2-2. Ink system 2-2-1. Definitions Ink system Ink system is the general term of a mechanism specific to ink-jet printing system for protecting a nozzle against troubles such as clogging and recovering it if it should be in trouble. Head capping Head capping is a mechanism for automatically capping the nozzle so as to prevent it from drying. As long as the head is on the station in the right-hand side cover, it is capped.
2-2-2. Brief explanation of the ink system The ink system control mainly contains the following functions. • Processing when turning the power on • Processing when starting plotting • Refreshing operation • Standby operation • Ink end monitoring • Head cleaning operation • Replacement of ink cartridge • IC chip function Brief flow chart of the ink system control processing Power to the device is turned on ..... Processing when turning the power on The device waits for plotting data .....
Processing when power is turned ON If it is anticipated that the ink will have thickened while the power was OFF, and if there is expected to be danger that the uncapped nozzle will be dry when the power is turned ON, then cleaning action is executed to restore the ink ejection condition to what it was originally. While the power is OFF, the timer incorporated into the main unit is backed up by a battery. After about 7 years this battery discharges to a voltage at which the timer can no longer operate.
Head cleaning operation A function that works to remove thickened ink or dust accumulated on the nozzle faces to recover normal ink-discharge. There are the following 3 methods. Cleaning Cleaning Ink Cleaning method time consumption effect Soft Short Small Small Normal Normal Normal Normal Strong Long Large Large Remarks Can deal with minor problems such as failure of ink jet. Action is taken to clear a clogged nozzle.
2-2-3. Parameters related to the ink system To control the ink system, the following two items of parameter groups are stored on the Flash memory. • Ink parameters 1 → Any change of ink parameters 1 is prohibited since they are used to control the ink system. • Ink parameters 2 → Any change of ink parameters 2 is prohibited since they are used for experiments and evaluations in MIMAKI Development Division.
2-2-4. IC Chip Function IC chip detecting timing The read timing of the IC chip is shown below. • When the power is turned ON • When the carriage is inserted • When plotting is completed • During ink system operation (Cleaning, Initial Filling, and Filling) If the following result appears after reading the IC chip, replace the ink cartridge or attach it correctly to avoid errors. Until errors are avoided, all ink system operations (Initial Filling, Filling, Cleaning, Flashing, Wiping etc.
2-3. Brief explanation of media size detection control Detection of the front ends of a media → Detection by the paper width sensor Detection of the right- and left-side edges of a media → Detection by paper width sensor Brief flow chart of the media width detection processing Edges of the media are detected through the use of the difference in lightness between the media and the platen (cutter slit), based on which the paper width is calculated. Start the detection. Turn on the paper width sensor.

5-6. Uploading and Downloading Parameters This host computer and the plotter can be connected through the IEEE1284 or IEEE1394 interface to allow parameter loading the plotter to the host computer and parameter registration from the host computer to the plotter. 1. The function to load parameters from the plotter to the host computer (referred to as Upload hereafter). 2. The function to transfer parameters from the host computer to the plotter (referred to as Download hereafter).
5-6-2. DOWNLOAD (Computer >>> Plotter) • To realize this function, the following item is required. OS : Windows2000 / WindowsNT4.0 / Windows98SE Cable: IEEE1394 interface cable / IEEE1284 interface cable Tool: F/W Update Tool software (The IEEE1394 interface cable can be used only for Windows2000.) [Operation] 1) 2) Connect the plotter and the host computer through the interface cable.
Error messages If an error occurs, quit F/W Update Tool software and then turn OFF the poser of the plotter. Error message ERROR COMMAND POWER OFF Cause Command error Check whether interface connection is normal. Turn OFF the power and then turn it back ON. Parameter error Check whether the file selected on the host computer is for this device. Turn OFF the power and then turn it back ON. Data error Check whether the contents of the file selected on the host computer are normal and not defective.
