  • Modification of the Lexmark E260 Laser Printer for Direct Laser Printing of Double Sided Printed Circuit Boards

    Could you send me a picture of your problem ground planes? How large a pcb are you printing? You can send me a jpg directly at mlerman@ix.netcom.com

  • Modification of the Lexmark E260 for Direct Laser Printing of Printed Circuit Boards

    Yes, heat would work just fine. For me, it's a bit easier to use the acetone. Especially for a 2 sided board where I just hang it suspended in a tall closed container with a half inch of acetone in the bottom. When I'm done, I just air dry the pcb for a few seconds and pour the acetone back in it's can.

    The code is very simple, and an Arduino could certainly do it. The timing is explained in the comments in the code.

  • Modification of the Pantum 2502W for Direct Laser Printing of Printer Circuit Boards

    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.

  • Modification of the Pantum 2502W for Direct Laser Printing of Printer Circuit Boards

    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 acti...see more »Hi Roland,The only laser printers that I know won't print to copper are the HP ones.

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!
