This is an EE forum so I might as well post some more possibly interesting bits about this:

http://www.eddiem.com/photo/CIS/inkchip/chip.html

Not much info (if at all) on the 'net about hacking the firmware, however - that's something I'd like to see, and I do have a printer or two I could play with, but I just don't have the time...

99.99% of my printing is B&W

Whats wrong with laser printer ?


At the time I bought it, it did a better job at printing dark black to transparencies for PCB artwork than did comparably priced laser printers.

If thats the case, just visit aliexpress, search for "epson chip resetter" or "reseter" , you will get tons of choices a small gadget that can reset the ink chip counter, and for sure they're cheaper than $60.

Just make sure your printer model is in the supported printer list.

from the link i provided indicated that the 4530's tank is sensor based detection hence do not need chip reset. just refill the tank, and the counter is back full again.
ah my bad... its indeed an internal chip counting mechanism thing...
How to reset the Epson Workforce WP-4020-WP-4530-WP-4540 cartridge chip and the maintenance box chip


What I didn't say in my previous post is, the old one failed after some 7 years of a good service which is to be considered a very good figure
yes also with your points. what i didnt mention is previous post is i'm talking specifically at $50 low grade canon. higher grade canon may last longer. indeed 7 years is very good, you are the first person i heard saying it. top i heard is 3-4 years, and in my case, changing cartridges (with the built in head) is equivalent of buying a new $50 printer each year. canon must have had matured all this while so they know the right amount of copper or whatever material to be used for such duration of operation. as people said, the good old days, today is not that good anymore. ymmv.

thank you very much for the link. its also in my to-do or to-find thing, but similarly to you... I just don't have the time...

I also mostly print B&W - and so have a dirt cheap Laser I've had for years (Samsung MLP-2010). It is very easy to crack open the cart and refill with cheap toner.

With the Epson Stylus print engines, my BX-300F is the very common 2880 dpi 4 colour design, but has useless sheetfeed and scanner, and (obsolete faxmodem) too.

My brother who has the same print engine but in a straight printer only design installled a constant inking system with bottles on the side of the printer, and a defeat chip. Great for mass colour printing, but at some point the print head itself becomes clogged.

I just bought a stash of really cheap sealed colour carts with hacked chips from ebay as didn't fancy all the messing. Serves me well.

I was using Canon printers and suggesting them to my customers and friends because of bad experiences with both HP and Epson.
Now I see many EXPENSIVE Canon printers fail with many different symptoms, and the spare parts (when availble) are too expensive.
If your printer fails and you have a stock of spare ink cartridges you can be sure that they will not fit the new printer, so you must throw away both the printer and the ink cartridges (if you supplier will not take them back).
That's foolish!
Now I bought an Epson Workforce Pro, and I'm happy with it (cartridges are expensive but last for a really high number of pages), and I understand that it will have a limited lifespan, but at least there is a service center not far from  my office.

Best regards
Ciccio

Since I virtually never need to print anything, for me inkjet printers are most useful as a source of nice straight polished steel rods. Every printer has at least one, usually several. Same with laser printers. Often they are stainless steel too.
I've accumulated quite a big box of printer rails, so anytime I need a steel rod I usually have something just right.
Stepper motors and even the big felt pads used as waste ink nappies can be useful too.

I should almost thank Canon and all the rest, for perfecting planned obsolescence so well that the streets are often lined with tossed-out printers, slightly useful for tinkerers. But no... damn them and their corporate greed.

In the end to "fix" the problem I had to pull the printer apart. I'm gobsmacked at just how crappy the design of some parts of this thing are. Each color ink is made to pass through a pressure reservoir (the largest one is black, the other three are cyan, magenta and yellow).

When fully assembled, a spring loaded piston permanently presses against the flexible membrane of each reservoir. The design flaw, obviously, is the stupid lolly wrapper-like membrane glued in place over each reservoir that seals in the ink.

In order to get the printer going gain without dribbling yellow ink over every page, I peeled the leaking yellow membrane away, let the ink drain and cleaned the reservoir out (metho + tissues). I then filled it with 5 minute Araldite.

The other two small bubble films look like they are just about to give up too.
You should have kept going with the disassembly. Like this Pixma MP500 I recently recycled.
The most disgusting thing about ink jet printers is the huge blotting pad in the bowels, that in any slightly old printer is always sodden with wasted ink. I think the majority of the so-expensive ink ends up here.

Because a real diaphragm (or piston with gasket seal) and retainer would be too expensive...

There are conversions around to replace the waste ink pad with an external bottle; you can't get around the waste however as the cleaning process involves sucking ink through the nozzles to unclog them.

I think the existing scheme could have been made a lot more durable, and not much more expensive, if there was more plastic for the membrane to be glued down to. The rim of each reservoir is very thin.

I put quite a lot of Araldite around the circumferences of the other membranes, so that should help seal them up.

I read that the Epson printers count characters and after a fixed number tell you the ink is empty,This applies to all characters so if you print nothing but full stops when you achieve the magic number of x thousands the machine stops due to no ink despite the cartridges beefing virtually full still. Reset the chip and you can start printing again, I have never tried printing all full stops but have reset a cartridge and been able to print another 50 plus pages.

I don't know what the specifics of this model printer are, but from now on whenever I print I will just make sure that the color option is set to either B&W or grey scale. Hopefully then it will not decrement any counters for the color inks. I'll just have to see how it goes.

Yellow will still be used as it is the colour used for the secret stenographic serial number printed on each page. At least now you have a stealth printer.
