AID Issue Troubleshooting
Overview
The AID (Auto Ink Detection) feature is designed to perform auto nozzle checks. It has 3 settings that were added
with a recent firmware revision. There are 3 options in the:
User Menu: Printer Settings / AUTO NOZZLE CHECK: ON:PERIODICALLY*, ON:EVERY JOB, OFF.
Even if the Auto Nozzle Check is set to OFF, the Aid Circuitry is still used after a cleaning cycle to verify the results.
Troubleshooting
1. Verify that the latest firmware is installed.
1.1 The latest firmware has been adjusted for more consistent operation of the AID process.
1.2 The latest firmware has improved customer options. The user has control over how many times the Printer
repeats a cleaning cycle when the AID reports missing nozzles.
1.2.1 Maintenance Mode 1: AUTO CLEANING TIMES: 1, 2, 3
2. Perform a nozzle check and verify that all of the Printer’s nozzles are working.
2.1 Missing nozzles on a Print Head can be misinterpreted as an AID error.
3. Perform an AID Check.
3.1 Enter Self Testing mode: Down, Right, and OK buttons, and turn on the Printer.
3.2 Navigate to SELF TESTING\Mecha Adjustment\AID Check
3.3 Press the Right Arrow.
