From: IntergalacticExpandingPanda on 21 Nov 2008 21:17 I should add, if you elect to troubleshoot the printer, you'll need the service manual https://www.tradebit.com/filedetail.php/3072034-canon-i860-i865-service-manual Presuming you have two i860s, it's very much possible to take the logic board from a known good one, and put it in the leaky one. That should help isolate whether or not it's an electronic problem or a mechanical one. If you have a technical staff willing to do this, great. Expect them to be very very busy for a day at least. If you plan to keep your i860s in service as long as possible, if you plan to replace the waste pads, you absolutely need the service manual. I think $5.20USD for the PDF is the cheapest you'll find it. You may also want the parts catalog as well, presuming it doesn't come with the service manual. If your main application is text printing, a new unit won't offer much in the way of improvement if any.
From: Arthur Entlich on 23 Nov 2008 03:37 Most inkjet printers, especially consumer models, don't actually monitor the waste ink pads. What they do is monitor the amount of ink that is assumed to go down the waste ink tube(s) with each cleaning cycle, or purge cycle. After a set number of "drops" are reached they warn or shut down. With Epson printers, as one example, should a head clog, and you run many cleaning cycles, even though no ink may have actually passed out the cartridge and head to the waste ink pads, that ink is still counted as used waste ink, and assumed to be in the pads. Also, with Epson's printers since I know them the best, the numbers are very conservative, so they tend to shut down when the ink saturation is about half or less of what the pads can tolerate. Also, much of the ink (probably at least 50%) is made up of volatiles which evaporate over time, so if you aren't using your printer and running many cleaning cycles regularly, much f this ink is reduced in volume evaporates. The main ingredients left over are the pigments of dyes themselves, glycerin and glycols which are agents to slow drying prevent clogging and to thicken the ink. Most inkjet printers have a waste ink level reset, some through pressing a series of front panel controls in the correct sequence and other via a software program. Epson now offers this information on line, when it used to only be available to service depots. Some other brands offer this information through other sources. Some people successfully reroute the waste ink tube from inside the printer to outside and then place the tube into a jar. This way the ink goes there and can be monitored, and although one would still have to reset the waste ink monitor, the ink doesn't end up contaminating the pads and leaking from the printer. Some people go as far as to successfully reuse the waste ink as basic black ink for text applications in an older printer, which is better than discarding this ink, since glycols are toxic in the environment.

From: Arthur Entlich on 23 Nov 2008 03:50 Obviously, what is happening with your printer is not normal, and you need to determine the cause to figure out under what circumstances it is losing ink. Removing the cartridge is not a reasonable answer. The machine will probably run extra cleaning cycles, you will introduce air into the heads which will cause printing defects, and the head will dry out if it is left without cartridges installed. I see no realistic answer beyond repairing the unit or replacing it. again, Canon or service people should be able to detect the nature of the defect and tell you if it makes sense economically to repair the unit. The continued wasting of numerous OEM ink cartridges doesn't make any sense, IMHO.

Arthur bought up the subject of models that can route ink to a jar. This is likely less desirable in an office environment since that jar can spill. What makes sense to reduce waste is 1) Laser Lasers by their very nature go much longer and faster without service than inkjets. There are some models that you have to replace parts over 10,000 to 30,000+ pages that can actually be done by the end user. These tend to take more basic cartridges and cost very little per page to operate. Most lasers these days recycle their waste toner. 2) Professional inkjets 1 network inkjet used by the staff is far more likely to enjoy continuous use and not waste the ink into the pads. HP has quote a few "business jet" models where the cartridges are double the cost of canon, but offer triple the yield. These guys have heads that you can replace, and actually they enjoy a longer service life than canon. Prices of these units tend to be twice to three times a base canon model. The advantage is you don't have to much with it so much. The disadvantage photo printing tends to be really good on $100-$150 inkjet models.
