Can You Help me Please

There's a plastic flag that goes through an optical gate and tells the printer that the output tray is full. The flag is stuck, broken or missing, or the optical sensor is dirty. Search for the flag at the level where the paper would be if the tray is full.

any sensor displace please check cassete paper sensor.

Cassette sensor switch inside the machine body. Remove cassette outside and check machine body bottom where cassette is installed. Switch Has been misalignment by unfortunately. Align this two Switch Sensor Then again install cassette. Hope its working.....

Look carefully on the left hand side. All the paper from those trays pass up the left. ( you probably know that) The last time I worked on one of those machines paper feeding up from those trays can get stuck you've got to investigate where the paper is stuck coming up from the trays. Open the left door and very carefully see how far the media has traveled, does the lead edge get damaged, dented or spoiled in any way. ( look closely there) don't just rip out the paper, investigate why. Just how far has the media moved from the tray selected. I suspect a torn bit of paper stuck inside. If your machine is difficult to get to you must make room to look properly with a torch if necessary. Pull out trays 1 & 2 fully so you can look without being hindered. Good look!

if this were your problem it would be obvious the inner tray is in the middle of the machine there is a lever that lifts up as paper stacks up its probably stuck in raised position

Remove the paper tray. Lift the printer and you have to see paper feed roller it is rubber, just clean of dirt with cloth and alcohol or water.
