Troubleshoot this issue step by step: Check the Feed Selection Lever: Ensure that the Feed Selection Lever (located on the lower left side of the front of the scanner) is in the correct position (up) for separation. Straighten the edges of the stack of documents to be scanned. Set the document guides so they are wider than the document to be scanned. Place the documents face up into the feed tray, ensuring they touch the document stoppers. Clear Any Jammed Paper: Be careful when removing jammed paper to avoid cuts. Remove any documents that have been left in the eject tray. Close the document eject tray. If the document ejection is stopped partway, perform this operation with the document eject tray extension open. Hold the upper unit as shown in the diagram and open it to the point where you can remove the jammed document. The pickup roller is located in the middle of the upper unit. Do not hold the protrusion on the upper unit when opening it, as it may deform the pickup roller or cause a feeding error. Close the feeder cover. If the jam occurred in the feed section, pull the document out carefully without applying too much force. Be sure to remove any torn parts remaining in the scanner. Close the upper unit slowly, ensuring it clicks into place. Do not force it to close, as this may damage the scanner. After removing the jammed paper, check if the last page was scanned, and then continue scanning. Rapid Recover System: If a paper jam occurs when the "Rapid Recover System" is enabled in the ISIS/TWAIN driver settings, the image of the document is not saved, and scanning stops. You can continue scanning from the document that caused the paper jam after fixing the issue. Additional Considerations: Make sure the pickup rollers retract when the machine is powered on. Check that the stopper plates are in the down position. Verify that the upper unit is completely closed after clearing the jam. Remember to handle the scanner components carefully to avoid damage. If the issue persists, consider seeking professional assistance or contacting Canon support for further guidance

I would use a soft toothbrush and a little Isopropyl Alcohol and then a lint free cloth and then give another gentle brush. There are some other ideas here. Take no notice of the answer by 'Marvin' on Fixya about dropping the head in boiling water, I think he thinks he is dealing with a colour inkjet printer. https://www.google.com/search?q=canon+p23-dh+v+printing+calculator+clean+print+head ..
