To solve the high voltage insulation failure problem for the Markem-Imaje 9020, follow these steps:

1. Clean the Deflection Plates – Use soapy water to clean the deflection plates and let them dry completely.
2. Check Inside the Print Head – Open the rear cover and clean any ink or moisture buildup.
3. Dry the Area – Ensure all cleaned components are fully dry before reassembling.
4. Inspect for Leaks – Identify and eliminate any sources of current leaks.
5. Check the EHT Block and Print Module – If the issue persists, inspect these components for faults.

These steps should help resolve the insulation failure and restore proper operation.

To resolve the "81 Default. Drop detection jet 1 (left)" error on a Markem Imaje 9020 after cleaning the head and cover, follow these steps:

1. Check Ink Quality – Ensure that the ink is of the correct viscosity. If it is too thin or too thick, it may affect drop detection.
2. Inspect Print Module Connections – Look for any cut wires in the umbilical that may be causing a connection issue.
3. Verify Jet Detection – Ensure the recovery detector is correctly identifying the jet in the gutter. Clean the nozzle and modulation assembly if necessary.
4. Check Gutter Blockage – Make sure the gutter is not obstructed, and the negative pressure is within the correct range.
5. Adjust Break-Off Point – Use a magnifier to check the drop formation under the break-off point and adjust the potentiometer carefully if needed.
6. Perform Auto-Calibration – Run the auto-calibration function to fine-tune jet stability.
7. Close the Head Cover – Ensure the head cover is properly closed, as safety mechanisms may prevent operation if it's open.

After completing these steps, perform a test print to confirm the issue is resolved.

  • Page 148: Constant Ink Concentration Principle

    Hydraulics ■ Constant ink concentration principle The printer uses the "constant concentration" principle. The ink temperature is measured continuously in the print head, using a temperature sensor on the ADP board. The jet speed is also measured continuously. Depending on the temperature measured, the ink type, and head type, a theoretical pressure is defined to obtain the correct jet speed.

  • Page 149: Jet Speed Calculation And Adjustment

    Hydraulics ■ Jet speed calculation and adjustment For high quality printing, the jet must be at a constant speed. The software continuously measures the speed and adjusts it if necessary. Jet speed calculation Speed = Distance / Time The principle used to measure the speed is as follows: A sequence of seven consecutive drops is charged with a specific, precise amount of charge when it passes through the charge electrode.

  • Page 150: Negative Pressure Measuring And Adjustment

  • Page 166: Deviated Continuous Ink Jet

    General information ■ Deviated continuous ink jet The print head is supplied with ink under pressure. This ink is ejected from the modulation assembly (1) via the nozzle (2), in the form of a jet (3). The jet is stimulated by a piezo-electric resonator in order to create consistent drops of ink.

  • Page 167: Resonator Block

    General information Resonator block The modulation assembly is a low-volume cavity in which pressurized ink is conditioned (regular jet flow, no air bubbles, modulation) before passing through the ejection nozzle to form a controlled jet. Piezo-electric resonator The piezo-electric resonator comprises a quartz crystal glued to a metal bar. When an alternating electrical signal is applied to the resonator, it vibrates in phase with the signal.
