After 17 years as a photocopier technician, I never knew that acetone vapours would fix toner.
As for the alignment, the rollers are designed to feed the paper just a bit cause a slight buckle in the paper, forcing the paper the be straight across the first set of rollers.
Since you cannot buckle the copper clad board you cannot ensure that it is evenly aligned every time.
there is a better method. I use A4 Paper with a gum coating (like post stamp). Then i print on the gum side and transfer with a modified laminator. solved all the problems you mentioned. also double side no problem and no changes on printer needed. only put into water and the paper come off with no force.
Hello, tanks for the creative idea. as you already have done few experiments on other brands but although just like to ask you that if the same is possible with epson laser printer
What??? You didn't make a cnc machine to just route out the .001mm copper? just kidding, this is awesome,
I was thinking exactly this after dozens of failures of toner xfer, why can't I just print right to the copper??
I haven't taken apart a printer, but I assumed the paper must roll past the laser curved around, so a solid sheet would not work,
is that why you must strench the image? ok this was 6 years ago, you have made the cnc machine now right? 🙂
BIG FAT WARNING! I just read the instructable and it recommended a shop vacuum for cleaning up toner dust.
NEVER do this unless you are sure that the vacuum has an anti-static hose.
I once witnessed a colleague blowing his office windows out with a toner dust explosion after using an ordinary vacuum to clean a laser printer. Fragments of glass and plastic were embedded in the ceiling tiles and he came within an inch of losing an eye.
Such a relaxing voice. Watched it twice just for the Asmr

hello anyone here…?
I wonder if you could round over the edges of the PCB with a file or sander to prevent scoring the roller?
I cannot tell from the shots but how can a PCB sheet pass through a printer without jamming up. You would normally only be able to print on (at most) a thick card or envelopes.
Pro tip from someone covered in this toner for years: I recommend you keep the foam from the toner cartridge. NOTHING cleans up toner better than that foam.
how did you modify your printer???
Thank you very much.
Rearranging printer roller with Alumina rollers is a good way but chromium rollers work best for dyes and also engraved PCB works very effective rather than the emboss PCB. The printer looks good though.
wow
Hello, please provide us with an address that sells this printer. You can email us on the phone 964 + 7901239474 There is a Viber and there is a WhatsApp or email us at ayadnoorei@ymail.com
Good idea sir. Hardware Changes video share please Thank you ?
Super , new information
i disliked this video because you talk slow and sad if you keep doing it i will unsuscribe too
well if you have to wait half an our for the toner to get hard, i think you might aswell use an iron. personally i'm just thinking of getting a small flocking heat transfer press for transfers
you can shake some powder coat on top of the laser toner,blow out the surplus, and then put it in the oven. It will give you a nice thick surface for protection and it will keep the dimensions of the toner
What's your printer
Sssssssssssssseven segment display clock
Thank you very very much for your display
Hello, I'm thinking about a fancy way to avoid the acetone part.. What if you use the pcb copper layer as a resistor, applying some current to it, in order to make it warm and dry the ink?
It's a nice project, I think that with some tuning you will achieve a correct result.
Probably if the printer firmware was open source, then with some modifications, and adding more sensors would result in a perfect print on the pcb.
Maybe you can add some rollers at least to protect the toner from those scratches… They don't look very good!
I don't know the laser print process, but maybe is not the most indicated… Think about an inkjet, modified to use a thicker ink, more like paint, that will dry in minutes… I think that it will be less sensible than laser.
I have seen printers modified, in order to be used with clothing, is not an unusual thing.. Maybe some printers are more indicated, or have a firmware that it's more suitable than the others!
Are you sleepe?
Just heating printed PCB with an iron or with a soldering fan works well without the acetone.
I did NOT see the dickbutt coming haha
I have had nothing but good luck with toner transfer.
Aluminium
So this is just a regular office printer and its normal toner cartridge?
mate, your projects are amazing!
Just give me a call please
What would you charge if I seen you somewhere work you contact me 8643093399
Seriously 😮
Your voice reminds me of professor Snape for some reason
Great video. I really like your method. (I only came across your video now and see it was already posted approx 3 years ago ) I use the Photoresist method (Positive 20) with various odd tricks & am happy with my results. I appreciate how much work it took to convert your printer. I hope by now you have solved the problem of the damage to the photoconductor roll.
dick buttttt
this is a comment.
Toner Transfer ist much easier. No need to modify printer, just a suitable catalog page and a laminator. Works down to .2mm no problems.
How EleksMaker® EleksLaser-A3 Pro 2500mW Laser Engraving Machine CNC Laser Printer works? Could you explain please.
circuit on pcb : )
the main disadvantage is the additional time for binding with the acetone, what is you main problem with the toner transfer method?
I mean printing on paper and transfer to the metal isusually takes less than 1-2 minutes.
I figured out when i started that my toner does not work with isoalcohol, and acetone disolves to fast (1-5 sec) so its unusable (even mixed with iso). Through experiments i found a better solvent: Xylene sold in Germany as "Universal Paint Thinner or Nitrothinner".
Tro be sure look on the ingredients of the can.
I found out that for my toner the best mixture is 75% isoalcohol +25 Xylene.
Its because there is enough Solvent (Xylene) and enough time to work with (doesnt evaporate instantly like with the actone i tried).
Ah , there is one caviar, instead of normal paper i have to use magazine paper (doesn't matter if it has already color on it.) i use the Paper from the IKEA Kataloge i got for free :).
Main reason i took that experimenting hassle is i wanted to elektro-etch a logo on a knife.

Get extremely thin PCB material.
That will stop the damage to the drum and conform to the flatness of the drum.
You can then make as many layers as you like, stack them and plate the holes.
Very good work… No need to use acitone.. apply heat.. in toster oven
Great video, I use the old iron on method with the iron set to medium. Before I start to iron I spray some silicone spay on a rage , then I iron the rag to transfer the silicone onto the iron. this makes the iron very slippery and prevents smudging. I have used this method for years and seems to work very well.
With all these downsides, I just don't see the benefit over laser printing on tracing paper, applying a bit of oil and exposing the board. This works great for me and I find the exposing the most relaxing part of the process, while the etching takes most time, preparation and cleanup. Also Acetone and Toner dust are are recepie for cancer.
Have you tried transparency film and photoetching? Or direct laser imaging onto photoresist (like a laser projector imaging the photoresist coated PCB) ?
