Question about Epson TM-U220 Matrix Printer

Open Question

We had a bank wide power outage and now several of our validators will not print. The error we get is "Error number -2147221398 occured while trying to access the validation printer. The error is described as 'There was an error writing to the validator." We have tried reseting the validators through our teller software and turning them on and off and also restarting the computers. It is happening on multiple teller computers, however some are not effected at all. Email me at Thanks !

SOURCE: Printer Error-->

I just moved to Alaska and shipped this printer up and had the same problem. What I found was that when I start up the printer, the carrier that holds the printer cartridges would not move all the way to right side of the tray. You can see this if you open up the top portion of the scanner glass carrier.

Turn off the power and remove the electrical plug from the back of the printer to be sure no power is feeding the printer.

If you closed the top of the printer, the part where the scanner / copier glass is at, open it back up.

Reach into the printer and manually move the piece of plastic that holds the print cartridges to the left.

Directly underneath where the print cartridge carrier defaults to on the right hand side of the printer you will see a piece of white plastic on the bottom. It will probably be sticking up. It is hinged. Push it down gently so that it rests down inside of the indention where it is supposed to be.

Plug your printer back in and turn it on. The printer will go through its self test, and if this was the problem will work correctly for you.

Sorry to say that there isn't currently a confirmed reset utility available on any of the usual sites...

The only POSSIBLE option I found that MIGHT work is the CX5600/DX4400 adjustment utility from 2manuals

Best of luck and hope you find a usable solution.

Usually with this error the program checksum for the printer controller is corrupt or the data controller memory is corrupted.

You can try redownloading the program into the printer or it's possible it also has bad Flash Memory.

Unable to use the oven since the power outage...two codes appear on the display--e1 f1......tried to reset but no luck.


Error code F1-E1 means that an error with the keypad has occurred. Usually it happens due to loose ribbon cable on the keypad or the electronic control assembly itself going bad. To resolve this issue first, disconnect the power to unit and then gain access to the back of the clock assembly (Electronic Range Control/ERC). Now unplug the touch pad ribbon connector from the ERC, it would be a flat wire approx. 1 1/2" to 2" wide and make sure that the cable is not broken and nothing is shorted on the keypad. After this is done insert the cable back and then plug the unit back to check. If the error is still there then the electronic control board should be replaced. Hope this helps...please post back for further assistance.

A Brother MFC-8840D reported an Error 6A on the panel after a short power-outage that occurred. Calling Brother indicated that the error reflects that.

To clear the error, the procedure is as follows:
1. Turn off printer
2. Hold down MENU button on front panel and turn on power while continuing to hold.
3. Release button after 5 seconds (after the Please Wait message)
4. If error still occurs:
5. Press 91
6. If error still occurs:
7. Press 99

This should clear the error.

Good luck

What does error code 3501 and 3502 mean on advent AWP10 printer

Printer error code "3501" occurs right before a print job. A flashing screen will tell you that the printer cannot print due to error code "3501". These error codes are generally experienced when you use diagnostic sheet to print and change the ink over them. This error code could also indicate that buffer length of a print was not valid.

KDF70XBR950 red power light belinks 6 times repeatedly


You have a power board error, and TV is in protect mode. This had been caused by the power surges.

Try leaving the TV disconnected from power (unplug cord) for several hours, or overnight.
This will allow PSU capacitors full discharge and can fix PSU fault after power surge. If it does not correct the problem , then there is a faulty component.
In that case the TV must be tested and repaired by a technician.

Xerox 8550 printer has error or fault code 37,018:45:24719

Oh yuck. That is a source voltage fault.
The electronics module has most likely failed. Umm very expensive also. See if your insurance will cover repairing it. That way you can have Xerox come in fix it and insurance reimburse you. I have had to do calls like this several times and have had insurance pick it up. You may need an estimate to repair from the insurance company.

Whats error code 3501

According to Kodak, that error just means the cover was open. I noticed when I print a diagnostic sheet that error shows up whenever I change the ink.

Trouble printing a thicker form

I have come accross this problem on a number of sites. It may be the Paper Out sensor. It works by emitting light from one half of the sensor reflectiong it of the paer and picking it up with the other half of the sensor. When no paper is present, the light cannot reflect and hense a paper out error is reported. I have seen this error occur when paper with dark backing ( like that for bank and tax forms ) is used.
