Confirm the model first

Which units this covers, and how to tell yours is one of them

Every answer below is scoped to these model identifiers. A neighbouring model in the same line can use a different part, a different reset sequence or a different radio, so matching the identifier before following a procedure is the step that decides whether the rest of the page applies to you.

Model numbers and patterns: 3113C002
What that covers: Canon printer; PIXMA/MegaTank/MAXIFY/imageCLASS ink/toner systems and maintenance paths differ.

Published specification

What is true of this model and changes how you fix it

These are the properties that decide which procedure applies. Each is read from the manufacturer’s own published figures for this model, not carried over from a sibling that shares its retail name.

Type — refillable INK TANK all-in-one (MegaTank): A cartridge-free MegaTank inkjet AIO — refill ink BOTTLES for very low cost per page. Still inkjet, so the printhead can CLOG if unused. No fax on this model versus the G7020.
Initial charging & refills: First setup charges the printhead with starter ink (normal). Refill the matching bottle when low; do not run tanks dry.
Connectivity: Wi-Fi/USB via the Canon app; 'offline' is usually a Wi-Fi drop or wrong queue.

Exact questions

Questions that only have an answer for the Canon MegaTank PIXMA G6020

Each answer below uses this model’s own published figures. The same question asked about a different model in the line has a different answer, which is why it is answered here rather than on a general page.

Is the Canon MegaTank G6020 worth it over a cartridge printer?+

For regular printing, yes — the MegaTank uses cheap refillable ink bottles instead of cartridges, so the cost per page is a fraction of a cartridge printer and a set of bottles lasts thousands of pages. The trade-offs are a higher purchase price and that it is still an inkjet, so leaving it idle can clog the printhead (print occasionally and run cleaning if output fades). For steady home/small-office volume it saves a lot over time.

Structured depth, not empty permutations
