■ Ink filters
The primary filter is inside the accumulator on the ink circuit. It cannot be changed.
To reach the 14 µ grid filter on the SV 11 inlet, remove the solenoid valve's support bell. Removing
the filter is not recommended (risk of ink circuit contamination).
■ Make up filter
In order to filter the make up which is directly aspirated out of the cartridge during the head rinsing, a
5 µ filter screen is located between the make up tip holder and the ink circuit. To reach the filter
screen, remove the tip holder.
■ Calibrated restrictors
The hydraulic system has three restrictors located in the print head.
The first is in the hose exiting the recovery gutter solenoid valve. This restrictor optimizes the
recovery signal. It is able to be changed if necessary.
WARNING: The restrictors have a diameter of:
- 0.7 mm for 1.1G, 1.2G and 1.2M printers
- 0.5 mm for 1.1M printers
A second restriction measuring 0.6 mm is built in to the gutter in order to reduce the air intake and
thereby optimize make up consumption. The entire gutter is interchangeable.
The third restriction is located at the refreshment exit of the modulation chassis. Its diameter depends
on the modulation assembly type. The modulation chassis is interchangeable.

How To Solve 9020 High Voltage Insulation failure Problem.
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.

81 Default. Drop detection jet 1 (left) Clean and dry carefully head and cover... Done this numerous times but error returns
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.
