Does printer recognize reset chips?

[The Hat]

For those that are interested I have an ip4700 with a CISS system working (well).
The main reason I wanted to mention that is I am using CISS cartridges with the ARC in them which means each time I want to print a single or multiple sheet the printer does a cleaning cycle.
Because of the ARC chip the printer registers new cartridges each time on power up hence the big clean, but as mentioned earlier it will do a wash and shave in the middle of a print job quite often, but it also did that with new OEM cartridges as well.
I just couldnt possibly afford to run this printer on Canon inks.
I have an ip4300 with CISS and ink monitoring turned off, rarely doe it a cleaning cycle that is noticeable likewise my ix4000.
So I have two printers with ink monitoring off and one with ARC the rest with OEM cartridges (top fill) and reset, the only one that washes more than a cat is the ip4700.
Meow..

@Ruffin, my ink is from Inkbank (www.inkbank.com.au). I use the German Durchstich refill method and a chip resetter. I don't think the printer has a means of establishing the ink quality, it would also run with water in the cartridges. Based on the information I have, the cleaning cycles are triggered by number of printed pages and time elapsed during the last cycle (information from the IP5200 service manual).

I made an EEPROM dump from my printer and am trying to understand what's in there. I also have reset the EEPROM, which was rewarded with a big huge cleaning cycle when I switched the printer out of maintenance mode (it thought it was new again). What I can see is that disabling the ink monitoring is logged in the EEPROM and resetting does not erase this info.

I have a MP640 and refill using the German method. After resetting the chips on the OEM carts,I haven't noticed any more frequent cleaning cycles than when using factory new carts. Maybe I'm just lucky. I do leave my printer powered on 24/7. Maybe that has something to do with it.

Hmm Canon is fast on the way of tarnishing their reputation much as Lexmark has.

I use Image Specialist ink from Precision Colors and reset my cartridge chips with a Redsetter. There is no apparent increase in cleaning cycles. Very happy with setup and Canon printers. Regards

Ruffin & mowerman90, have you ever turned off the ink level detection on your MP6xx? I did so when chip resetters were not yet available and this is still logged in the EEPROM.

I don't leave my printer on 7x24 but it's always plugged in a powered socket.

Can we come to a consensus on these issues?

1) Newer model Canon printers that that use 220/221 and 520/521 and newer cartridges perform more maintenance cycles than printers that use CLI-8 and PGI-5 cartridges and older.

2) Each successive generation of Canon printers perform more maintenance functions.

3) Overriding ink monitoring on newer models (models ??) causes more maintenance cycles.

4) Overriding ink monitoring is permanently stored in (EE)PROM. (Is this the HDEEPROM section of the EEPROM print dump?)

5) The increased maintenance cycles caused when one has overriden ink monitoring can be returned to "normal" if new OEM Canon cartridges are used again.

6) Using ARC resetting chips causes a "new cartridge inserted" cleaning cycle each time the printer is turned on. Thereafter, the printer performs as it would if using New OEM Canon cartridges and not ARC chips.

7) A printer that has never had ink monitoring turned off but has used a chip resetter (not ARC chips) performs exactly as if only new OEM Canon cartridges, not reset ones, have ever been used.


MP640 -

Where in your EEPROM print dump is the ink monitoring override listed after your erased EEPROM? If you don't have the Service Mode EEPROM print dump explanation for your model then you can download one of an earlier Canon model at http://rapidshare.com/files/69569077/Canon_Service_Mode_EEPROM_Info_1.doc. Maybe it will help you decode your print dump. Let us know.

Stratman, I cannot confirm your bullet 7. The other 6 seem correct to me.

There's several lines in the dump that relate to the cartridges:

- CT(PBK=036 BK=058 Y=022 M=032 C=042) I think these are the counts that new cartridges have been inserted. If you have ARC chips, these figures should be pretty high. These reset to 0 after EEPROM reset.
- IL(PBK=1 BK=0 Y=0 M=0 C=0) I have no idea what these numbers mean; given it ar 0 or 1 values I think they are booleans (yes/no). These reset to 0 after EEPROM reset
- INK_OFF(PBK=1 BK=0 Y=1 M=1 C=1). These DON'T reset with EEPROM reset.

I've had no luck downloading the dump explanation. The site wants me to become a pro (=paying) account member. Could you email it to me at spamaccount9999 (at) hotmail (dot) com?

No, I've never turned off the ink monitoring in my MP640.

Rapidshare files can be downloaded for free. Choose Free Download and follow the directions/clicks/links. The download relates to earlier model Canons, not your current model, but there probably is sufficient concordance to gain a better understanding. A Service Manual for your specific printer would be the most beneficial overall.


"CT" = tank changes (ink tank replacement count)

"IL" = Ink ejection level (PBK, BK, Y, M, M2, C, C2)

"INK_OFF" = ??? --- Possibly number of times Ink Level Monitoring has been overridden per cartridge type?


It makes sense that certain data is not erased when you reset the EEPROM, such as model number, serial number, and other critical non-changing data. Maybe that is why INK_OFF is not erased -- it is important to know if the user has been turning off ink monitoring and that this could be why they have a service problem. Not only would this be something to discuss with the customer on how to avoid problems in the future but also a way to get out of covering the service under the warranty.
