Subject: [Homebrew_PCBs] Toner refills

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

I have used toner from,

http://www.tonerrefillkits.com/

with HP1320 and HP1102W printers. My experience is  that there is no difference between the OEM toner and their refills for PCB transfers.
