CR Measurement Sequence To set the appropriate drive current value according to the CR mechanical load, the mechanical load is measured in a CR measurement sequence and saved into the EEPROM at power-on or after replacing the Ink Cartridge(s). The above control and sequences correct the drive current value of the CR Motor according to not only the mechanical load but also the variations of the motors. In addition, the resultant CR drive current value is used to calculate a heating value, and when the specified heating value is reached, wait time is provided per CR path for printing.
2.2.1 Carriage Mechanism
The Carriage mechanism consists of parts/units such as the Carriage Motor (CR Motor), Carriage Shafts, Platen Gap Adjustment Mechanism and Carriage Lock Mechanism.
2.2.1.1 Carriage Mechanism
The following indicates the specifications of the CR motor (DC motor) that drives the Carriage. Table 2-2. CR Motor Specifications
Item Type Drive voltage Armature resistance Inductance Drive method Drive IC Specifications DC motor with brushes +42V ± 5% (voltage applied to driver) 23.6 ± 10% 17.5mH ± 25% PWM, constant-current chopping A6628
Closed loop control based on the CR Motor (DC Motor) and CR Encoder Sensor has advantages in stabilized print quality and silent operation. Heat Generation Control The printer has a mechanism to reduce the variations in the torque constant and coil resistance of the DC motors, and variations in output voltage of the Power Supply Board to obtain a designated heating value. CR Variation Measurement Sequence The variations mentioned above are measured in a CR variation measurement sequence when the CR mechanical load is in the initial status and saved into the EEPROM. According to the saved information, the printer controls the drive voltage to obtain a designated driving current. This minimizes the unit-to-unit variation.

2.2.1.2 Carriage Home Position Detection
As in the previous model, the Carriage Home Position is detected using the drive current of the CR Motor and the speed/position signal of the CR Linear Encoder. The basic home position detection sequence is described below. 1. 2. The CR linear encoder pulse counter in the CPU is reset by the initialization operation performed at power-on. When the CR Motor rotates counterclockwise, the Carriage Unit moves from left to right. When the following conditions are satisfied, the CPU assumes that the Carriage Unit made contact with the right frame. The ASIC detects 935/1500 counts or more in the PWM output under CR Motor load positioning control. P1 (number of output pulses from when the power is switched on till the Carriage Unit makes contact with the right frame) is 19 steps or less. 3. When the CR Motor rotates clockwise, the Carriage Unit moves from right to left. When the following conditions are satisfied, the CPU assumes that the Carriage Unit reached the CR lock confirmation position. The ASIC detects 600/1500 counts or more in the PWM output under CR Motor load positioning control. A difference between P1 and P2 (number of output pulses from when the Carriage Unit made contact with the right frame until it reaches the Carriage lock confirmation position) is 19 steps or less. 4. When the CR Motor rotates counterclockwise to move the Carriage from left to right and the CPU detects 935/1500 counts or more in the PWM output under CR Motor load positioning control, the printer judges that the Carriage has moved to the far right position (in contact with the right frame). When a difference between P1 and P3 (number of output pulses from when the Carriage Unit reached the Carriage lock confirmation position until it makes contact with the right frame) is 4 steps or less, the printer judges that the Carriage Unit is in the home position.
2.2.1.3 Sequence Used for PW Detection
The PW (paper width) Sensor installed on the bottom of the Carriage Unit is used to control the printer according to various sequences. The following briefly describes the operating principle of the PW Sensor. A dark voltage is measured by the PW Sensor in three places at the right flat area (area without the absorber) on the Front Paper Guide every time the printer is turned on, and the measurement values are saved into the EEPROM as threshold values. Threshold value Threshold value detection voltage: Paper present detection voltage: Paper absent
The following sequences are performed. Detection of Left and Right Edges of Paper Control Before Printing The printer sets the print range according to the paper-size information from the Driver and the actual paper-size detected by the PW sensor. During Printing When executing a borderless printing, the printer sets the off-range margins by detecting the paper edges with the PW Sensor. When the resolution is 1440 x 1440 (VSD3) or 2880 x 1440 (VSD3) dpi, the printer performs the OffRange Thinning Out Control to make a further correction to the off-range margins. Detection of Top Edge of Paper Control Before starting a print job, the printer detects the top edge of a loaded single sheet of paper to set the off-range top margin. (Only when not detecting the top edge of paper with the PW Sensor.) Detection of Bottom Edge of Paper Control After starting a borderless printing, the printer sets the off-range bottom margin. Detection of Edges of CD-R Control Before starting to print, the PW Sensor detects top, bottom, left and right edges of the CD-R. See Section 2.2.3.3 CD-R Printing Mechanism on page 29.
5.
IC9 (CPU-ASIC) sets the drive current value adequate for the Carriage Unit motion and outputs it to the motor driver. Based on the signal output from IC9 (CPU-ASIC), IC11 (Motor Driver) outputs the CR Motor drive current to the CR Motor.

The measurement voltage in the presence of the CD-R is saved into the EEPROM as a white level. The white level value is used to check the sensor deterioration condition on occasions such as servicing. · If the measurement value of the white level is close to that of the PW detection level, it means that the sensor is dirty or deteriorated.
The APG Motor (DC Motor) and two APG Sensors drive the PG Cam to automatically adjust the PG amount according to the paper.

2.2.6 Ink Sequence
The following ink sequence is executed according to various timer, counter, flag and other information saved on the EEPROM. Initial Ink Filling When the printer is powered on for the first time after purchase, the printer executes the initial ink filling operation to fill the ink cavities of the Head with ink. When the initial ink filling operation is performed properly, the printer clears the flag in the EEPROM so that initial ink filling operation will not be performed when it is powered on the next time. The Stylus Photo 1400/1410 requires about 170 seconds to perform the initial ink filling operation. If the sequence does not end normally during initial filling, the initial filling flag is not cleared and the CL operating flag is set. Because of these flags, when powered on the next time, the printer assumes that it was powered off for some reason during initial filling and executes CL3 instead of the initial filling sequence. (On the previous model, initial filling was executed again. However, when this operation was performed, ink was wasted and therefore CL3 is executed to cover for the ink filling performance.) When the initial filling flag is set and the CL operating flag is not set, the printer judges that the initial filling was not executed at all (power was switched on but the cartridges were not installed), and when the printer is powered on the next time, it executes initial filling.

Manual Cleaning This printer provides three different manual cleanings to remove ink coagulated by air bubbles, viscous material, or foreign matter. Perform the following manual CL operations by operating the panel or using the utility included in the printer driver. Independently of the printing path after the previous CL, perform manual CL from CL1 to CL3 in order if the cumulative printing timer counter is less than 9 minutes. When the cumulative printing timer counter is more than 9 minutes, only CL1 is executed. Wiping Operation Clean the nozzle surface, with the right-half of the rubber part on the wiper. Flushing Operation Prevent color mixture. Stabilize the ink surface inside the nozzles. In addition, the printer determines which CL to perform according to the remaining amount of ink in the Cartridge. When the printer detects the amount is low, it automatically choose the CL that uses ink less than the other CLs. If the remaining amount of ink is extremely low (Ink Low or Ink End status), the printer disables the all the manual cleanings and indicates the status on the STM3. Timer Cleaning Ink is consumed depending on the combination of the cumulative printing timer, cumulative cleaning count and cleaning timer. Flushing There are two types of flushing. Flushing before printing This is performed to reduce the viscosity of ink in the Printhead nozzles before starting to print. Scheduled Flushing This is performed to prevent ink in the Printhead nozzles from increasing its viscosity during printing. 3. 4.
