Laser printer

ISTR that is usuallly either running out of toner or a duff/dirty corona wire.

Somewhere there is an ace site that deals with laser issues.

Tried tilting the cartridge on each end a few times?

It's not showing a low toner warning. And the results are quite even - just grey rather than black. However, it is a replacement non genuine toner assembly, bought from Ebay.

I've tried it from both the Acorn and PC with the same results. I'm not well up on lasers - should it give as 'deep' a black as my inkjet?

I'm attempting to print to an iron on transfer paper for PCB making. But given the cost, want to make sure it's printing properly on paper first.

Don`t need expensive transfer papers, glossy magazine paper works with a bit of experimentation;

My cheap Samsung has a "toner save" setting, but it doesn't make that much difference.

I'm using a cheapo Ebay replacement cartridge with no problems.

I was more meaning the density of the colour. The crispness isn't so important for what I'm doing.

It's just standard cheap general purpose paper.

Yes - I've tried the old one. No difference.

Not with photo glossy but with magazine paper, thicker seemed better, seem to remember Rapid flyers were actually pretty good..

Bit of pinholing and odd missed bit, some touch up required with marker pen

Laser Star and trans or whatever, seemed to work about as well as glossy paper...

Now looking at milling PCBs myself ;-)

Insufficient toner is being transferred, defective OPC (organic photo receptor drum). It could be incorrect toner, samsung are known to be quite fussy.

Ask the seller, because the buck stops with them.

Laser printer makers are falling over themselves to make compatibles as difficult as possible, printers as cheap as possible, and consumables as fantastically expensive as possible. At the low end. Flash updates stuffing compatibles too.

So the original does the same... ... some of the small Samsung have rather "thin" text, lack density and depth to the black. Particularly the cheap LED units from owning a few over the years (such that I prefer the soaked-in deeper black of inkjet surprisingly).

The new ultra-fine toners give a very thin & crisp image, not actually as pleasant as the deep solid layered black of 300dpi lasers of long ago.

Have you tried turning the dpi down?

If you're doing anything fine-ish (eg surface mount), don't bother. You can get better resolution from a bad etch of a poorly exposed bit of OHP film printed on by a 1980s laser. The only useful thing about a milling machine is that it can drill the holes for you, but you don't need so many holes these days as you once did.

^this OHP film in a HP 5MP always worked for me.

You`ve seen some of my earlier PCBs then ...

mebbe one of thise things where spend mre time trying methods of making PCBs than actually making the boards.

Then when it gets past proto can get screened, resisted ,gold plated beauties for less per unit cost than can get bare board.

Used to do pretty well with inkjet transparency on an Epson 600
