Black Smudges from Tray 1 MPT

Dust, dirt, toner, in paper path, clean. This paper hits portions of the printer diff. than 20lb and grabs toner where thinner paper does not. -Carl

Your lower trays are programmed incorrectly. Change the size and or the paper type back to letter and plain paper

ok seems like 1 of 2 things,,, firstly check your print settings and ensure your selecting the correct try to print from..


turn off machine

might be a stuck sensor, turn off machine look at where u load the paper, close to where the printer pulls it up, there is a small leaf swith there that tell the printer if it has or dont have paper, play ith the switch a bit.. Then turn back on and try again.

The printer trays accommodate most sizes and types of paper, transparencies, or other
specialty media. Follow these guidelines when loading paper and media in the trays:
- Envelopes, labels, and glossy paper can be printed from Tray 1 (MPT) only.
- Transparencies and custom size paper can be printed from Tray 1 (MPT) and Tray 2.
- Fan paper, transparencies, and labels prior to loading them in the tray.
- Use only paper envelopes. All envelopes should be printed single-sided only. Some
wrinkling and embossing may occur when printing envelopes.
- Do not overload the paper trays.
- Adjust the paper guides to fit the paper size.
- If excessive jams occur, use paper or other media from a new package.

It's hard to set up the mpt tray when the display is out. Send the job to the printer with no paper in the mpt. The printer should then ask you to put 11 x 17 in the mpt. Hope that helps.

125: Error

Error detected in MT home position.

1) is an Error Message displayed? Yes

Turn ON power again.

2)Does the Error take place again? yes

Replace MT

This error means there is an open circuit in the Paper size sensor, in Tray 1/MPT.

It could be a broken wire in the tray assembly, or a fault on the Engine control interface board.

The voltage at the sensor should be about 3 VDC. (Pin 1 of Plug J610)

If the ghost is black then you might have a bad Black Developer 116-2011-00

If the ghost is in all colors then it may be your fuser, or possibly just your paper settings. (If you are using glossy paper or card stock this needs to be fed from the MPT tray and defined correctly in the control panel)

Good luck!

Very nice trouble shooting. The image defect you describe point to the OPC or drum unit this is essentially the toner cart. In your case black. Measureing the distance between repetitive defects is a sure way of diagnosing problems such as yours. Again nice work.

Google repetitive defect ruler for your model to help in the future.

Hope this helps
