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 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.
2-3. 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.
