Hi
The sensors involved in the bid OPE signal test are generally located in areas where they can monitor the performance of the BID system and the print engine.
BID Base Area: Some sensors are positioned near the BID base to monitor the development process and ensure proper transfer of ink to the photoconductor. These might include sensors that check the position, movement, and condition of the BID roller.
Inside the Print Engine: Additional optical sensors could be located deeper inside the print engine, possibly near the photoconductor or intermediate transfer media, to verify the consistency and alignment of the printed image.
Near the BID Rollers:There could be sensors around or near the BID rollers themselves. These sensors help monitor the even distribution and application of the ink, ensuring that the BID rollers are functioning correctly.
Behind the BID Units: When you push the BID units back into place, there might be sensors positioned to check the alignment and engagement of the BIDs within the print engine.
To clean these sensors Turn off the press and follow all safety protocols.
Locate the sensors near the BID base or BID rollers, as described in your machine’s manual.
Use a lint-free cloth and isopropyl alcohol to gently clean the sensor surfaces. Be careful not to apply too much pressure. Check the sensor connections to ensure they are properly seated.
Reinstall the BID units carefully after cleaning, ensuring they are fully engaged with the press.
Run the Bid OPE test again to see if the issue is resolved.
If the issue not solved the sensors might be more deeply integrated into the machine's optical system.
