The foam on the new solenoid is not sticky? All gears are in their proper place on that side of the assembly?
On that series, that error is a jam/feed error.
Typical troubleshooting procedures for that include:
- Turn off the printer completely: Unplug the power cord from the wall outlet and wait a minute.
- Check for paper jams:
- Carefully remove any jammed paper from the printer's input tray, output tray, and any other accessible areas.
- Inspect the registration assembly area for any debris or obstructions.
- Reseat the ITB (Image Transfer Belt):
- Locate the ITB within the printer.
- Carefully remove the ITB and then reinsert it, ensuring it's properly seated.
If all that fails, maybe one of the paper jam sensors has gone bad.
