Toner refills
2015-04-02 by Robert Nickels
Like most of us I suspect, I make PC boards using the toner transfer method. I have an HP Laserjet 5000 which is an office-grade printer capable of up to 11" by 17", which is nice, but my toner transfers have been of marginal quality. There's no problem in getting the transfer to work, but the amount of toner that is transferred seems inadequate. Before etching, the black areas where toner is present appears mottled and not solid black, with tiny pinholes visible. Even though I use the green film, the copper is rough after etching, traces are undercut and of inconsistent width. I've already got my printer maxxed-out as far as settings go. I use the Pulsar transfer paper, and they advise that my problems are due to using refilled toner cartridges which don't contain enough or the right kind of materials. Even though the output looks fine on paper I can accept this, but the refilled cartridges are a small fraction of the cost of new HP brand toner cartridges (e.g. HP 29X which sells for $235). My question is: are there any recommended alternatives which would give me better results at a cost somewhere between the bargain refills and the new HP 29X? Thanks and 73, Bob W9RAN
