Canon PIXMA TR7820
The PIXMA TR7820 is the document worker of this group: a home-office all-in-one with an automatic document feeder and full wireless, printing from the same two-cartridge FINE system — the PG-285XL black, up to 400 pages, and the CL-286XL tri-color, up to 400 pages, in the sizes stocked here. The family's standard PG-285 and CL-286 cartridges are rated for up to 180 pages each.
A feeder changes what a printer is for: stacks of forms, signed pages and receipts move through the TR7820 as scans and copies all day, and the ink it spends is overwhelmingly black. Its two-slot design keeps that habit cheap to feed — one cartridge decision at a time, with the printhead renewed at every change, so a unit that sat through a quiet year usually needs ink, not a technician.

Which cartridge should you buy?
In a feeder-equipped office the black cartridge does the heavy lifting, so the PG-285XL is the one to buy ahead — documents, copies and faxes all draw on it. The CL-286XL matters when the office prints color handouts or photos; replace it when its output fades, independently of the black. Offices that never want the feeder idle keep the Set of 5 as shelf stock, in the black-heavy mix these printers actually consume, and the Set of 2 covers a full refresh when both slots run down together.
Chip, ink and everyday use
Before pricing a repair for streaky copies, price a cartridge: on this platform the printhead lives in the cartridge, not the printer, so a swap renews it and most streaks trace back to the unit, not the machine. Each cartridge carries a new compatible chip, so levels report normally. The family recipe is pigment black for documents and dye tri-color for color work. Store spares sealed and upright, and open the packaging only when the printer asks for the swap.
Frequently Asked Questions
Which cartridges does the TR7820 use?
The PG-285XL black and CL-286XL tri-color in the XL sizes sold here, each up to 400 pages; the standard PG-285 and CL-286 sizes are rated for up to 180 pages.
Does scanning through the feeder use ink?
No — scanning consumes no ink at all. Copies do, since a copy is printed; a day of pure scanning leaves both cartridges untouched.
Why does my office go through black so much faster than color?
Documents are black work: text pages, forms and copies draw almost entirely on the pigment black cartridge. Color is spent mainly on graphics and photos, so its cartridge lasts through far more calendar time.
Both cartridges are low and the printer sat idle for months. One order?
Yes — the Set of 2 replaces both positions together, which also gives you two fresh printheads, the surest reset for a machine coming back from a long rest. Both sets here are Clever Supplies compatibles covered by our Lifetime Warranty.
