Epson 4900 Cassette Tray Paper Feed Problem
« on: January 02, 2014, 02:10:30 pm »

We have an Epson 4900 that won't feed papers through the cassette paper tray. It says there is a jam and to reinsert the cassette tray even though nothing is apparently wrong. We cleaned the paper path and checked to make sure it was clear, but it continues to ask us to reinsert the cassette tray. This happens with multiple types of papers in various thicknesses. Going through the top manual feed or roll feed has no issues/problems. Any suggestions before we contact Epson?

Thanks!

So the alert is immediately after inserting the tray?  Maybe a sensor for the tray is damaged or covered?

My experience may or may not apply: Our original 4900 was replaced with a refurb machine after a head failure, Our original machine never showed paper path problems. The refurb's cassette path quickly showed trouble, with sheets either never leaving the tray during a print cycle, or sheets being picked up from the tray but jamming the path early after making the hairpin bend. Replacing the pickup roller made no difference; ultimately a new paper cassette did solve the problem.

What was happening, we learned, was that the cassette "rear hinged door" was hanging and would either never drop down (like a draw bridge does) or it would "reluctantly" drop only after deforming the leading edge of the sheets. It was the sheet deformation that caused jams; and when the door never fell at all, the paper of course never entered the path.

Short of replacing the your cassette tray, look at the cassette's rear door and see if there are any observable reasons that door would not fall. Also shine a flashlight into to rear of cassette (with it in place and paper loaded) during a print cycle, and watch the behavior of the pickup roller and the cassette door. There may be some diagnostic clues there.

Good luck,
