Downloads, quick checks and a clearer path to help.

Confirm the print repeat is entered correctly, the mark sensor is positioned in the path of the register marks and reregister is turned on. Let the first few marks pass so the sensor can calibrate and the automatic mark window can calculate before making fine adjustments.

The manual identifies this as the mark sensor not reading print marks while reregister is on. Check mark visibility, sensor alignment, sensor mode and whether the web is presenting a consistent mark/background contrast.

Solid red indicates guards are open or the system is in error. Close guards if safe, go to the Tools page, press Clear Error, wait for the status light to flash orange and then press Motor Engage. If the fault returns, stop and call Servo.

Print length is the key factor in a reregister job. Measure the distance between register marks over an approximate 10-foot span and note whether it is short, long or dead on. If the print length is too short, web tension can rise and slipping can occur; if too long, the system may overfeed and lose web tension.

Use Dynamic mode for auto calibration during reregister setup. Align the sensor to either the mark or background, start Dynamic sampling, move the web past at least two marks and end sampling. If teach fails, improve mark-to-background contrast, clean the lens area and repeat the teach procedure.

Check sensor distance and angle. The manual notes a 10 mm focus distance, plus or minus 3 mm. For reflective material, angle the sensor about 15 degrees off perpendicular. For clear material, use a reflective surface behind the web and keep the skew angle to reduce glare.

Review the Infeed Value, motor torque display and press behavior. Lower Infeed Value means more web tension. If reregister is on, the Infeed Value adjusts automatically to hold the best possible registration, so document the value changes before adjusting other variables.

The gripper wheels are automated: they are off when guards are open and on in run mode. Confirm the machine is reset, the motor is engaged and shop air is connected. The manual calls for the air regulator to be set around 40-50 psi for gripper wheel pressure.

On setup, jog the press and confirm the infeed cylinder turns with the web direction. If it turns opposite the web, the Motor Direction setting on the Program Tools page needs to be changed by a qualified technician.

The manual is direct here: the correct Encoder Repeat value is critical. If the encoder value or gear type does not match how the encoder is installed, the system will not work properly. Record the current Encoder Repeat, Gear Type and Print Repeat before contacting Servo.

Inspect the air filter, servo motor drive belt and gripper wheels. The manual recommends cleaning the air filter every three months, inspecting the drive belt every six months and replacing gripper wheels when visibly worn.

The SVX is equipped for remote communication through an industrial VPN router. If Servo support asks to connect, plug in the Internet connection and have the press make, web width, application, current symptom, status-light state and recent setup changes ready.
