EPSON WF-3720 vs EPSON WF-3720DWF
I want to bring to your attention these two printer versions of the same model:
For different regions in the world (maybe the difference in the PSU 110V one and 240V the other)
One is EPSON WF-3720
And the other one is EPSON WF-3720DWF
User Guides and Cartridge Models
I see that EPSON only has one user guide manual for both that is the one for WF-3720
I also noticed the different cartridge model they use:
WF-3720 uses EPSON 702/702XL cartridges (eg. T702XL)
WF-3720DWF uses EPSON 34/34XL cartridges (eg. T3471)
Chipless Firmware Update
Please if someone can confirm that chipless firmware available for WF-3720 as found on chiplesssolutions.com is also working for WF-3720DWF?
The firmware for these models is common
The chipless firmware update was successful.
Tips for WF-3720DWF
- This Epson printer (WF-3720DWF) (non-US model DWF) can NOT be brought to software update mode by pressing power + top-right of the screen.
- If you have firmware newer than CL26H9 - this is firmware compatible with chipless key - then you can bring your WF-3720DWF printer to ROM recovery by official Epson app:
1. Make a normal firmware update using Epson updater
2. Use USB cable to make the update
3. During the firmware transfer (re-flash the same version) disconnect the USB cable (try this at various points during the transfer)
4. The ROM will become bricked and next time you start the printer (force shutdown by unplugging AC) it will be forced to start into ROM recovery mode
5. Now you can flash any firmware version you want via USB (including chipless-compatible) and this is the only way to downgrade WF-3720DWF (if needed)
Cost and Savings
- I just want to thank chipless for their effort because the cartridges are VERY expensive for this model WF-3720DWF, close to the price of an entire new printer.
- Printer cost (brand new) was $140
- WF-3720DWF uses EPSON 34/34XL cartridges that cost $99 per pack (XL) and will last only one week in a normal/small office!!!
- Do you want to pay $400/mo for WF-3720DWF OEM EPSON inks in you small office?
- Or do you want to pay $240/mo for WF-3720DWF aftermarket XL ink cartridges ($60/XL pack)?
- Seriously Epson is crazy with these prices, ripping small businesses off big time!
US Version Compatibility
- I have a US version WorkForce Pro WF-3720 that does not go into firmware update mode by pressing the power button and the top right corner of the screen. Would the steps you described for the WF-3720DWF work on the US version WF-3720?
- yes it work , im already tested by myself, but i dont know why i canВґt pay for the chipless firmware with PayPal
Program Update Mode
- Please read here how to put WF3720 into Program Update mode - https://www.2manuals.com/forum/index.php?/topic/80506-how-to-put-wf-3720-in-program-update-mode/
- You have to press on another place on the touchscreen
