toner refill too light


V

Vic Dura

Has anyone ever encountered toner refill that is too light?

I refilled a b/w samsung ML-1710D3 and immediately the pages started
printing about 25% too light. The printing is uniformly light, so it
looks to me like the toner powder is not dark enough. Is that
possible? Has anyone else ever encountered something like that after a
refill with any brand of b/w laser printer?

I have little experience with Samsung cartridges.
What I can say is that Brother cartridges suffer this problem if every scrap of
toner is not removed from the toner cartridge before refilling. This is due to
developer remaining in the cartridge at too high a percentage. This causes a
gray rather than a good black output.
I do not know if this applies to Samsung cartridges.

Thanks for the info Tony. I did not remove all the remaining toner
from the 1710 cartridge before refilling. However, there wasn't much
left and after printing a couple of hundred pages following the
refill, the printing is still uniformly light.

What is the "developer" that remains in the cartridge? I've never read
anything about "developer" in a laser cartridge.

Have you tried darkening the print in the Samsung's print monito
window..

Could it be that the toner is different, might be the toner itself..

I have a ML1510, it's had two or three refills and when I do largis
areas of print it starting to show greyish streaks, as opposed t
your's. Quite ok on text but expect it to get worse...cos the OP
drum in the assembley started to wear or at least I think

It's had some clobber from printing PCB designs etc using tone
transfer film which it stll seems to handle. along with tex
documents. The printer was £54 inc delivery....the toner abou
£64.....lol

I did come across a site that sold the OPC drum for this model, ye
the OPC drum the one in the toner unit, but can I find it....b
awful good fun fitting it..! But can I find the site again..

It's the ol' Lexmark question, a new printer or a new toner - which..

window..?

Yes, that was the first thing I tried, but it had no noticeable
effect.

Yes, that is what I'm thinking.

I purchased the toner from WeInk.com and loaded all the toner into the
cartridge. It was the first refill of the original (came with the
printer) 1/3 full samsung cartridge; so I don't think any other
component was worn out. Immediately when I started printing with the
refilled cartridge all of the text was uniformly about 25% light. When
I switched back to a samsung OEM cartridge the printing was "normal".

Vic what does the toner powder look like...OK, OK better put it
another way.

Did the powder look grey when you was filling it or did it look black
as you would expect, wonder if the fusion temperature plays a roll
here.

Get some on a paper, place a sheet of paper over the top....and press
it with a hot iron.... do my shirt while your at it..!

Need be on cotton or linen setting, play with a lower setting to try
and get the same result.

Doesn't Samsung claim to use an extra-fine particle toner? Less dark
could mean not enough (or "heavier") toner is adhering to the drum
before being fused to the paper.

It looked black. It didn't look any different from the residual toner
that was in the cartridge, but I wasn't looking for any differences. I
was more concerned with not spilling it.

Thanks for the suggestion, but I don't want to be messing with it. I'm
just going to write it off as not being up to OEM specs for whatever
reason and try another brand next time. I was just wondering if anyone
else had encountered something like this before.

Best regards,

I don't know Brendan. That could explain what I am seeing.

Thanks for the suggestion.

So far as i know all laser printers and laser photocopiers use developer, in
some cases the developer is mixed with the toner and in some it is in a
seperate container (more common with photocopiers). Both toner and developer
are essential for the printing process to work.
The issue I was referring to (which may not apply to your printer) is that the
waste toner produced during printing has a higher ratio of developer to toner
than the original toner, if the printer has a waste toner compartment this is
no problem since the waste toner gets thrown away at some stage.
But if the printer does not have a waste toner compartment but puts the waste
toner back into the toner compartment then at some stage the ratio in that
compartment will be too high. This happens in some Brother printers and can
manifest itself as a page with a gray background when the toner cartridge is
nearing empty. That is why removing all unused toner before refilling
cartridges from printers that have no waste toner hopper is essential. It is
also why re-using waste toner is ill-advised.
The quality of most toner available for refilling is very high indeed but there
are some traps. Generic or universal toner may not work well in all of the
printers that the manufacturer claims it is formulated for and in some cases
the supplier may not have done their homework and the toner is not properly
made. Once more this applies to a very small minority of available toners, if
you stick to good brands (like Static Control Corporation as one example of a
quality manufacturer) you will have no problem at all.

The only things that I can think of are either you have got some poor quality
toner or the Toner Save feature has been enabled in the printer driver.

Thanks for info about developer Tony. I didn't know that. The
instructions did refer to a "Developer roller", but there was no
separate developer included with the refill kit.

Since the Toner Save feature is not on, I'm just going to assume I got
a miss-match or poor quality toner. I didn't note the brand of toner
or even if a brand was indicated. I bought the toner kit from
WeInk.com.

Thanks for all your help.

Vic Dura
