TSPGs come in the following modifications: MS-6902, MS-6902.01, MS-6902.02, MS-6902.03.In addition to the internal differences between TSPG MS-6902 and the heads of the new The sample should be noted for thicker clamping pads! Therefore, when transitioning from using the TSPG MS-6902 of the old For TSPG MS-6902.01(02.03), a different one should be used carriage lock, or upgrade the old one. According to the geometric landing dimensions of TSPG MS-6902.01(02.03) are designed similarly to the heads of the company "HEWLET PACKARD" N 51604A, 51605R(G,B), 51616A, 92261A, which allows the use of The last ones in 6312 series printers if they have voltage U=22 V. TSPG MS-6902, MS-6902.01, MS-6902.02 are designed for working voltage U=16.2-17.0 V, and MS-6903.03 - for voltage U=22.2-23.0 V (complete analogue of HP heads). Currently TSPG MS-6902, MS-6902.01 are out of production removed due to the release of better modifications. TSPG MS-6902.01(02.03) consists of a resistive matrix with ca- measuring plate, body, cover, filler, filter and mesh filter. Filler with filter and filter mesh are located inside the body, which is permanently connected with a lid using an adhesive seam. In the seat the housing houses the resistive matrix assembly, fixed naya and sealed with an adhesive joint. Ink is poured- into the filler. The formation of sign information occurs due to the choiceremoving microdroplets of ink from the nozzles of the chamber-forming plate in a certain sequence onto the surface of the paper. Select spreading of microdroplets of ink occurs due to heating positive element of the matrix, boiling a portion of ink over it and formation of excess pressure between the plate and the matrix. To heat the resistive element, voltage pulses are applied. input from the control circuit through contact pads. TOTAL IN THE MATRIX HAS TWELVE RESISTIVE ELEMENTS. ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░ ELECTRICAL PARAMETERS AND MODES ░ ░ OPERATION OF TSPG MS-6902.02(03) ░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 1.

Temporary absence of selection is not considered a refusal. dew of microdroplets of ink, if as a result of following the instructions - information on the operation of heads, the functioning of the heads is fully it has been restored. Production of ink refilled at the manufacturing plant in the duration of the warranty period is not a criterion for print failure melting head. TSPGs that have been subjected to refilling or refilling during the warranty period. ATTENTION: The manufacturer accepts and replaces empty HSPGs in the warranty and post-warranty periods are not produces. ░░░░░░░░░░░░░░░░░░░░░░ ░ TSPG FAULTS ░ ░░░░░░░░░░░░░░░░░░░░░░ 1. Mechanical damage to the TSPG body or chamber- cabbage plate. Most often susceptible to mechanical damage ceramic chamber-forming plate when installing TSPG in carriage and pressing it excessively with the carriage lock. 2. Electrical damage to the resistive elements of the matrix. This malfunction most often occurs as a result of feeding on RNE of increased voltage, or due to technical printer malfunction. The integrity of resistive elements can be but check by measuring the resistance between the common terminal buses and outputs of resistive elements.3. Depressurization of adhesive joints. Appears as cracks in the adhesive joints of the TSPG: cover, chamber-forming plates, resistive matrix. 4. Clogging of the resistive elements of the TSPG.

