whereas it is NOT with a typical ink jet that needs to be run at least once a week or the heads get clogged.Check out this Amazon review of Canon Pixma G1000 Refillable Ink Tank Printer
The product is good. Unlike other ink tank printers heads come separatelywww.amazon.in
So this Canon PIXMA G1000 is an ink tank
People on this board with ink tank printers told me that occasional printing with an ink tank was ok whereas it is NOT with a typical ink jet that needs to be run at least once a week or the heads get clogged.
OP's problem is clogged heads because of occasional printing. You see the printer runs a periodic maintenance service where it flushes ink through the heads when it is left unused for an extended period. But it needs to be plugged in and there are some people who object to this self-clean mode thinking of it as waste. It is not waste. If you want your ink tank to work with unclogged print heads then that is the price you pay.
This is the main reason i went with a laser printer. BW though as colour ones are not available at the right price in India unlike in other markets.
Bro all Canon Pixma printers need to be run atleast once a week. Why you have mentioned the opposite?
As per my experience self/deep cleaning is a waste of ink.
You are right laser printers are the way to go. Learnt this lesson later. BTW which printer are you using and how much did you pay for it?
