Error code 6500


"The 6500 error code is a logic board error code. The PCI Bus error is detected by the ASCI. Sounds like it needs new logic board. but i suggest you reset your printer - 1. Turn the printer off with the Power button (if available).
2. Disconnect the data cable from the printer.
3. Unplug the printer's power cord for approximately 10 minutes, and then plug it back in.
4. Turn the printer back on. If this works you're done, if not try the next step.
1. After confirming that the printer is powered on, open the paper output tray.
2. Open the top cover and wait until the print head moves to the center.
3. Open the inner cover and check that ink tanks are properly seated.
4. Properly seated
5. Press down on each ink tank until a click is heard.
6. Close the inner cover and top cover.

If I could be of further assistance, let me know. If this helps or solves the issue, please rate it and give a testimonial for my response
Thanks, Joe

Open heat error


Open heat error is a fuser error. If you have plenty of clearance around the printer and you are still getting this error, it is the fuser.

• At the warm-up stage, the heating roller
thermistor/3 voltage does not decrease by
predetermined steps (temperature rise)
within a predetermined time.

Check the fusing unit for correct installation
(whether it is secured in position).

Check the open/close operation of the
upper right door.

Check the fusing unit, IHPU, PRCB and
REDB for proper connection and correct or
change as necessary.

If that check still give you error code 3921

Change fusing unit

It sounds like the fuser rollers are not at the proper temperature to work.

They should be inspected by a technician.

That is a fuser realted issue. Not warming up properly.
Most likely a defective fuser. The over heat has opened, the heat element has gone bad.
Fuser more then likely needs replaced
