Inkjet Cleaning Costs

  wee eddie 04:44 01 Nov 2010

There is a somewhat OTT Thread running which blames one Machine for using excess ink during the Cleaning Process. It may, or may not, be true.

My experience is that all Inkjets use a small amount of Ink to clean the Print Heads, every time the Machine is turned on, more Ink is used if the machine is only used infrequently.

Now ~ My question is this.

Is there a way of knowing how much of ones "Valuable" Ink is used each time that "On" Switch, of Machine A or B, is pressed?

I think that this would be a suitable piece of Research for the Team at PCA Headquarters.

It would be bound to take time because a day, or three, would have to elapse between each cycle, in which the Printer was turned on. Otherwise the Cleaning Process would not be similar to a Domestic Situation as , a fair proportion of us, only use our Printers once or twice a week.

Has oft been discussed here.
The simple answer is to not switch it off and to run at least one full colour page a week[more in warm weather] to keep it sweet
As for measuring the amount used per clean,- researching that would be a waste of time and ink,
When its gone its gone.

With the amount of printing that I do, it is likely that more ink is used cleaning the Heads than printing the few pages that I write.

I am merely suggesting it, as a Research Project for the PCA Team, because none of us know how much ink is used.

I use a Brother printer, which is switched on and off and used daily, yet it appears to have an automated clean process only occasionally. The cost of the cartridges are extremely cheap, so I suppose I am one of the few that isn't worried about ink costs?.

It may be that infrequent use, say, once every couple of weeks, costs more in Ink use, per Page Printed, than regular use as in your example.

The constant head cleaning business as I mentioned earlier has been discussed many times here especially in respect of Epson machines and the advice given is 'leave it switched' on.
This may of course only be a factor in Epson machines - SPUDS-Brother for example seems to operate on other principles and so too may not.
Coming back to measuring the use of ink- I can only think of one practical way of doing it.
Certainly the ink use indicators are only software guesstimates based on the number of sheets passed, no way a measure of ink volume consumed.
The only way to do this exercise it seems to me is to weigh the cartridge in its new condition before insertion and then weigh it after each clean cycle
- if you have scales accurate enough to measure grams or fractions thereof.

Weighing Change, or rate of Change, is not that difficult with a school set of Balances.

I am not suggesting you you, or I, do the research. Any more than I would suggest that you and I do the research to discover which is the better printer. That's the work for PCA Specialists.

My Canon i850 appears to be a very capable printer. It gets turned on, roughly, once each week, cleans itself and then I print 6 Time Sheets, sometimes a letter or two and then turn it off. About once every 10 weeks, or so, it needs a deep clean as the Ink appears to dry in the Print Heads.

Now I have no idea how much Ink is used, in the Cleaning Process, each time but it must skew the Cost per Sheet estimates, given by the Manufacturer. I would really like to know how much, of each Ink Tank, is being used for Cleaning under these conditions.

Incidentally, I don't think that Laser Printers use Toner to Clean their Plates, or whatever they have. That consideration alone might make the Laser Printer a much better deal for the "Occasional" User.

In certain Epson machines may be others too] is to construct an external collector- much favoured by CISS users - way to do this has been much discussed here
Your purposes of course is to measure the volume of ink not being used to print-
The original purpose if course was to bypass the need to change the printers'nappy

My purpose is "NOT" to find out.

My purpose is to get the Reviewers to discuss the Overall Ink Use, rather than just that which appears on each Printed Page.

I think that when someone takes the time to do the research, the results may be something of an eyeopener. My guess is that the "Occasional" User is consuming about 20% of his Ink Purchased on the Cleaning Process.

Once the research is published, I would expect most the Manufacturers to be adding some form of, Ink Free, Cleaning Mechanism to all their printers, that runs of a liquid that is considerably cheaper than the Ink currently used.

Im with you on this one,
for prints Ive only ever used Epson inkjets over the last 16years, my latest the R800 drinks Cyan even when printing monochrome pics,and the head cleaning sequence drinks ink,even if the printer is left on,it still performs the head cleaning before printing,

The plus side is that with original carts it produces better pics than samples of other printers

This is true for all 'Monochrome' inkjet printing.
To get a true black or range of greys all colours are deployed- use a jewellers lupe and take a look at a 'Monochrome' print some time.
Some printers due have a 'black only' setting- but is is usually a very weak black- except possible for some lasers.
My DELL 1320 colour laser for example has a 'Black only' setting and is a good true black
