Epson WF-3640 Chipless Conversion: Send Your Mainboard, Formatter Board, Motherboard

Due to popular demand, we have a long waitlist (usually 2-4 weeks). Please be mindful that we cannot work on your mainboard as soon as it arrives.  You are welcome to send the mainboard here but it will be a few weeks until we can work on it.  Please check here for our current waitlist (BCH Waitlist).

Can we do it online without sending the printer or mainboard?

• Maybe. It depends on your computer skills. See the video below.

What is this "Mainboard Repair Service"?

• This service is for people who can take the mainboard off and send it to us. If you want to send a full printer, then use the other services. If we receive anything more than a mainboard, there will be extra charge for it. If you are local, you can bring the printer here if your printer's serial number is less than SEYYB5xxx. For example, SEYYA, SEYYB4, are probably going to work... but not SEYYCxxx. We can do a quick test and see if we can do it outside of the printer. If we can't, there is a $50 charge for us to take the mainboard out.
• As far as we know, there isn't other company provide the chipless conversion for WF-3640. You have to do it on the mainboard. Therefore, you send it in, we modified it into chipless and send it back. However, you need to turn off the automatic firmware on your printer. Otherwise, you need to send in the board again. If you don't know how to turn off the update, see it here: https://bchtechnologies.com/how-to-disable-epson-automatic-update/
• There is always a waiting list. So please get in touch with us before sending your mainboard in.
• We are not liable for possible damage during the shipment or repair or any loss during shipment. In addition, for all the repairs, the printer is deemed at NO VALUE. Therefore, we are not susceptible to any risks by accepting this order.

Small Prints:

• We do not guarantee that the printer can be fixed.
• The printer is considered NO VALUE and NOT WORKING if you order this service. If the printer is damaged or lost during transportation, repair, or other circumstances, there is no compensation.
• Once the work is completed, we will send you an email with a Paypal invoice for the return shipping. You have seven calendar days to pick up or pay the invoice to remove the printer from our workspace. We will give Triad Electronic Recycle Center the printer after seven calendar days.
• The above seven calendar day starts when we SEND the email. It doesn't matter if your spam filter catches the email, doesn't read the email, doesn't reply to it, is on vacation, or gives birth to a child. We have so many people who just disappeared after telling them the printer couldn't be fixed. We have to clear out the space and get things moving.
