Does printer recognize reset chips?

[MP640]

When I reset the chips on my Canon 520/521 cartridges would the printer (MP640) be able to tell that the chips were reset? The reason I'm asking is that today I refilled my genuine Canon cartridges and reset the chips. After the refills/resets the cleaning cycles have increased dramatically. Yellow is half empty after printing 10 pages, most of which were black text.

Who knows? Those that do, such as Canon employees, don't seem to be talking.

Your empirical evidence suggests the possibility. Those who have done warranty service on a refilled printer have never mentioned being hassled about refilling (as long as they did not admit to refilling or left a refilled cartridge in the printer when sent in for service), providing other empirical evidence that there is no recording of using reset chip.

The printer does monitor if you have overridden ink monitoring, ie used the cartridge after it has been flagged as empty but before you reset the chip. Maybe this would trigger a failsafe measure of increased cleaning cycles, potentially for the rest of the life of the printer.

Just curious, how do you know the cleaning cycles are more often than if you hadn't used a chip resetter? Do you have two identical printers, one you refill and another that only uses new OEM cartridges? Also, have you overridden either printer's ink monitoring function to squeeze a printjob out of the residual ink?


The color cartridges may be used in making dark/black colors. My yellow dye ink cartridge is used about twice as fast as the next used color. It all depends on what you print. But I do agree that there seems to be a lot of cleaning with my printer, though some of these specific functions are not draining ink from cartridges from what I've read.

I have one mp640. After the cartridges that came in the box were empty, I loaded the printer with refilled cartridges with auto reset chips. I noticed immediately that there were many more cleaning cycles. I then refilled the empty canon cartridges that originally came with the printer and disabled the ink monitoring. Same result; many and lengthy cleaning cycles. Then I bought a set of genuine Canon 520/521 cartridges and the number and length of the cleaning cylcles decreased. Today, I reset the chips and refilled the cartridges and back were the cleaning cycles. I have downloaded The Canon service tool and reset the printer's EEPROM but without success. Still many cleaning cycles.

The INK_OFF value in the EEPROM listing before and after the reset are INK_OFF(PBK=1 BK=0 Y=1 M=1 C=1)

My experience is that the printer works ok with genuine Canon cartridges. When you refill, disable ink monitoring or reset chips the cleaning cycles will increase. When you revert to OEM, it will work fine again.

The reliability of aftermarket cartridges and ink is, on the whole, not as good as new OEM Canon replacements. Intuitively, it makes sense that Canon might add more maintenance if it detected less than brand new OEM cartridges. How it would do this is conjecture - an alphanumeric code of some type, a chip reset counter??

The silver lining to these potential increased maintenance functions is an OEM Canon cartridge refilled with aftermarket inks cost ~80-90% less than a new OEM Canon cartridge. The cloud remaining is a purge pad that fills up quicker requiring expensive or dirty replacement work.

It remains to be seen if these increased maintenance functions, if real, are to punish or safeguard (against lawsuit by) the end user (that would be "us"). I know there is a lot of exasperation by refillers with Canon's protective strategies, but they are allowed to do business as they see fit as long as it does not break the law. I don't blame or curse Canon because they want to protect their legitimate business interests, though I wish they kept making the better quality older models like my MP830.

We do what we do, they do what they do. Since the money is in consummables, the protection of the business will be geared towards that side. Making printers using cheaper, shorter lifespan components also provides increased revenues from turnover. Very few businesses who deal in goods (rather than services) operate differently.

I've noticed extra cleaning cycles can't be disabled in the IP4700 like they were in the IP4600. With the older model disabling ink monitoring actually made your cartridges last longer cause it would hardly ever run cleaning cycles except if you hadn't printed in a few days. The IP4700 on the other hand was the opposite. Slightly increased cleaning cycles with ink monitoring on and endless cleaning cycles before a print and in between nearly every page of printing with it disabled. Either situation has you wasting more ink than the previous generation printer and for no good reason, the IP4600 I had hardly ever clogged and I refilled it dozens of times with generic Stratitec ink in generic G&G cartridges that I transferred empty genuine chips on.

The only conclusion I could come up with for releasing the IP4700 is discouraging refilling with even more excessive cleaning cycles which the IP4600 was already infamous for. There is almost nothing different about the IP4700, same print head, same cartridges, it may or may not have been faster printing a page but it was harder to tell because it took longer to get that first page out and cleaning in between pages slowed page to page progression. So reset chips or not I believe MP640 has noticed a trend in his Canon printer. It's why I shelved my IP4700 and switched to an Epson Artisan 50. Slow as molasses compared to the Canon but better color reproduction and a 6 color CISS lasts a good long time with the benefit of no more refilling hassles.

qwertydude:

It doesn't sound as if resetting chips were your issue for increased maintenance cycles. Are your experiences with maintenance cycles BETWEEN pages of a print job is bizarre. Could it be you had a "lemon"? Anyone else with this occurring with either ink monitoring turned off and not using a chip resetter or when using a chip resetter and ink monitoring never turned off?

I am not surprised if Canon printers had more maintenance cycles if you disabled ink monitoring. I am also not surprised that newer models may have more maintenance events for whatever reasoning - altered tolerances due to design/manufacturing/parts reasons, or desire to have fewer customer support calls, or a desire for customers to burn through ink faster to increase sales.

My experience is not unique, it's already been mentioned by others in this forum. I had both the IP4600 AND the IP4700 and to me there was no reason to even release the IP4700 considering how well my IP4600 worked even considering how much "refill abuse" I subjected it to. The only really big difference I noticed and others on this site noticed is extra cleaning cycles, yes even between prints too.

 

[stratman]

If I understand you correctly, you said that the newer printer models have more maintenance cycles and these cleaning cycles are made more frequent if you disable ink monitoring. What is unclear to me is if one used a chip resetter and refilled Canon cartridges that the cleaning cycles reamin the same as if one always used only new Canon cartridges.

The distinction is important since the OP was questioning if using a chip resetter altered maintenance cycle events.

 

[MP640]

Yes, everything Qwertydude states about his 4700 I experience with my MP640. Onlu when I switched to new canon cartridges things went "back to normal". The only diffference now is that I have reset the chips and refilled the cartridges. I assume that the printer doesn't recognize non-Canon ink, so the only difference is in the reset chips.

MP640: It seems to me, that reset chips would have nothing to do with more frequent cleaning cycles, but rather the quality or type of ink used for refills certainly would. You dont specify what ink was used for refill. It may well be that this ink has a faster drying time, or is thicker than OEM Canon Ink and consequently clogs the nozzles faster. Such would indeed make for more frequent cleaning episodes. Reset chips would only affect the ink monitoring system. What ink are you using for refills? What refill method are you utilizing?
