Modification of the Pantum 2502W for Direct Laser Printing of Printer Circuit Boards
Hi! Can't find model 2502 but 2500 is available, is it suitable for this project? Thanks!
Modification of the Lexmark E260 Laser Printer for Direct Laser Printing of Double Sided Printed Circuit Boards
Thank you, my first step is on your first remote rcall: set_ports:"ldi rmp0, 0x16 ; 0 in, rest out"It should be 0 and 3 input. 1, 2 and 4 output.Is that correct ?"ldi rmp0, 0xFE ; outputs high, input pullup on"It does mean: Outputs high, input port4 pullup on, input port0 no pullup.pis has pullup resistor.npis does not have pullup resistor.Is that correct ?Please don't worry, I need an initial good understanding.
The code is very simple, and an Arduino could certainly do it. The timing is explained in the comments in the code.
Great job Mark Lerman !It is a very usefull printer. I would love to modify one for me. I am seriouly thinking on doing that.I'm not a very experienced Arduino programmer but I think I could write an Arduino version of that MCU code. It seems to deal with some timers and monitoring some digital sensors.Do you have a pseudo-code, or fluxogram ?firstname.lastname@example.org

Sorry for the lateness of this reply - I was away. I have not tried ds boards with the Pantum, but something like I did with the E260<http://www.instructables.com/id/Modification-of-th...>would probably work reasonably well.
Well, I have sold some from time to time, as well as completely modified printers and some parts, but more as a service than a business. Are you interested in one? Sorry for the lateness of this reply-I was away.
mlerman,Have you made any progress towards double sided boards? Do you have any advice with how to do it?Thanks again!
I notice you seem to print the MCU board a lot.... Are you selling them?ThanksTom
Hi Roland,The only laser printers that I know won't print to copper are the HP ones. If you can get the service manual (not the user manual), that is a big help in doing any conversion.What I have done is attach a simple data logger (e.g. one of the Dataq ones) to the various sensors, then run a print to get the timing as the paper moves through the printer. You also have to be able to make a flat path through the printer since carriers and pcbs are not as flexible as paper.The Lexmark E260 and the Pantum 2502 are very different. The Pantum actually prints as the paper goes up the back of the printer. Many of the inexpensive printers print this way, and they have the least number of sensors you have to emulate. In fact, the Pantum has only 1 sensor. It also has one solenoid that is activated when the printer is about to print.The E260 prints as the paper goes from the front to the back of the printer. It also has a manual feed slot that I use to feed the pcb. This printer has a lot more sensors that need to be emulated.Not sure if this helps. One suggestion is to buy a couple of cheap used printers of the same type and start experimenting with the thought of probably destroying one as you learn.Good Luck!
Do you think it is possible to convert a "Ricoh SP 112" I know you don't know the inside, but still, what are your thoughts?
Hi MlermanI really liked your Instructable, and I can't wait for future improvements. Thank you so mutch for this amount of work, and effort.Unfortunately I can't get this printer, nor the Lexmark E260 in Hungary.Can you help me what should I take care of, and what kind of printer shall I buy to be able to convert it, and could you give me a generic method of converting a printer.I am curious about the steps not listed above like recording the sensors data, and so on.Thanks
Hi, I just picked up the Pantum, and will start working on this project over the next couple of weeks. I also have a 3-D printer, so I intend to 3-D print some of the components to see how they work. I'll try to print a stand you can set the printer on, so you don't have to worry about the cables as much. Thanks so much for doing this. I look forward giving it a go
Would a lexmark e232 work. How much different would the timming programe need to be?
Mark, I made it... once again thank you for sharing... armorer, thanks for sharing your problems, I had also hole in carrier not in ired light, but seeing your comment I realised immediately where is the problem( the printer stops with error led) other things - I was too lazy to clean pcb good enough... so to all the others - it's important... oh yes, one more thing, as you see in comments, dont forget to set fuses on attiny to get proper clock... I had to change clock to 9,6 from default 4,8. prescaler was already default set to /8cheers, Rafał
Just a question regarding attiny clock - internal RC oscilator running at 4,8MHz is OK ?
armorer 243 - congratulations to you. Anything you could add to this article to make it easier (something was unclear ? ) ?printer , materials ordered... next week it will be clear if I have my own direct pcb printer or I have new few kilograms of waste :)ok, seriously now - before I start and even see the printer - tell me please if the pcb during printing TOUCHES the roller with "pcb picture"? or there should be a thin gap?one more triggered by armorer243 - normally in hex file fuses settings are already in. so I assume in this one we have them too... just load the hex and attiny should be ready to go, right? also seeing comment about carrier thickness - is there any reason behind aluminum as a material for carrier? can I use stainless steel sheet 0,2mm thickness?
impressive, really really... :)just went thru polish similar to ebay site (allegro dot pl)and realised taht somehow pantum 2502W is not here, but very cheap is model 2500. looks similar, this is no wifi model. please have a look on this model. does it looks that it wil be VERY similar, or you alredy see a significant difference...
This is so amazing hack! In hindsight "Oh, so simple", but truly amazing :) I just purchased a laser printer on ebay and will be gutting it next weekend.Take that Rapid Prototypers and good night dreams of routed PCBs! Just click "Print". I'm loving it already :)
