If you see an “unknown accessory detected near you” message (or similar), it means there`s an item compatible with the Find My network that might be traveling with you. If so, its owner may be able to see your location. You should look to see if something you`re borrowing has such a device attached.
Quick fix. Error code e02 occurs due to overheating of the printhead or when the paper is not correctly placed into the input tray and therefore the paper feed rollers are unable to pick up the paper from the paper tray.
Solution. Error 2 is a network error code produced by Windows NT that generically translates to: “The system cannot find the file specified.”
If your printer`s status displays “Printer in error state,” there may be a problem with the printer itself. Make sure the printer is turned on and connected to your PC by Wi-Fi or cable. Check it for low paper or ink, and be sure the cover isn`t open and the paper isn`t jammed.
Most printers will stop working when they`re out of paper, ink or toner, or if the unit detects an issue with the ink or toner cartridge. When this occurs, you might receive an error message or notice blinking green or amber lights on your printer.
Ghost printers are printers that continue to appear in Windows although they have not been used or installed on your system in a long time, which may have been years.
Open Settings -> Devices -> Printers and Scanners (or run a quick access URI command: ms-settings:printers ); Select a printer you want to remove and click Remove Device; Confirm the printer removal.
The problem of the printer icon not displaying in devices & Printers is frequently resolved by downloading and installing the most recent printer driver. If your printer drivers are out of sync, they may not function until you download and install the latest update.

ANSWER : I would suspect the fixing film has wear. You can prove the theory by doing a half-stop test. This stops the print before it enters the fixing film assembly. Load paper in the drop down MF tray in the front. Send a print job and when the tail end starts to enter, open the cartridge lid on top to stop it. Then remove the toner cartridge and look at the paper. If you see the marks, it is from the toner cartridge. If you don’t, it would be coming from the fixing film since the paper hasn’t entered it.