Wipe the yellow areas on the front with a cloth dampened with water. dexterity and on the printer carriage. 2. Turn the TSPG with the metal plate down. 3. Gently press a cloth moistened with water onto the metal which record and hold it for a few seconds until it appears on ink stain tissue (using other liquids to Wetting the fabric is strictly prohibited). 4. Install the TSPG into the printer in accordance with the Instructions on its operation. 5. During breaks between use, keep the head securely but in a closed container in a cool place. ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░ ADDITIONAL INFORMATION ON TSPG░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ The head uses special ink for thermal inknoah print. Using other ink when refilling, different from those filled at the manufacturer, may lead to print head failure. Warranty period the quality of the head filled with ink at the manufacturer, equal to 10 months from the month of its manufacture. The manufacturer does not guarantee the performance of the heads - ki when refilling, however, according to the technical parameters meters, EACH RHE HEAD CAN WITHSTAND 6,000,000 OUTLET INK MICRODROPLES, WHICH IS THREE TIMES MORE THAN WITH SINGLE REFUELING. If a number of conditions are met, you can try to extend the service life of the TSPG. ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░ RECOMMENDATIONS FOR REFILLING ░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ 1. Ink intended for refilling must The chemical composition corresponds to the factory ones. Application old ink is undesirable. If sediment is detected in the ink - do not stir, but rather filter, separating the sediment. (Note: the manufacturer sells ink and reuse does not refuel TSPG). 2. Refilling is done using a medical syringe thus piercing the filler through the technological hole, located in the TSPG cover. TSPG is not allowed when refueling air bubbles getting inside along with ink.3. The best thing for TSPG is to periodically refill filling, as used, without waiting for complete production ink. IT IS RECOMMENDED TO REPLACE THE INK AS WORKINGS WITH A VOLUME OF 2-3 CM. CUB., I.E. 200-300 FORMAT PAGES A4 Shannon text GOST 21776, graphic image - in depending on print density. 4. The mass of the refilled head should be no more over 15.5 g. When conducting experiments on re-filling the TSPG The following factors should be taken into account: a) it is prohibited to clean the TSPG with alcohol, acetone, various solvents, etc. b) long-term use of TSPG with failure to print individual RNE leads to their burning or burning out. Refueling in This case will not restore their previous functional capabilities. news c) with long-term use of TSPG, RHEs lose their quality twa, carbon deposits form in them, they become clogged. When repeated gas station will not always be able to obtain the initial quality your seal. d) the use of other inks other than the factory ones, when refueling TSPG can lead to its failure. e) refueling old, long-inactive TSPGs containing ink residues or completely empty may not result in half- living result. ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░ INSTRUCTIONS FOR REFUELING TSPG ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ Store ink in a tightly closed container in a cool place. Avoid direct exposure to sunlight when sediment - filter, do not stir before filling ink - vat. Refilling should be done with a medical syringe with a diameter of a fine needle of 0.4-0.6 mm and a volume of no more than 5 cm3. Refilling process: Take a syringe, remove the air from the syringe, draw a of liquid into a syringe no more than 5 cm cube. Air does not get into the syringe allowed! Place the TSPG over the pan, the lid with the filling hole Let's go up. Insert the syringe needle into the filling hole and pierce head filler, overcoming its resistance, until it becomes solid it's time. Gently pressing on the syringe plunger, pump out the ink from syringe into the head. WHEN INK APPEARS IN THE FILLING HOLE UNTIL IT IS FULL PUMPING FROM THE SYRINGE - STOP FILLING! After filling, rinse the syringe with running water. Head temperature Wipe the bridge with a damp and then dry calico napkin. The head is ready for use. The second method is slower, more labor-intensive, but better: Pour ink into the tray. Lower the thermal jet head with the working surface into the black Nila. Using a syringe or a medical bulb, slowly pump out the air spirit from the head. Thus, creating a discharge inside the headssituation, you draw ink through the TSPG nozzles while excluding air gets into the head and, at the same time, a stream of ink nozzles and RHE are washed (refueling occurs due to the creation possible vacuum). ╔═════════════════════════════ ═════════════════════════════╗ ║░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░║ ║░░2░░░░░░░░░░░░░░░░░░░░░░░░░░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░║ ║░░░░░░░░░ SECOND VOLTAGE IN 6312 PRINTERS ░░░░░░░░░░░░░║ ║░░░░░░░░░ FOR USE OF TSPG MS-6902.03 ░░░░░░░░░░░░░║ ║░░░░░░░░░ OR HEWLET PACKARD HEADS ░░░░░░░░░░░░░║ ║░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░║ ║░░░░░░░░░░░░░░░░░░░░░░░░░░░░░ ░░░░░░░░░░░░░░░░░░░░░░░░░░░░░║ ╚═════════════════════════════ ═════════════════════════════╝ In 6312 series printers when using the TSPG series MS-6902, MS-6902.01, MS-6902.02 voltage is set to within 16.2-17.0 V. When setting a lower voltage, printing failure may occur, and when setting a higher voltage, the thermistor burns out pov TSPG.

The procedure for accessing the board is as follows:- unscrew the two screws at the bottom of the printer body and divide the top cover from it; - disconnect all plugs going to the board from the sockets on the board grid, motors, paper end sensor, stabilizer; - unscrew the two nuts (on the right) securing the controller board and two screws securing the interface connector to the body; - remove the controller board; Below you will see the stabilizer board and in the center of it the reverse Pay attention to: tuning resistor R8 (one on the board) - serves to regulate the voltage supplied to the TSPG; two points "1" and "2" (marked), connected by a jumper. To implement the second voltage it is necessary to set instead of connecting between points "1" and "2" zener diode KS-162A2 (it’s double and it doesn’t matter which side you solder), so We increase the voltage to 22.2-23 V. To switch the voltage It is necessary to connect point “1” on the stabilizer board mounting wire with a DIP switch that can be set on the controller board on the left, in a free space. Other connect the end of the DIP switch to "GROUND" on the control board Lera. Switch voltages by turning on/off turning on the DIP switch, thereby making a point-to-point connection ki "1" on the stabilizer board with "common", or by disconnecting it. Having installed the zener diode and the switch, it is necessary to setturn on the voltage with resistor R8 in such a way that in both voltage switch positions fell within the permissible limits ly for different types of heads (16.2-17.0 V and 22.2-23 V). ┌───────────────────────────── ─────────────────────────────┐ │ NOTE: ATTENTION!!!
