Checking Paper Status, Pick-up Roller, Feed Roller, and Friction Roller for 1st Feed Tray
Check the paper position (Check whether or not the leading edge of the paper, side paper guide, and end paper guide are positioned according to the manual.) |
|
Check if the paper has reached the maximum stackable limit of the side paper guide. | Reduce the paper to below the stackable limit. |
Check if the sheets are stuck to each other due to edge roughness, coating, stain, or temperature. | Fan the paper. |
Check if extra thin paper or thick paper exceeding the supported paper thickness is being used. | Use supported paper types. |
Check if the paper thickness and size are detected correctly. | Set the paper thickness and size to the correct value. |
Check if the paper being used produces a lot of paper dust. | Change the paper type (if possible). |
Check if the paper feed tray is not stained with paper dust. | Clean the paper feed tray. |
Check if the paper roller is not stained with paper dust. | Clean the pick-up roller, feed roller, and friction roller for 1st feed tray. |
