleaning Figure 3-2. Cartridge Dimple Region. 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 48: Flex Cable Contact Cleaning
Novajet PROe Series Service Manual Flex Cable Contact Cleaning Figure 3-3. Flex Cable Contacts. Cleaning the flex cable contact area is very important due to the ease of which this area can become dirty. This also causes the cartridges to not receive all of the electrical signals for a proper firing of the jets.
Page 49: Clean And Inspect Mpcb
Novajet PROe Series Service Manual reduce the quality of the intended output. Clean the motor gears with a stiff brush to knock off any debris. A cotton swab soaked isopropyl alcohol can be used to remove any ink that may have accumulated on the gears.
