Epson C82 Residual Ink when "empty"
Hi,
I have been reading old threads about the Epson C82 and chip resetters / refills etc. I have decided it is too risky to use 3rd party ink since my printer is brand new and there are many cases of 3rd part ink permanently clogging the print head. However, as pointed out, when the ink cartrige is designated "empty" on the chip, it seems like 20-40% of the ink still remains! I hate throwing out good ink! I know there are affordable chip resetter available that reset the ink chip into thinking the cartrige is full again. Is it safe to do this and re-run the same ink cartrige until it is literally dry? I read a few posts about thermal overheating if printing when there is no ink. But other posts discounted this, as the Epson uses piezoelectric charge to jet the ink, not heat. Is it safe to run down your ink cartridges to dry with the C82? |

There is always a risk of head damage when resetting old cartridges.
Unfortunately the Epson methods are at best a guesstimate - or counting cycles instead of a prism measuring ink. The other risk is that few if any alternate ink suppliers can supply pigmented ink for the C82. Possible the jetTec cartridges are a neat half way solution they are half the Epson price. As below... -- Inkylink JetTec UK Quality - Wot others wanna-be Epson 950 C70/80/82 Lighfast pigmented inks. Canon BCI-3 i750 BCI-6 S-820 / S-900 series. www.aah-haa.com "Sabian Smith" wrote in message le.rogers.com...

Piezoelectric membranes can seriously overheat if there is no ink inside the cavities. The amplitude of vibration becames much larger and energy of electrical pulses is fully converted into heat. Additionally air is much worse cooling agent than ink. Prolonged "dry" printing (sometimes even a page or two) can kill the printhead - especially if the printhead is fast and contains a large number of nozzles. For example stc900 printhead has built-in thermistor - in case of enormous heat inside the printhead the cleaning cycle is automatically applied as the heat is caused by lack of ink flow. Is it safe to run down your ink cartridges to dry with the C82? IMHO it isn't. You should be careful and stop printing just after the ink ends. Additionally the cleaning cycle applied after the cartridge change is most probably not strong enough to "prime" empty printhead and additional cycles must be applied manually. Best regards Lukasz |
