Question about Epson ACULASER CX11NF All-In-One Printer
Paper jams coming off tray. Pickup "wheel" initially engages ok, picks up paper ok, then goes 95% of the way around (moving the paper like it should), but gets stuck on the last little hump to reset itself back to normal position, thereby not fully pushing the paper far enough and jamming the paper, and vibrating the pickup "wheel" so it sounds like a mini jackhammer. I you reach in the tray area and manually push the pickup "wheel" around the extra little notch by hand, the paper goes through fine, and the machine is fine until the next sheet gets loaded, and then the same thing happens.
I suggest you get a sheet of Card Stock (Heavy
paper) and place it in the feed way. Then press the print
button applying a slight amount of pressure on the Card Stock so it
will feed through the printer. The reason for this is in some cases I
have been able to clear the paper track of debris that was deposited there
Worth a try, as I have fixed a number of printers this way, saving costly repairs.
Hope this helps. Bud
