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: 4451C032
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 — INKJET all-in-one (print/scan/copy/fax): A compact home-office PIXMA inkjet AIO. Inkjet printheads CLOG if unused — faded/streaked/missing colours are usually a clog; run the printer's nozzle check and cleaning/deep-cleaning cycle. Print regularly to prevent it.
Cartridges: Uses Canon ink cartridges (a pigment black for text plus dye colours on many PIXMAs); a low/empty or wrong cartridge causes missing output. Reseat and remove the protective tape on new cartridges.
Connectivity: Wi-Fi/USB via the Canon PRINT/Canon app; 'offline' is usually a Wi-Fi drop or wrong queue (Canon printers also prefer 2.4 GHz).

Questions that only have an answer for the Canon PIXMA TR8620a

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.

My Canon PIXMA TR8620a prints blank or streaky pages.+

That is an inkjet printhead clog, common after the printer sits idle. Run the nozzle check, then Cleaning, and if needed Deep Cleaning, from the printer menu or the Canon software, printing a nozzle pattern after each to see improvement. Check the ink levels and that new cartridges had their tape removed and clicked in. Repeat cleaning a couple of times for a stubborn clog (it uses ink). Printing at least weekly prevents clogs from recurring.
