Electronics Forum / Basics / August 2006Making an ink-level sensor for an inkjet printer
After refilling one of the Canon inkjets with the newer chipped carts (ip4200, etc), one loses the ability to monitor the ink levels using the printer's cirquitry and software. This is unfortunate. It occurred to me that it would be quite easy to make a low-cost add-on ink level warning device - comprising a sensor that detects when the rear portion of the cartridge (the chamber with no sponge inside) runs dry. This could be achieved with a two-terminal sensor that detects increased electrical resistance when there is no longer any ink between the terminals. The terminals could project from the end of a rod that extends down into the cartridge from the top. It could be inserted after drilling a hole - one for each cart. The sensors could cause an LED to light up (one for each cart). It could also set off a beeper. If anyone ends up building one, please send me one - or at least the instructions and component list. I'd do it myself but my knowledge of electronics is too scant.

The last thing I want is to have to sit and monitor ink levels manually. Even one color running out of ink without my being aware of it could cost me a lot of re-printing and possibly destroy the print head. Al D > I do long print runs (4000 sheets).

I see them on eBay for certain printers. Your chip kit is no good if it doesn't properly reset the cartridge. >Consider a bulk kit - external tanks of ink with light hoses.

Yes, they are certainly an oprion - although I haven't seen one advertised for the ip4200. >Your chip kit is no good if it doesn't properly reset the cartridge. I am suggesting something that works independedntly of the chip, and the computer. So resetting the cartridge is irrelevant. You can't reset the chips on Canon cartridges anyway.

SignatureBye. Jasen > put the sensor "4000 pages" from the bottom of the tank. Another of your usual useless replies? You don't use the same amount of ink with different layouts, and if he was only ever to print one thing, it would be cheaper to have it done in a larger run on a color printing press. Now, tell us, in full detail EXACTLY how to "put the sensor "4000 pages" from the bottom of the tank". SignatureService to my country? Been there, Done that, and I've got my DD214 to prove it.

It's easy. Just get a page ruler and measure up 4000 pages. >> put the sensor "4000 pages" from the bottom of the tank. > > Another of your usual useless replies?

Characterise the ink usage for 4000 pages take the 99th percentile figure put that much ink in the tank and position the sensor there. if 1% isn't an acceptable risk go higher. I think most people who print large volumes print mostly the same sort of stuff so the 99th percentile may be only a litte more than the mean. Bye. Jasen > >> put the sensor "4000 pages" from the bottom of the tank. > > [quoted text clipped - 16 lines] > Bye. > Jasen Some people print a lot of graphics, while others print only partial pages of text. Some people use their printer all day long, causing very few cleaning cycles, while others rarely turn it on and use more ink in cleaning cycles than in printing. Its a lead balloon, it just won't fly. SignatureService to my country? Been there, Done that, and I've got my DD214 to prove it. Member of DAV #85. Michael A.

To my knowledge nobody has managed to produce a Canon chip resetter. Al D What would be the electrolysis effect on the ink? this is out of the realm of my expertise, just queries.
