Hi Jim,If .086 PLUS the .010 carrier works, then .062 should go through, if the ribs are cut off. I might have to get another E260 and try it. I just bought a "dead" E250 to see if it can be modified. I paid about $25 for it. I think it will work, but I have to get a drum and toner cart for it.I have two E260s that have been modified exactly the same. Using the same toner/drum, 1 gives perfect images, while the other has skipped areas on the same pcb. <sigh>.MarkAt 04:07 PM 8/5/2014, you wrote:
Hi MarkVery good write up on your modification of the LexMark 260The last communication we had was about the maximum carrier thicknessplus PCB thickness.I was running a 0.062 PCB without a carrier and the printing wasstopping at about half way through. That was caused by the PCB being tooshort and the ground pulling off the PCB as it was half way through theprinter. Putting the PCB on a 0.010 card stock carrier that was about 12inches long cleared that up. (using a small wire soldered to the PCB andattached to some copper tape at the trailing end of the carrier. then apaper clip connection to ground.)Today I preformed an experiment to determine the MAX thickness thatwould go through the printer. I took a stack of 0.012 card stock sheetsand stacked them to make an overall thickness of about 0.062 inches. Ididn't include a PCB ... just printed on the card stock.0.062 ... ok0.074 ... ok0.086 ... ok0.098 ... jammedso it looks like a carrier plus PCB thickness of 0.086 is my limit.Also your extra effort to remove the paper platform is neccessary forthicker PCBs.Note: the paper platform has not been removed in my modification but the"ribs" and "bumps" on the paper platform has been shaved off using asharp chisel.Jim KI6MZ------------------------------------Posted by: Jim <jhutch17@...>------------------------------------Be sure to visit the group home and check for new Links, Files, and Photos:http://groups.yahoo.com/group/Homebrew_PCBs------------------------------------Yahoo Groups Links
