Canon MX330 paper output slot has paper jam error. How to clean sensor


I just solve the problem and it's pretty simple. Just turn off the printer and put paper on the printer, then you turn it on and make sure the paper goes out from the other side; and done the warning message disappear (if the paper don't go inside the printer force it to go inside).

  3. The media input tray might be too full. Remove some of the sheets.
  4. Make sure that the media being used meets specifications. Click here to refer to "Media specifications" for more information .

  8. The paper might not have been removed from the main input tray before the tray was refilled. Always remove paper form the main input tray before refilling it.
  9. Output capacity might have been exceeded in the paper output bin. Do not allow more than 125 sheets of 20-lb (75 g/m2) bond weight paper to fill the paper output bin (less for heavier paper).
  10. The pickup roller or printer separation pad might be dirty or damaged. Clean or replace the part. (See the product user guide for information about cleaning and replacing the pickup roller and printer separation pad.)

PAPER JAM


Look for a "jam door" at the rear of your printer (if so equipped).

You will need : 1 can of "compressed air", 1 container of ether rubbing alcohol or some form of Goo-Gone.

1. In short blasts (NOT LONG ONES) blow through the paper path. Open any paper jam access trays before doing this so the bits escape.

2. Using a SMALL amount of Goo-Gone and either a Q-Tip or small dust free cloth, clean all the rubber rollers on the bars. Cheap paper leaves a fine dust and after time will make the wheels very slick.

Doing this every other month can save you from jams and is just a good maintenance plan for your printer.

Also don't use 'cheap paper'.

Good luck! :)
